How To Make Windows 10 Bootable USB Via Command Prompt

Last Updated on by 2,094 Comments

Do you want to install or reinstall Windows 10 on your computer? Not sure how to prepare the bootable USB of Windows 10 without using third-party tools? In this step-by-step, we will see how to prepare the bootable USB of Windows 10 using the Command Prompt.

Although one can always use tools like Rufus to prepare the bootable USB, why use a third-party tool when you can create the bootable USB using the built-in Command Prompt?

The method is straightforward, and you can use it without any hassles. Needless to say that your motherboard should support the USB Boot feature to make use of the bootable USB drive. And if your PC doesn’t support booting from USB, you can still install Windows from USB by following our how-to install Windows 7/8 from a USB drive even if your PC doesn’t support the USB boot feature.

How to install Windows 10 from the USB drive guide might also interest you.

Preparing Windows 10/8/7 bootable USB

Requirements:

  • USB Flash Drive (Minimum 4GB)
  • Windows 10/8/7 installation files.

Follow the below steps to create bootable Windows 10/Windows 7 USB drive using which you can install Windows 10/8/7 easily.

Procedure:

Step 1: Plug-in your USB flash drive to the USB port and move all the contents from the USB drive to a safe location on your system.

Step 2: Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt with admin rights.

*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.

Or

*Go to Start menu > All programs > Accessories, right-click on Command Prompt, and select Run as administrator.

Step 3: You need to know about the USB drive a little bit. Type in the following commands in the command prompt:

First, type DISKPART and hit enter to see the below message.

Bootable USB Drive

Next type the LIST DISK command and note down the Disk number (ex: Disk 1) of your USB flash drive. In the below screenshot, my Flash Drive Disk no is Disk 1.

Step 4: Next, type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive, then use Disk 2.Refer to the above step to confirm it.

So below are the commands you need to type and execute one by one:

SELECT DISK 1

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS Quick

(In the above command, replace NTFS with FAT32 if your system supports UEFI)

(Format process may take few seconds)

ASSIGN

EXIT

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

Bootable USB Drive

Step 5: Next, insert your Windows 10/8/7 DVD into the optical drive and check the drive letter of the DVD drive. In this guide, I will assume that your DVD drive letter is “D,” and the USB drive letter is “H” (open my computer to know about it). If you have an ISO image of Windows 10/8/7, mount the ISO file by right-clicking on it and then clicking the Mount option. It will now show up in File Explorer.

Step 6: Maximize the minimized Command Prompt in the 4th step.Type  the following command now:

D: CD BOOT and hit enter. Where “D” is your DVD drive letter or the drive letter of the mounted ISO file.

CD BOOT and hit enter to see the below message.

Step 7: Type another command given below to update the USB drive with BOOTMGR compatible code.

BOOTSECT.EXE /NT60 H:

14

Where “H” is your USB drive letter. Once you enter the above command, you will see the below message.

Step 8: Copy your Windows 10/8/7 contents to the USB flash drive. If you mounted an ISO file, open up the drive and copy all the files to the USB drive.

Step 9: Your USB drive is ready to boot and install Windows 10/8/7. The only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.

Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problems following this guide, feel free to ask questions by leaving a comment.

Update: If you find this guide difficult to follow, please use the easy-to-use Rufus software to create a bootable USB. Make sure you follow all steps correctly and launch the Command Prompt with admin rights (as given in the guide) to avoid errors. Good luck!

    I used this method successfully on two computers. I was very surprised that when I was unable to change the boot sequence to USB in the BIOS on an older laptop, windows 7 installed

    i have ubuntu in my thinpad.. but i want to remove ubuntu and install windows 7. it does not have dvd drive. i first formatted my usb drive. then pasted windows 7 prof. in it. restart the comp. and kept pressing f2. but did not show the booting message. the above method also did not work. is there any other options??

  7. Danny L says

    And, completely useless and irrelevant. This doesn’t tell you shit about how to install Win from a USB drive. If I’d been interested in how to MAKE such a drive, great! But, that’s not what it’s supposed to be. It’s supposed to be about HOW TO install. Which is where I’m having issues, and needed help. And before you try that, yes, the boot priority is on the USB drive, with the HDD set third, behind even network boot.

    Essentially? Why the hell did you make a wall of text that has NOTHING to do with actually installing? Talk about UTTERLY useless self-advertising. Clueless ass.

  8. Joe says

    Whew. This finally resolved my issue with “A required CD/DVD drive device driver is missing” error.

    I placed the HD of the computer giving the error into an enclosure, cleared it, created a primary partition size=10240, made it bootable then copied Windows 7 to it. I popped it back in the original computer, booted to setup, created other partition and installed.

    Thank you for this.

  9. Javier T says

    UNPLUG AND PLUG THE USB DRIVE AGAIN BEFORE RUN BOOTSECT.EXE, THEN CHECK IF THE USB DRIVE LETTER WAS CHANGED, FOR EXAMPLE FROM I: TO J:
    NOW TRY TO RUN BOOTSECT.EXE WITH THE NEW USB DRIVE LETTER.

    Sorry for the capital letters, but I wanted the message to be easily visible between so many error messages related to this reason.

    I created a bootable Win 7 Ultimate USB (Sandisk Cruzer) disk tonight. I followed your instructions to the letter & it worked. I didn’t go through the whole installation, just until before you have to format the C drive.

    My laptop is an Acer Aspire E1-431G V1.24. UEFI: Insyde Corp. V1.24 if that helps. You need to set ‘USB HDD’ to boot first in the BIOS (there are similar options like FDD, DVD etc).

    I think I’m home free for the full installation. Just waiting until I buy my new HD next week, Kingston Hyper-X SSD, before I reinstall.

    Also looking forward to trying out Win 10 using the same method, when they bring out the full version…

    p.s. My Windows 7 CD is very old & couldn’t be read by my DVD drive. I had to use a friends computer to copy the CD to (a different) USB drive, then copy that to the C drive on my computer. I just changed the relevant drive letters in the guide & it worked like a charm :-)

  15. Kiraee says

    I’ve been using this guide for some years now for every windows versión possible and it works.

    Btw, I have used this with windows 10 around 5 times already with different USB sticks and it works.

    hello,

    i’ve been doing the diskpart thing for my USB disk for quite sometime now and i’ve been able to install windows 7 on dozens of machines.

    but just this morning i get the message:

    Windows Boot Manager?
    Windows failed to start. A recent hardware or software change might be the ?cause. To fix the problem:

    1. Insert your Windows Installation disc and restart your computer.
    ?2. Choose your language settings and then click “Next”
    ?3. Click “Repair your computer”
    If you do not have this disc, contact your system administrator or computer ?manufacturer for assistance.

    File: \Boot\BCD

    ?Status: 0xc000000

    Info: An error occurred while attempting to read the boot configuration data.

    —

    My Windows 7 installation file is not an ISO and not in a DVD. I just copied the files onto the USB disk.

    Can you help me with this please ASAP.

    Thanks!

  21. Markus says

    The guide is definitely not working when attempting to install Windows 7 on Asus UX32L
    Neither does the guide with the windows tool.

    When chosing the USB as Boot device, the system just shows a back screen for a short time and then switcheds to the normal HD with the preinstalled win 8.1

    BTW no guides for any kind of USB Boot Stick work for this POS machine LOL

  23. Chandrashekar C says

    Awesome…. I am able to boot my USB!! thank you so much. Its very easy now. Once again Thank you.

  24. Dinesh Jangid says

    Thanks Dear,

    All things are set as shown in your guide but in starting message showing: Invalid partition.

    What to Do?

    Earlier I have successfully installed Windows 7 home basic with same specifications in the same configuration Desktop PC. But this time I tried to install Windows 7 Ultimate, which did’t succeed.

  43. JT says

    Is this reversible? Once I’ve done this and used it to boot up Windows, can I delete the contents and use it as a normal USB drive again? Thanks!

  46. Avach says

    Followed the steps (even tried with Win 7 USB DVD download tool), boot priority is set to USB. But nothing happenes, disabled other boot options and it just skips to bios. Tried with multiple flashdrives, the USB socket must be working as well.

    Any suggestions?

    I can do everything but when i get to…

    Step 7: Type another command given below to update the USB drive with BOOTMGR compatible code.
    BOOTSECT.EXE /NT60 H:

    It says…

    “Target volumes will be updated with BOOTMGR compatible bootcode.

    Could not map drive partitions to the associated volume device objects:
    Access is denied.”

    ???

    Answer: Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator. Then followed step 7 again, it will work.

  56. ntop says

    after i try to boot i get it to but when i start to install and it says i need a driver for my dvd drive and i dont know the make of my laptop to even get a driver. is there an alternative route around this?

  57. admin says

    @ Varazir
    Yes, there is an easier way to have Windows 7 and Windows 8 installation media on the same USB. Please go through the following post:
    intowindows.com/how-to-install-windows-7-and-windows-88-1-from-same-usb/

  58. Varazir says

    Is there a way to have both win7 and win8 installation media on the same USB drive and you get a boot up menu when you boot up the drive ?

  59. satyanarayana says

    F:\boot>bootsect.exe /nt60 f:
    this version of F:\boot>bootsect.exe is not compatible with the version of windows you’re running.
    check your computer’s system information to see whether you need a x86 (32 bit) or x64 (64 bit)
    version of the program, and then contact the software publisher.

  62. JOSH says

    so, i cant find where i went wrong but i cant complete step 7. the usb is seen as a MBR and not a drive(so no H:) someone have any thoughts on this

  64. so says

    Is it possible to add two versions of windows 7 on the same usb flash drive? Like x86 and x64, both on same flashdrive? I mean, with some kind of bootmenu… Thanks!

  65. Kyle says

    Hey. Followed every step without any issue but when I try to boot from the USB I the message “BOOTMGR missing” any help would be great

  66. Kyle says

    Hello. Completed every step without issue but when booting from the USB first message I get is BOOTMGR missing.
    Any help would be greatly appreciated.

  68. David says

    This doesn’t work if you booted UEFI, which is the default under all modern computers running Windows 8. This is the source of all the people complaining about “This tool can only be run on systems booted using a PC/AT BIOS” errors.

    The information is helpful, but you should state the issue with Windows 8 at the beginning in order to steer people towards other solutions.

  69. admin says

    @ SolidSonicTH
    Yes, works without any issues for Windows 10 as well. But if you’re are looking for more detailed guide for Windows 10, please use the following guide:

    Works for Windows 10 as well, lol.

    Not that I really had any doubt since things have been pretty standard since Vista.

  71. Adeyemi Oluwaseyi says

    I use the command in step 4 FORMAT FS=NTFS several times and it keeps giving me “100% completed Disk has encountered an error: the parameters is incorrect. see the system Event log for more information”… Please what do I do next or what may be the problem, and what is the solution. Hope to hear from you soon. Thanks

  74. Raza says

    Thanx admin for this informative post. I tried this and made up to a successful boot from flash…but im facing problem during installation of windows…when system gets restarted during windows installation, it starts a fresh installation again. (Procedure of windows installation starts from the beginning) .Need Help on how to get rid of that.
    Regards Raza.

    @ Ken
    Simply mount the ISO file and then use the drive letter of mounted drive. If you’re on Windows 7 or Vista, please check the following guide:

    YES! Excellent fix to my BOOTMGR missing error. I was able to install Windows 7 using a USB flash drive successfully. Thank you!

  82. Chris says

    In step 7, after typing BOOTSECT.EXE /NT60 F: I got “This tool can only be run on systems booted using a PC/AT BIOS. This system was booted using EPI or some other firmware type.”

    Could you please state how to get around this?

    I could see you got the same post earlier this year by Mario

  83. Azhar says

    sir thanks
    this the only method which i have found use full and correct.
    i have installed windows 7 successfully on my Samsung note book.
    again thanks

  87. grendel54 says

    if you are getting “Access is denied” on step 7…you need to run Command Prompt as administrator.

    in windows 7…you can go to your apps…type in cmd right click on command prompt and click run as administrator.

  88. grendel54 says

    I can do everything but when i get to…

    Even though I know something about computers, I didn’t understand any of the sentences in this tutorial. Can anyone help???

  95. Brian Kincaid says

    Even us old school IT Vets can learn a thing or two :) Thanks for the DOS walkthru, big help. Formatting a drive for my son’s laptop and his CD just took a dive. Great work here.

  97. Alexander says

    The bios wouldn’t recognise my USB DVD-drive, so this was a great work-around. Thanks a bunch for the guide. Simple, straight forward and I like that there’s no extra software to download either.

  98. Kiel says

    Thank you, this one works for me, im able to create windows 8.1 usb bootable installation.

    Hi! Thanks for the post!

    In step 7, after typing BOOTSECT.EXE /NT60 F: I got “This tool can only be run on systems booted using a PC/AT BIOS. This system was booted using EPI or some other firmware type.”

    Help please!

  101. Mario says

    thanks for your help now I wonder how to get back to the old situation because i can see usb on my pc

  105. Alexander says

    It’s a very good, simple guide, but there’s something I can’t get right. I’m running a windows 7 32 bit, and I’m just trying to upgrade to a 64 bit. When I type BOOTSECT.EXE /NT60 1:, I get a message saying that the bootsect isn’t compatible with my 32 bit OS. Which is counterproductive because I need to use this to install my 32 bit OS :(. Can anyone help me as to show me what I’m doing wrong?

  106. Robert says

    Thank you for making this guide. Idk why other guides can’t get it right, but yours tells every step very clearly and doesn’t leave anything out. Cheers!

  107. AgedTramp says

    Very useful, very clear.

    David:- copy the whole thing, as in open explorer, click on the dvd drive, click on any file in the right window, hit Ctrl +A, Ctrl +c, move to your pendrive, click on the drive, then Ctrl +V, then wait, and done.

  109. david says

    this is a pretty stupid question but when you say copy the content from the dvd ( in my case an iso file) to the usb…. do i need to copy the whole file or do i need to extract somehow its contents to the usb ? Power iso

    someone answer plz

  111. hugo says

    also, my computer uses UEFI bios but i substitute ntfs for fat32 when formatting, does this play a part at all?

  112. hugo says

    i have no problem creating a bootable USB using part disk and copying bootsect.exe but it still will not boot from start up. I have a iso and the original disk and am unable to perform a clean install. I have used the disk to perform a clean install previously and it worked like a charm, i do not have a optical drive otherwise i would just use that instead.

    If you have any suggestions as to where i could be going wrong?
    i am trying to clean install win7 ultimate on a pc that had win 7 64 previously

  113. NIBIN says

    i lost my existing os and have no cd rom. how to install windows 7 or 8 on my pc from a usb drive. i never have a way to make it as bootable device. can u help??

  114. Alex says

    Great tutorial. Worked like a charm. The only suggestion / comment that I had has already been posted which refers to the formatting of the pen drive. Considering it is an actual pen drive, there is no need to do a FULL format, quick format should work just fine and save some time. But all in all, excellent tutorial! Congrats!

  115. Richard says

    This worked PERFECTLY!!! Thank you so much!!! I tried so many things before and THIS is what worked for me! Thank you Thank You THANK YOU!

  116. Pavel says

    If you have problem like “This tool can only be run on systems booted using a PC/AT BIOS. This system
    was booted using EFI or some other firmware type.” just do full reboot your PC, it should help.

  117. DWalker says

    There is an extra command listed in step 6. Guide says:

    “Step 6: Maximize the minimized Command Prompt in the 4th step.Type the following command now:

    D: CD BOOT and hit enter.Where “D” is your DVD drive letter.

    CD BOOT and hit enter to see the below message.

    Step 7: …”

    The second “CD Boot and hit enter…” is superfluous, I think. Otherwise, great directions.

  118. Ashim says

    Hey.. when I open command port and type DISKPART and hit enter and then type LIST DISK then there was showing only my tow HARD DISK Drive only.. my PAN DRIVE is not showing in the LIST DRIVE. How can I solve it?

  119. jonnie says

    Hey, just about to try this cool guide, but how the heck do you get into the bios or boot options on a sony p-series ? thx

  121. May says

    Reading the tutorials on creating a USB Win 7 repair drive, I thought you might want to add the following some where. Concerning error code 0x80070057 and not being able to restore from a WindowsImageBackup. Most any USB drive method will work for Win 7 as long as you remove the USB flash drive just before the reimaging process starts. Let it find the image and click next. Then remove the flash drive. Once it is restored it will reboot. I downloaded a Win 7 iso from Digital River and used the Microsoft Windows 7 DVD Tool to make mine, but I tried many methods from tutorials and most work if you unplug them as I’ve described. Any repair disk on a DVD will work as a source for needed files as well (You just need to get a decent tutorial online for making the USB bootable.

  125. robert says

    This works fine on older BIOS, but am afraid the EFI version stops it at the last phase. Do you have a version to allow this to work on an EFI BIOS PC (running Win7 Pro 64)

  126. mihkel says

    Someone here mentioned, that a quick format saves your data, deletes only the “mention” of it. Not to pick on anyone, but the difference between a quick and a full format is that when choosing full format, the disk will also be checked for bad sectors, and that is the main reason it takes so much longer than a quick format. All in all, USB keys don’t fail with bad sectors (they, well…just fail), so I really don’t see a reason to do a full format on it. Nevertheless, this tutorial is great. I’ve used it every time when reinstalling windows. I only wonder why it wont stick to me. :)
    This goes to show, that you don’t need additional 3rd party apps all the time.

  127. admin says

    Is your USB drive appearing in Device Manager? If yes, try following the instructions in this guide:
    intowindows.com/fix-missing-drives-in-windows-explorer/

    You could also try to format the drive using diskpart.

  128. ntomi26 says

    I tried like a hundred “solutions” from the web, but onli this one helped me bring an ancient laptop back to life. Thank you so much! You helped me out big time!!! :)

  129. tanuzzo says

    i used this guide and successfully installed windows, but now i would like to use my usb normally again. when i insert it into the pc i can see the usb in computer, but it is shown as hidden and in diskpart it shows that it is 0B. how can i have access to my usb again?

  131. Yvette Faye says

    this was very helpful, and Yes be sure and log into the Command Prompt as Administrator because this makes Step 7 work, used the XCOPY with /E switch to copy the Windows 7 DVD to the USB H: Drive, hope hit makes it work like the DVD for install.

  134. The corrector says

    WARNING: a USB flash drive WILL NOT format in seconds, this guide is wrong. a 16Gb drive will take 45-60 minutes.

  136. Alex says

    If you just change ‘FORMAT FS=NTFS’ to ‘FORMAT FS=NTFS QUICK’ it will do a faster format. meaning it doesn’t destroy all the data, but only the mention of it, so it still will appear formatted (and don’t worry all the old data will just be overwritten)

  140. admin says

    @cysag
    It looks like your USB device is write protected. You need to remove write protection first.

  149. Kexin says

    OK, I have spent some hours to find this out. And I am now sure about two things. (1) All of them who said something like “it works” had a 32 bits version of Window 7. With 64 bits version, you have to take the key off and put it in again. (2) After embedding USB3 drivers (e.g. 6 files from HP’s SP54511, x86 or x64) into boot.wim, this guide works also for USB3 ports (also on none-HP machines). But still 64-bits needs out-and-in manoeuvre, while x86 works just fine.

  150. Kexin says

    Thanks! Very useful guide. The created USB key will actually boot. But Windows 7 installation wants to have some CD/DVD drivers to gain access to this USB key again. If the key was inserted to an USB2 port, I have to cancel the install, remove the key and insert it back again (to the same port or another USB2 port) and try to install once more. If the key was inserted to an USB3 port, I have to change it to an USB2. Was there only me who run into this problem? Is there a way to embed some generic USB3 drivers to the source (now it is on a USB key), so that Windows Install will load them automatically? And I don’t need to change port anymore. What about if I don’t have one USB2 port?

  156. pawan says

    dude help me i don have a cd/dvd writer in my laptop.. how can i do the below step :

    Step 5: Next insert your Windows7/Windows 8 DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).

    Step 6: Maximize the minimized Command Prompt in the 4th step.Type the following command now:

    D: CD BOOT and hit enter.Where “D” is your DVD drive letter.

    CD BOOT and hit enter to see the below message.

    Step 7: Type another command given below to update the USB drive with BOOTMGR compatible code.

    BOOTSECT.EXE /NT60 H:

    14

    Where “H” is your USB drive letter. Once you enter the above command you will see the below message.

    Step 8: Copy your Windows 7 or Windows 8 DVD contents to the USB flash drive.

    please help me ASAP yar.. kinda stuck !!!:(;(

    thanks

  162. Utsav says

    @Gio tis
    Hope you managed to get it done, if not just download a powerISO or any other virtual drive program. set virtual drives to 1. it will appear in your ‘My Computer’. right click on the virtual drive and mount the image you downloaded from TPB.
    Hope it helps.

    @Jone:
    I made the same mistake
    BOOTSECT.EXE /NT60 H:
    here replace H with your USB drive letter.

  163. Remnant says

    great. format fs=ntfs does not take a couple of seconds, it takes OVER 4 HOURS on a 64 gb usb. and you can’t interrupt it after its started without destroying the usb. so much for saving time

  165. Giotis says

    i dont have a DVD with windows on it, i just download them from tpb..
    so in step 5 and above what i can do ??
    just go in step 7 and contineu and paste in USB the contents i download ??

  166. Jone says

    Target volume will be updated with BOOTMGR compatible bootcode.

    What???? Tried this on 2 different usb sticks

  167. Asif says

    Works. You can also use your PC folder if you have windows dumped in any of your machine folder.Just use the boot command in that particular folder.

  170. Darryl says

    To all the chums getting stuck at step 7. I had the same error message as some are getting. (could not open the volume root directory) I noticed the USB drive ‘busy’ LED was blinking, and the icon for the drive was greyed out in Win Explorer. I let it go for an hour, but it was still blinking, so I just pulled the drive and re-inserted it. Icon changed, LED stopped blinking, and I was able to run bootsect.exe successfully.

    If you have an ISO, you can download a freeware tool like Virtual CloneDriver to mount the iso as if it were a cd. Worked for me.

  181. roh says

    Thank you very much! one of the few step-by-step guides where what happens in the screenshots is exactly what follows on your pc, this was very useful and worked perfectly without me having to improvise, simply follow each step exactly and it will work

  188. Mikel says

    I’ve tried a couple of other methods but it did not work out for me well, lot of errors.

    But this worked for me so smooth. I want to thank you for taking time to do a such a clear and fantastic guide. You have helped me and others big time. YOU ARE THE BEST!!

  189. Marvie says

    instead of using DVD, I use the ISO file. Load it in ISOBuster or PowerISO and then select extract contents to….

  191. Martijn says

    Also, why does diskpart do this?
    The ASSIGN command assigns a drive letter that is already in use by a network mapping. Grmbl grmbl, and other noises!

    Solution: manual override :)

    ASSIGN LETTER=X

  192. Martijn says

    FORMAT FS=NTFS QUICK

    Do that instead. It’s been a few times that I accentidally did a full format, and doing that on a USB stick is *NOT* just a few seconds!! Please change this in the guide, dear editors.

  193. Hoai Pham says

    the Format command is very slow. There’s an other way to speed up this command is using quick format option.

    format fs=ntfs quick

  194. Mr Right says

    Titan Uranus, you are special, this guide shows you how to make a bootable USB copy of windows, so in the first place you would need to have the Windows files in order to create the bootable USB. Whether you have the original on CD or have downloaded a copy from the web, without the original files you would not be able to do this. So the moral to the story is, put your brain in gear before you type anything in future because you are only making yourself sound a little dim.

  199. Titan Uranus says

    Nice guide, until step 5 where it requires a CD :) pretty retarded to call it FROM USB then xD

  204. ASEEL says

    Please, i have followed each step and i am sure i did not make any mistakes along the steps.. When i got to Step 7: “Type another command given below to update the USB drive with BOOTMGR compatible code”.

    I typed BOOTSECT.EXE /NT60 G: where (G: represent my USB drive and F is my CD/DVD drive.)

    The error i got after type BOOTSECT.EXE /NT60 G: was (BOOTSECT.EXE was not recognized and a internal or external, operable program or batch file.

  208. Rick Shultz says

    I was fine until like many others I got to the part about inserting the CD. Well, what if you don’t have the CD. Many if not most OEM computers don’t come with a CD and mine is a netbook so there isn’t even a drive, so how about instructions to make the bootable USB from the hard drive itself?

  209. tor erik says

    hey there, looks like an awsome guide, but it is possible to do it without the CD? i bought 32 bit windows 7 ultra, but now i wanna upgrade to 64 bit and i dont have the money to buy it. so i downloaded windows 7 ultimate 64 bit from piratebay, can i just copy the files to the usb or how to do?

  210. littledanniel says

    Thanks for big help. Just one thing, in step5: D:CD BOOT can be just D: — that’s why next step you need CD BOOT.

  211. Ranto says

    Great work Dude!! That works like a charm, very easy and no need to install software. Thanks you very very much

  214. faysal says

    hi, nice work, but its not working for me, i had 2 hard drive 1 is 40 gb and other is 80 gb, both shown after disk part command but i cant see my usb drive in diskpart, i m having 8 gb kingston usb drive, any Solution ?

  216. Adrian says

    The information in this article is excellent. It enabled me to create either a Win-7 or Win-8 bootable SSD drive without any problems. I wish I had read it sooner !!

    Thanks

    when i strart installing it asks me to locate a driver but i don’t have. Pls tell me what to do.

  219. MUHAMMADKHAN says

    LOve it man.. just love it.. U r the best.. and it works it really works…

  220. win64 says

    I had small issue. It was:

    This version of D:\boot\bootsect.exe is not compatible with the version of Windows you’re running. Check your computer’s system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

    I tried to use 64bit windows bootcode from my 32bit windows, but got an error. But i fixed it easily. I simply used 32bit windows to create bootcode and then copied 64bit windows contents on my flashdrive.

    Other than that issue it worked like a charm. Thank you!

  232. Mark says

    Unfortunately this tutorial doesn’t work for me. I followed the steps like explained and did all the commands in the Command Prompt right. But when I try to copy the files from the DVD drive to the USB, I keep getting the following message: “Invalid MS-Dos function.” and it’s about the “the bootsect.exe.mui file”. I also tried with Windows 7 USB/DVD tool, but that also didn’t worked out for me. It kept saying that the selected file was not a valid ISO. I tried with three different ISO files, all home premium 32 bit, and with all the same error. Is there perhaps someone who can help me? I would really appreciate it.

  234. Naeem says

    i am follow all the procedure but when time come to install it will show me that setup was unable to create a new system partition or locate an existing system partition.
    i delete all partition but the problem as same.

  235. Jew says

    Why would you want a bootable USB version if you have the disk in the first place!? got to the step where you ask to pop in the Windows 7 disk WHICH I DONT HAVE since i wanted to boot from USB. FFS Seen you had another guide you ripped off from another site. w/e was dumb

  238. Dullaron says

    Oh you can’t install Windows on a USB hard drive. I tried this way. Other way works.

  241. Paul says

    It would be nice if you mention that a system with 32 or 64 bit computer is required.

  244. Stefan says

    This is not a 100% working guide, because this guide only applies to older computers. Computers with UEFI firmware cannot boot from NTFS volumes, only from FAT12, FAT16, FAT16B and FAT32 volumes.

  246. Herman says

    I tried following your guide and when I plugged the USB into my computer, it either tells me to put in something to boot from or it gives me a message about missing bootmgr.
    Also, FYI, yes, my boot priority is set to my USB drive.

  249. larie says

    this is a good tutorial, but i do have one problem, by selecting partition & creating partition primary am i creating and partitioning on my USB or on my system c. can u explain more about these two commands plz

  250. lolZor says

    Everything worked fine though I had some problems in step 7. But when I decided to skip the CMD format procedure and do it in the GUI (right mouse click on drive, format e.c.t) everything worked fine and I could install Win7 on my Netbook. Thanks a lot for this!

  252. FRANCO says

    You really helped me!
    I have tried other methods but none of them were successful like this one.

    I used deamon tool insted of source dvd drive…

    What is the problem? Anyone help me

  254. thinklinux says

    Hey… Thanks for that post. It’s so easy : ) No more strange programs to make a bootable flash drive!

  255. Asim Ishaq says

    Works perfect. I created many bootable USB using this method, however one thing I noticed that the format from CMD takes a lot of time to complete. Now I do all the steps except format it with windows.

  258. reyhane says

    hi . tnx i have one problem and it is …
    when i type format fs=NTFS it write 0 percent completed
    why ?
    can you help me ?!

  259. Eric says

    Lee, you can extract the contents of your image with WINRAR. Download it, install it, open your image, extract the contents to your usb, then uninstall WINRAR if you wish. Done. :)

  260. gil says

    First of all this is Really a good post, next vitalii don’t worry just try HP Disk Format tool, i hope issue will be fixed and u could format it.

    gil…

  264. Vitalii says

    Hi, I also damaged my flash drive because FORMAT FS=NTFS performs full format. And during it I accidentally press Ctrl+C and after that my flash drive could not be formated by Windows at all.

  265. Tin says

    The only thing I did with this tutorial was fucking up my USB drive I can’t open it now ?

  266. Ryan says

    I guess you did not right click on CMD and run it as Administrator Sir, because I have the same problem like you and try to read again and found out that the problem is just I don`t run it as Administrator don`t try CTRL+SHIFT+ENTER, just right click and run as Administrator

  267. Dan says

    Thanks for this. Worked 100% for me.
    Is there any way to make the USB format procedure into a .bat file? I’m no DOS expert though, maybe this is impossible.

  269. Chwb says

    I followed the instructions exactly, when I change BIOS to boot from USB and restart I get the message NTLDR.exe missing or corrupt?

  270. wesam says

    So thanks for the useful guide and everything.
    Everything worked perfectly but I got to the point where in the end of the windows installation it told me to restart so I had to boot it from windows and not from the usb..
    and when I did, it said it will complete the installation.. it was updating but I didn’t think it would work cause it needed the USB to finish that..
    so it got me an error and asked me to re-do the installation..
    what do I do in this situation ? is there another way to do this.
    thanks in advanced :)

    oh… i managed to change the CD and it went through but this time the error was this:

    Worked perfectly without any problems. Only confusing part was Step 6. I just navigated to the D Drive and ran the CD BOOT from there.

    Thank you for taking the time to write this out.

  274. AgedTramp says

    Wouldn’t using the /Q switch in the ‘format …’ line increase the speed of the format?

    The /Q switch does a Quick format, instead of the full format. It deletes the MBR, then creates a clean one.

  275. arunpradhapsingh says

    hello sir my laptop does’t have CD drive then how i can follow step 5……..pls ans me

  276. Andy says

    It sounds like you are trying to do this from Windows XP. Windows Vista or 7/8 would load diskpart in the same command prompt, as step 4/6 suggests. I’ll go ahead with the assumption that you are using XP.

    If you get access denied, either:
    A) you have some antivirus software or anti-spyware software that is blocking access to the boot sector of the drive
    B) You have a virus or some spyware that is blocking access to the drive
    C) You haven’t loaded the command prompt with admin privileges.

    To rectify option C, Press Winkey + R, then type cmd, and tick the “Run as administrator” checkbox. Then proceed.

  278. Tony says

    Thanks for the great tip and I could successfully make a bootable USB using 8G memory stick I had. I confirmed I could boot and install/recover on my Samsung ATIV 700T.

    Now, I want to save Recovery Image onto a USB stick (the file size is over 40G), so I bought a SanDisk 64G Extreme. I did not want to use two USB sticks, so I followed the step above and went through all steps without any errors like before, but the 64G drive is not recognized as a bootable drive. I tried on my desktop PC and the result is same.

    Help!!!

  281. rhone says

    Thank you for this article. Saved some time and money by not having to install a DVD drive or buy software for USB loaded with bad stuff.

    I wish i had seen this article before wasting time looking for software to do this – one to create ISO, one to mount to USB or one to do both or whatever. What software i needed was confusing. This article cleared all that up in a couple minutes. I researched a couple dozen free versions, trial versions, even paid versions and most of them are reported to have adware, spyware, malware, etc on them.

    I started to use one of my XP machines, the one that had a DVD drive, but soon found this guide doesn’t work on Windows XP.

    I used my Win7 machine to create a bootable USB flash drive to put Win7 on it.

    I missed one little thing somewhere and had to start over.

    I installed Win7 from the USB drive on my other XP machine that did not have a DVD drive.

    Thank you.

  282. paul says

    Hi,

    Worth mentioning that if you are trying to create a boot usb key for a 64 bit o/s from a 32 bit o/s you need to use the 32 bit version of bootsect.exe (from a 32 bit boot dvd). The microsoft Windows 7 USB/DVD Tool will fail in this situation for the same reason (can’t run 64 bit binaries on a 32 bit o/s).

    Hope this helps others who run into this like I did.

    Paul

  283. Indrek says

    Doesnt work for me after i type in the BOOTSECT.EXE /NT60 G: i get error:
    “Could not open the volume root directory. The parameter is incorrect.”

    I did everything exactly like in the guide, only difference is that im not using real dvd, i use mounted image.

    Can any1 tell me whats wrong?
    Thanks

  284. Jørgen says

    Hey Chris

    You have to run the commands from an elevated command prompt.
    Right click command promt and select “Run as administrator”

  285. chris says

    Hey,

    So I completed all the steps and when I get to the end and do bootsect.exe /nt60 I:

    (I have several hard drives so my usb thumb drive im using is the I drive)

    and receive the message:

    Target volume will be updated with BOOTMGR compatible bootcode.

    Could not map drive partitions to the associated volume device objects:
    Access is denied.

    Do you know why I’m being denied?

    Also for a tip, at the very end of the 4th step when you hit exit, this automatically closes the command prompt screen and takes you back to the first command prompt screen. So when you get to step 6, it confused me as this was already my current screen, I did not have to go back to any screen….

    Thanks much,

    Chris

  288. swag says

    after following all the steps and setting up my desktop boot sequence as USB as my first boot device I get this message “BOOT MGR is missing press CTRL+ALT+DEL” pls. help me.. :(

  290. AMS says

    Hi there;
    Can anyone help me… I started following the guide but the command “list disk” gave me Disk 0 only which is obviously my HD. No USB disk listed although it is plugged and seen by windows properly.

  291. Andrei says

    Is it something wrong if I got this message?
    This message I got after step 7.

    Boot sector restoration tools
    Bootsect.exe updates the master boot code for hard disk partitions in order to switch between BOOTMGR and NTDLR. You can use this tool to restore the boot sector on your computer

  292. jean says

    download daemon tools and mount the iso you downloaded onto the virtual cd drive from daemon tools

  294. William says

    If the “FORMAT FS=NTFS” command takes too long for you, you can have it ignore disk Check by using “FORMAT FS=NTFS QUICK” and then it should be just a few seconds for smaller drives.

  296. Dhan says

    hey the thing is that i don’t have CD to boot but i have downloaded windows 7 from torrent and it is in hard drive so how do i do it.?

  300. Igor says

    I’ve found the solution. To all of you who will read this just unplug the USB before the first auto restart and you’re god to go.

  301. Igor says

    First of all very nice trick, saved me a lot of time, but still I’m haveing a one problem. Win are done with install (win7) and it’s time for the first restart, when I restart the whole instalation goes from begining, but it should continue modyfing win to the first start. What am I doing wrong?

    If you could answer in some time i don’t know, very fast i would be very gratefull, I mean very!

    Thanks in advance

  302. Gerhard says

    nice guide man, used it a couple of times. but i do have a question, would this method work with Windows XP also?

    thanks

  304. Adrian says

    “Format process may take few seconds”….how about 15 minutes dude…anyway…thx for this “how to…”

  305. Dushyant Kumar (Maddy) says

    Nice dude. The great thing is there was no need for any third party software to copy windows. I successfully installed windows 8 using this trick and and using the same.

    Thanks a tonn !!!

  309. repair says

    how do you strip dvd down without using another program like win to flash which will undo all of the above steps?

    or am i missing something…i did xp vista and seven before,but these new hp notebooks and netbooks are sometimes weird.like the ahci switch for windows 8

    The mentioned “format fs=ntfs” isn’t going to take a few seconds, instead over 10-20 minutes.

    To do it quicker just type in “format quick fs=ntfs”.

    1) You must right click cmd.exe and click "Run as administrator" or it will fail everytime.

    2) You cannot create a bootable 64bit Windows from within a 32bit Windows.

  315. ihsan says

    actually u must Add EXIT command. and then continue with bootsect.exe /nt60 “drive letter”:

    I tend not to drop a ton of remarks, however i did a
    few searching and wound up here Install Windows 7 From USB.

    And I actually do have a couple of questions for you if it’s allright. Is it simply me or does it look like some of these responses come across like they are coming from brain dead folks? :-P And, if you are writing on other online social sites, I would like to follow everything fresh you have to post. Would you list of the complete urls of all your community pages like your twitter feed, Facebook page or linkedin profile?

  317. Rayolaser says

    I did had the same issue. The solution that worked for me? I forgot to right click the Command prompt icon from windows and select run as Administrator. Issues the same command and it worked fine after that.

  319. Derp says

    I feel like such an idiot..because in step 3 I put a space where it didn’t belong and you made me see that. Thank you!

    I did everything on this article to a T, and when I boot from usb at startup it says windows could not be found and to unplug all hdds that don’t have windows on it. I tried that and it doesn’t work. Any suggestions?

  321. David K says

    I can’t get past step 4 :| It doesn’t recognize the usb. The computer recognizes it, it just doesnt show up in the command prompt. Any suggestions? I’m using windows XP

  323. Stephen says

    I had this problem and the solution was very simple, the bootsect command is case sensitive.

    Make sure you enter it the correct way

    Bootsect.exe /nt60

  324. That guy says

    Did you originally open the command prompt by using Ctrl + Shift + Enter? That causes the command prompt to open with administrator privileges.

  325. Noel McDowell says

    You need to run your CMD window as Administrator, Rick. Do this, close the CMD window and press windows key, All programs (Win vista/7/8), accessories, and right click on the CMD prompt application icon and select “run as administrator” in the menu. Then try starting from step 7 again.

    Hope this helps,

    Rick one method i would try is getting a live linux dvd and boot into it.
    then reformat the usb from there then boot into windows and follow the guide again. that is what i did

  327. Douggiefintry says

    Absolutely brilliant – thanks so such :-)

    Spent hours trying to get WINDOWS 7 USB/DVD DOWNLOAD TOOL to work (it worked fine with a WIN 8 ISO made from original DVD but refuses to accept a WIN 7 ISO made the same way as a valid ISO file).

    This did the trick and got Win 7 back on my Notebook so I could then use the Win 8 Upgrade.

    its too bad method you have to just download windows 7 usb/dvd tool and insert in virtual cd than copy files into usb

  334. Saurabh kumar says

    Instead wasting your time in it… do these simple task:-
    1. Insert the dvd or mount dvd disk image in computer having win7, lets it is H drive.
    2. Insert pen drive and format pen drive with ntfs…suppose it is I drive.
    3. open cmd with run as administrator and type H: and enter then type Cd boot then enter and then bootsect.exe/NT60 I: and enter.
    4. open h drive and copy all of contents and paste in I drive. Thats it.

    Installing Windows 7 or Windows 8 on Lenovo x100e.

    The Lenovo notebook x100e doesn’t have a CD/DVD drive. Therefore you must install windows from a USB flash drive.

    Make a bootable USB using Windows 7 USB/DVD Download tool which also works fine for Windows 8.

    I did have the issue that my usb flash drive as bootable but my Lenovo x100e didn’t boot from the usb flash drive.
    Although I set it to “boot from usb” in the boot menu.
    ´
    After some trying I found out that the bootable USB flash drive must be formatted in FAT32 not NTFS. When your USB flash drive is in FAT32 then installing Windows 8 from a bootable USB is piece of cake.

    I hope that helps one or another!

  385. Maxxim says

    This is an excellent guide, thank you so much!

    I think you should point out that this approach works around a major problem with the native Windows 7 USB Tool. The latter only works with USB drives identified as “removable”. However, a lot of USB hard disks are identified as non-removable due to the Removable Media Bit (RMB) not beeing set correctly. Your approach however works for both removable and non-removable USB devices, therefore it succeeds where the native tools fails.

    Many thanks again!

  390. Abdul Ghaffar Qazi says

    salman you must have at least an image file of windows8 on your hard drive, then you have to mount this image as a virtual dvd rom on your computer by downloading any free software like “magic-disk”. It means you may now continue without DVD rom.

  395. ak says

    Thanks for the guide. This is the most helpful tutorial I found.

    Just a few notes:
    – USB drive will only show up in DISKPART under Vista/7
    – If you’re making a 64-bit Windows Disk from a 32-bit OS, you need the 32-bit version of bootsect

    great guide :-) thanks for this
    you can also use the short terms

    LIS DIS
    SEL DIS X (X being the USB drive letter, seen in list disk command)
    CLEAN
    CRE PAR PRI
    SEL PAR 1
    FORMAT FS=FAT32 QUICK
    or
    FORMAT FS=NTFS QUICK
    ACTIVE
    EXIT

  424. Frank says

    Thanks very much, worked so well I was sitting there thinking “C’mon where’s the problems?”. Just two very minor points; add the QUICK parameter to the FORMAT command to speed it up; The BOOTSECT.EXE must match your existing OS, i.e. 32 or 64bit. Also the laptop I used the bootable USB drive on has a dead DVD drive so I used a second USB drive with the OS files stored on it.

  425. mirza says

    i was at step 4 when my pc got shut down (due power failure), but now my usb drive is stuck. i cant format it because when i try i get msg windows can not perform this task. below usb drive icon NTFS is written. please help

  426. Anthony says

    Thanks so much!! The bootsect.exe portion wasn’t working but then I realized that I didn’t run it as an administrator!

  428. Cor Bryant says

    What the hell? All these years and I’ve had to go through some janky procedures to do this — some of which didn’t work. Good job man! This >IS< the easiest way to achive a bootable installation. Good write up.

    And for those of you trying this with XP. It will not work, not this way.

    Another thing I did was used the 'QUICK' option after the format command. It takes quite awhile to format a 16GB flash drive and I don't think there is any real reason to do a full format when you just cleaned the drive.

  429. Yang Li says

    This is a awesome post. I was trying to reinstall Windows 7 on my laptop Lenovo X61 which has no CD drive. This post really saved my life.

    Thank you very much.

  430. Ryo says

    On the format, you can do a quick format by adding quick to the format command.

    i.e. FORMAT FS=NTFS QUICK

    No need to wait an hour to format a 8GB stick.

  431. viswanath sai says

    It was very nice, but i have small doubts here i hope u’ll clarify my doubts.
    1) Why do we need to use disk part, list disk and all that commands, i think it just converts the flash drive to NTFS file system, Why can’t we do it directly format it to NTFS either it may be quick or normal.
    2) Why do we use only NTFS file format here , Why can’t we use FAT or exFAT.
    3)I have tried this thing with XP but dis doesn’t work, any help how can do it ????

  434. trish says

    i have windows x32 and i want to install x64 and at step 8 i have problem and it says i should use x32 what should i do?

  435. Som says

    I did this even faster by changing the line;

    – FORMAT FS=NTFS, to
    – FORMAT FS=NTFS QUICK

    Formatting takes quite a long time, so I’d recommend trying

  438. jabao_ron says

    On Windows XP, DISKPART doesn’t sees the USB device as a disk. So you cannot create the primary device. Take that into account when you try to do the procedure explained above.

    I’m writing this comment as an add-on or alternative to the main article here. The author of the article or anyone else can feel free to use anything in this comment. I don’t need credit for this comment, you may take it as free information.

    The author’s method for formatting the flash drive seems a bit complicated for the average user, mostly because of the heavy command prompt usage.

    To format your drive just right click your flash drive in My Computer (or just Computer on Windows Vista or later) and go to “Format…” instead of using DISKPART. The result will be the same. In fact, this entire article and be rewritten to use a single call to the command line, that command being:

    D:\BOOT\BOOTSECT.EXE /NT60 H:

    This is something that I’m sure many users would prefer to see, because graphical interfaces are much easier to use.

    Also, here is a very short summary for people using an ISO file instead of a DVD (some people might receive an ISO from their university, or purchase and download the ISO from Microsoft):

    1) Get a flash drive and, if it isn’t already, format it to NTFS. NTFS is required for this to work, and you’ll probably need at least a 4 GB flash drive.
    2) Open the contents of the Windows 7 or 8 ISO file and copy all files to your flash drive. PowerISO or Daemon Tools are two programs that can open an ISO.
    3) Run the following command in Command Prompt, replacing both “H” letters with your flash drive’s letter:
    H:\BOOT\BOOTSECT.EXE /NT60 H:

    If you run into problems with the above steps, remember it’s just a summary and it assumes you’ve already read the main article. I’m posting it to both potentially help users with ISO files, and to help people see the basic steps required. Even if you use a DVD instead of an ISO file, the above summary might be helpful, since only my 2nd step talks about copying files from an ISO.

    buddy i have tried this method 100s of time. each time it worked only difference is i used fat32 file system, which changes the last step.. but today it is not working at all. sop trying ur method now.. hope it works.. usb drive is not at all booting even after changing the boot priority…

  466. JohnH says

    Very nice tutorial.

    I didn’t read all the comments, so this may be a duplicate, but I might suggest that a quick format works just as well and cuts the time way down. (Somebody posted early on that a full format took 40 minutes. I also had to wait a looooong time.)

    Just add a space and the word “quick” after the format command. It will then look like:

    FORMAT FS=NTFS QUICK

    The % counter won’t increment upward, but the format should be finished in less than a minute.

  467. RUBAN says

    If you have an ISO file of Windows 7, use 7-zip or Winzip to extract. To extract, right-click on the ISO file, select 7-zip > Extract option to extract everything to your USB.

    And if you already have extracted files on your hard drive, simply copy all items and then paste them in USB drive.

    Dislike it when walkthroughs won’t take you to the very end.

    @ wirowi
    It seems one or more installation file(s) are corrupted. We suggest you try installing on a virtual machine to make sure that setup files aren’t corrupted.

  486. wirowi says

    I’m so sad. I’ve tried everything to install w7 on my desktop from my USB flash disk. It just doesn’t work. So, I completed all the stepts. I go to bios and make sure the USB is the first boot option. Then I enter windows 7 setup. I select language, time and date format and so on and it starts installing and at 70% in expanding windows files I get this error:
    ‘Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070570’.

    I tried installing from the same usb stick on my laptop and it doesn’t work there either, but the dvd(the exact one I made the usb flash after) boot with no problem. Guess I’ll just have to get a dvd-rw and install normaly from a dvd :(

  488. admin says

    @ MD Yusuf Khan
    Yes, you can create bootable USB even if you have setup files. In the last step, you need to copy all setup files to the USB instead from the DVD.

  490. Md yusuf khan says

    hi…
    pls tell me that if i have no CD drive but i have the whole setup file in my system then how i make my pen drive as bootable… and one thing is that i don’t want to re partition my HD…

    @Chetan, I hope you are not talking a physical HDD ‘D’ drive you partitioned and formatted. If so you lost all the data on it.

    The instructions clearly state to substitute the flash drive number you see using List Disk then Select Disk. If you entered your ‘D’ drive then all is lost.

  525. Chetan says

    If boot wont startup try program galled YUMI(Your Universal Multiboot Installer). YUMI is very ease to use. Install it and add isofile and reformat usb stick with yumi program.

    Yumi work in xp, win7 in linux, and 32 and 64 bit computers. It builds MBR etc.

    I did like this page and it worked on my 64 bit computer, but not in my 32 bit computer. In my 32 bit computer freese on startup and get message “press control alt del”.

    With yumi it worked. google “yumi”.

  563. steve says

    @idress, is ‘d’ your dvd drive letter or is something else? The ‘d’ is just an example.
    Plus the DVD you are using must have a Boot directory on it. If not, the boot images may be in the root directory of the DVD.

    Oh no sir, i am not trying to install windows 7 on my USB, what i am trying to do is, install windows 7 64bit from Usb to my Hard drive. I am currently running Windows 7 32 bit on my hard drive.
    I also tried to use the software which is being given here to download from microsoft, after all the steps it all also stated that your USB was succesfully turned into a bootable flash USB, but when i try to boot it doesnt works, and when i try to run the setup from USB to install it on my hard disk, it does not let me do it.

    My current windows : Win 7 32 bit
    What i wanna do is : Install win 7 64 bit , from USb to my hard disk.
    Problem is: its not letting me, even after following all the steps.
    All the steps followed right with thorough confirmation: YES!
    Please help me. i hope i am clear to u know, for what the problem is, i can provide you a screen shot, if you desire. ty

    I have a netbook Toshiba NB505. The problem was that it has a system corruption where it does not able to boot to the desktop. At first I was trying to restore the OS using the built in recovery and it wasn’t successful. I then tried using the flash drive I made using your guide and still unsuccessful. What do you think would be the problem?

  603. revarcz says

    @admin
    Thanks, I got it right… i have executed the commands as described in your guide and copy the contents of the Windows 7 DVD like I said and it did works… Again, thanks for the successful guide….

    @ Revarcz
    You can copy without the help of Command Prompt as well but make sure you execute all other commands as described in the guide.

  605. revarcz says

    I didn’t quite understand the part where you have to copy the contents of the Windows 7 to the USB drive. Is it has to be done using the command or we drag straight out from the disc to the USB drive? Please help….

    Dear Admin,
    thanks very much for your answer. Yes, I understand now.
    I have a question, though. In step 6, I am in diskpart, and when I type
    [DVD Unit]: CD BOOT
    it only lists all possible diskpart commands. I have mounted the Win7 Iso with UltraIso, and checked the drive letter, but diskpart does not change its prompt to c:\windows\system 32 like in the image you show.
    Can you advise?
    Thanks

  610. admin says

    @javier
    You can mouse the ISO file using VirtualClone Drive (free). When you mount the ISO file, you will see another DVD drive in the Explorer with a drive letter. Let me know if you need more info on this.

  611. Javier says

    Thanks very much for your guide. I would like to ask further: how do you load the Win7 DVD when it is an ISO file in your Hard drive?

    this msg shows for every system.
    what shout i do or is someting missing when i tried to set the usb? plz help me

  618. TheGuru says

    For all you people who get Error while trying to install, try taking out one of your ram slots as sometimes windows 7 doesnt install whilst both DIMM’s are populated.. sounds silly but it works on most occasions.. Also when installing windows 7 on a laptop or pc with 2 hard drives – take the secondary hard drive out first because win7 will install the MBR record not on the primary but on the secondary. Hope this helps…

  619. Simone says

    for the problem:
    “Could not map drive partitions to the associated volume
    device objects: Access is denied.”
    You have to run cmd.exe as Administrator, then execute the istructions

    @Maroon. What do you mean, “other PC”. Did you accidently copy over the bootmgr files from your other computers hard drive to the flash drive? Maybe put those files back.??

  629. MAROON says

    i tried all the steps and all goes well, but when i tried to boot on the other Pc,

    a message appears:

    BOOTMGR is missing
    press ctrl + alt+ delete to restart.

    i restart it but same problem …any body can help please?????? thanks

  630. techgal says

    Awesome. Worked great. Up to this point was trying to get an Acer Aspire One netbook to install a fresh version of Win7 (killing XP). It doesn’t have a internal CD, so using external Sony DVD drive. Kept getting a DVD missing driver error with the install disk. Created the USB install per your directions (from the same DVD I was using to install from external) and it breezed right by that missing driver issue.

    One note – when it goes to restart the Windows installation after the fourth step, you need to remove the USB stick from the computer, else it will try to boot again from it and it looks like it wants to start the installation again. If it does that to you, just turn off the machine, pull the stick and re-start. Windows 7 install will pick up where it left off.

    Terrific, concise directions! Thanks more than I can say!

  631. admin says

    I believe you have an ISO copy of Windows 7 on your netbook. If so, please Virtual Clone Drive software to mount the ISO file as a DVD and then follow the same steps.

  635. cipan says

    for those who are using 32bit(x86) system and would like to install to do this step for win7 64bit, you need to be in a 64bit system to perform the bootsect /nt60 command. else you will received “This version of E:\boot>BOOTSECT /NT60 E: is not compatible with this version of Windows. Check your system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program.” error.

  646. Rachit says

    well i have used a simpler way:-

    format a 4GB USB to NTFS file system and then copy the contents of windows 7 installation disk to pendrive.
    Restart your computer and press F12 for boot menu.
    last select your USB drive in the list and press enter.
    Windows 7 installation begins.

    i have tested it on 7 not 8.

  647. Dave \W/ says

    Thanks great for great fix. It used to be much easier to make a ‘disk’ bootable. I will leave this drive as is permanently for future problems.

  648. Xo3e says

    For the format part since i know it takes a long time to do the full format, heres is the quicker way: FORMAT QUICK FS=NTFS. I don’t know why it says it takes a few seconds when on low specced machines it takes a good hour.

    Hi! Thanks a lot! Gr8 & simple manual!

    — Special note —

    When you try to run bootsect.exe from win7-32bit PC, to create bootusb of win7-64bit, it’s said that you can’t run it, due to some incompatibility of 64bit boot disk. I use 64bit PC to overrun this problem. Beware! :)

    — End of special note —

  662. jay says

    the step format fs=ntfs is working for much time. it took 1 hour 1hr for 35% format. i am using dell inspiron with i3 processor and win7 as os

  663. steve says

    Matt, your simplified steps work perfect, at least for Win7. Thanks!

    Just have to make sure the media you are copying already has the boot manager files in the root directory.

  664. Matt says

    This does work, but there are steps in here that are not needed and there is a method in which you can use any Windows OS.

    Here are the follwing commands, this 100% works and is alot easier.

    Insert flash drive.
    Run cmd as administrator

    In CMD type ;

    DISKPART
    LIST DISK
    SELECT DISK X (X being the USB drive letter, seen in list disk command)
    CLEAN
    CREATE PARTITION PRIMARY
    SELECT PARTITION 1
    FORMAT FS=FAT32 QUICK
    ACTIVE
    EXIT

    your drive is now ready to use, simply copy the contents of your instalation media, or extract an iso file to the usb drive itself. * make sure on the target pc you have USB drive as 1st boot device and this will work for any windows install.

  665. Lupe says

    On step 4 once you select disk 1 and enter ‘clean’ in the command prompt. everything on disk one will be erased correct. Can you get anything back that gets erased?

  667. admin says

    @Shaan23
    Yes, you need do a clean install of Windows 7 64-bit and then install all drivers and software.

  668. shaan23 says

    hello, admin, ok my system has been running on 32-bit,Windows 7 Home Premium, 2gb RAM, which i want to upgrade to possibly 8gb, so based on my research 32-bit(MAX.3.5GB) doesn’t actually utilize all of ehm, this leaves me to upgrade to 64-bit, could i? if possible, then do i need to separately install all the drivers & stuff by myself, or is it when i install the windows Ultimate 64, has all the drivers, except all the software of course that i need to install form scratch, i don’t know much about drivers, :(

  669. admin says

    Where would you like to add pictures? If you meant on the bootable USB drive, yes, you can create a new folder and then place the pictures in that folder. But if you are looking to add new wallpapers and themes to the Windows setup, you should check out our intowindows.com/how-to-include-new-gadgets-themes-wallpapers-and-screensavers-in-windows-7-setup-iso-file/ guide.

  670. C. K. says

    Thank you, it works like a charm! One question though.
    Can I add an extra folder with some irrelevant files?
    For example, can I add a folder with pictures etc.?
    Has anyone tried it?
    Thank you.

  672. geoffrey says

    hey thanks for the guide but i just had a problem with step 7
    i didnt get the exact message that appeared i got this

    Drive E: maps to volume \\?\volume{4cefea49-42b9-11e1-b384-806e6f6e6963}.
    This volume does not appear to connect to any disk partitions. Volume bootcode is always unused in the absence of associated partitions.

    what should i do?

  673. SAYR says

    FOR WINDOWS XP THE PROPER COMAND IS BOOTSECT.EXE /NT52 X: (WARE X THE USB DRIVE) HOPE THIS INFO HELPS

  674. admin says

    @ Navin
    Performing a full format should bring back the USB drive to normal state.

  675. Dinesh Raja says

    HI,i have installed backtrack5 R2 (64-bit)linux os in my hard disk as “side by side”along with my windows7 now i want to uninstall bactrack from my hard disk..but i dont know in which block it has been installed…but among my 5 partitions 2 partitions F: and H: some total of 20 GB is missing..in those drives i am able to see an file bootsqm Video CD movie file in both F:&H: drives..please give complete step by step procedure to uninstall backtrack from my hard disk..

  680. Windows 7 USB Instal says

    Thanks for the great tutorial. I would definitely give it a try as I think its much easier and quicker than using Windows 7 DVD.

  681. Nero says

    Thank you for this! Everything works smoothly. I just hope that you can format the usb faster. Cheers!

  684. Carlos says

    Hi!

    First of all, this tutorial is great and I just loved it!

    Second of all, I was wondering if it’s possible to use this method with windows XP? I haven’t been able to so far, I’ve tried formatting with ntfs and using /nt60 with bootsect, and tried formatting with fat and using /nt52 with bootsect, but when i try to boot it keeps saying either bootmgr or ntldr is missing, am I doing something wrong?

    Thanks!

  685. adi says

    hi,

    i tried the way you listed on this webpage but when i go to install the os from the pendrive it says BOOTMCG not found or missing or something like that. i tried each and every step . please help me its iregunt. i think it might be late if you answer it afterwards but still i need a solution.

    thank you in advance

  686. echenze says

    I have written extensively about this and I can confirm that the above method works 100%.

  688. Ahmed Yahia Sebeka says

    Thanks so much for these awesome information
    i tried this way and it really works with me when i was running windows seven

    but if i have running windows xp list disk dose not appear disk 1 :(

    so is any other method to make a windows 7 bootable usb bt with running xp system ??

  689. Kai says

    This is by far the best guide I’ve read. It has simple yet detailed explanation, but the “formatting might take a few seconds” part.. makes me mad, I am at 10% right now.. and its already been 5 minutes.. damn USB. Anyway, I will post again when I get to try it out.

  691. admin says

    @Krish
    Use a free tool named Windows Bootable Image Creator. Google it. It’s free and does the job for you.

  692. Krish says

    Very useful guidance indeed but I have a win8 OS file extracted from image and I want to reconvert that extracted file to bootable image which could be burnt in the DVD. As I lost the image file.. Is there any mechanism to do so?

    I need to format my Computer soon… Please RSVP this post.

  693. listoss says

    Well if you run cmd from the run box

    ctr + shift + enter

    doesn’t seem to work. your

    bootsect.exe /nt60 g:

    comand would be denied as admin so kindly run you ctr+shift+enter after typing cmd from the search programs text box. thanks

  694. Kael says

    This procedure worked perfectly. The key is to follow the instructions exactly. No skipping. Thanks very much.

  696. Vadim says

    Is that possible to install windows 7 on usb,because windows during the installation not letting me to choose to install to external location like another usb ?

  697. MissMaru says

    I’m having a small issue with the guide, my laptop restarted overnight after “format fs=ntfs”, but before “assign”, and if i redo the steps now he will not select partition 1 anymore even though it is in the partition list.

    I tried reformatting the USB through windows and redo all from the start, but it seems the partition is still there, and so i cannot create partition primary again, cause there’s not enough space.

    Is there any way around this or should i find a different USB?

  698. gerald says

    good day!
    please help! i did the first and second step, but it seems that my removable 8 gig doesnt appear on the list disk command…. what should i do with this…..

  701. admin says

    @Liam
    Just extract the ISO file contents using WinRAR, WinZip or 7-Zip software to the USB.

  703. Liam says

    Hi,
    I have a simplistic question. how is the ISO file copied over to the USB? is it simply drag & drop or use the command prompt to copy it? could you please outline these steps. everything went fine upto this point.
    Thank you for this post, I know it will work for me and bring my Toshiba back to life again.

  709. bhargav says

    i understood but not proper…. so can u make a video and upload in youtube?
    i have windows 8 in my usb { image file } so i am not getting idea to install it so wt to do….. please help me…..

  713. James says

    @Andy

    That error means something is trying to format the drive already. Either wait until it is done or reboot and try again.

    It also helps(is quicker) to use the command:
    FORMAT FS=NTFS QUICK

    That command does a quick format which takes significantly less time.

    @Sevs
    Decompress the iso file in a folder on your C Drive, so the directory will be C:\Win7\(winrar will do this) and then instead of :
    cd boot
    bootsect.exe

    Run this:C:\Win7\Boot\bootsect.exe H:(where H: is your drive letter for the USB)

  714. VIJAY says

    I have tried this upto 4 step,but iam getting error there.so i withdraw my plan to install os from usb.and when i tried to format the usb it was showinng the error that ‘windows cannot format the drive’.please help me in formatting my usb .it very important for me to have my usb back.so please help me.

  717. Andy says

    Hi there,

    i get this error ‘ a concurrent second call is made on an object before the first is completed’

    i have used your guide many times before and it has always worked. could anyone please help with this error?
    Thanks heaps.

  718. sevs says

    Umm… Is there any alternative to step 5? I don’t have my OS on a disk, neither do I have any disk drive on my laptop. I have the OS as an ISO file on my computer. :)

  719. saroj kumar says

    @Rex
    Start the command prompt with administrator rights.
    That fixed the problem on my PC.

  745. Jeroen says

    Wow the extra step described here @ 6 and 7 was REALLY necessary to got my USB working otherwise I kept getting these annoying “No Device Driver Error” error.
    Was installing Windows 2008 server.

    THANKS MAN!!!!

    Why isnt Microsoft aware of this???

  746. Rex says

    I know Microsoft is the copyright holder of Windows and everything that comes with it. I have added watermark to prevent other spam sites from using my pictures.

  749. Max says

    You don’t mention ‘Microsoft Windows’ as a requirement – ie you have to already have a copy of Microsoft Windows installed on your computer in order even try this. I only have the iso files for Microsoft Windows 7 (and lang pack) – my computer is running Ubuntu (or no OS at all, of course).

  751. xnamkcor says

    Exactly what part of those pictures validates the use of the Copyright symbol? Do you own copyright on MS-Dos or Command Prompt? Do you own copyright on the process of formatting a drive?

    Did you know it is illegal to claim copyright of something you have no rights to?

  754. Justin says

    Honestly, I thought this absolutely amazing! I have searched high and low, most sites want to install software to apparently do what you instructed, while saving a minute or two, which also lead to an array of annoyances. Thank you for the input.

  756. rete says

    Thanks! Almost perfect guide. This works flawlessly, but all little boys and girls should be told that they are going to have driver instalation problems in very begining of w7 instalation if they use usb3 port instead usb 2. i had this gaind problem when i was using usb 3 port: A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert it now. Note: If the Windows Installation media is in the Cd/DVD drive, you can safely remove it for this step” After i changed my usb stick to usb 3 port instalation works just fine. =)

  757. JT says

    @DanielF

    Does your thumb drive or SD card have a ‘write protect’ switch on it? If not, chances are your card/drive is dead – most of the time the ability to write dies first, so you can read the contents of a drive, but not write to it. I would try another thumb drive to see if the problem persists across devices.

  758. Tekola says

    Hello Guys…How r u!
    When I make ready for My USB to be bootable I have type this code:

  759. deBoer says

    I see a lot of complaints, but I just want to say that it works perfect. I used it several times without any problems… and I’m not an IT-expert! Many thanks for this tutorial!

  760. rppp says

    It does not work in xp.
    yor title is misleading twat.
    i am using xp to create a bootable usb to install win7.
    twat!

  762. PREET says

    leave that crazy method its really confused one

    to format a usb in NTFS
    just simply go to your device manager look out for your usb check its properties and go to policies tab than check the optimize for performance button after that format usb in NTFS. USING NORMAL FORMAT METHOD.

  764. BarbaricFellow says

    THX for this clear list.I agree there are a lot of non working “manuals”on the net.I also tried the “Windows usb/dvd download tool” but it wont show my USB ext.hard disk in the drop down box.

    I have a question.

    I have a 1 TB USB ext. disk connected to my PC, but I also have a 1 TB hard disk inside the PC I am working on.
    And I can’t tell which is which using disk part.
    Both look identical showing as 931 GB disks with no empty space. It might be a stupid question but I really cant find the answer.

    How do I identify(command)hard disks inside disk part?

    THX in advance.

    Hi, great article, very helpfull!!! I had win xp on my pc at home and had trouble with cd rom as it didnt read any cds so i couldnt rewrite the windows. This guide solved my problem. The only thing id like to add is that it takes ages if you are formating a 64gb usb.

    Thanks very much!

  777. JAMES says

    Used this on a linux machine running Virtual Box – when I gave the FORMAT FS=NTSF command it gave a virtual disk manager error. Did the rest of the steps and exited DISKPART, then formatted the drive through windows explorer (NTSF quick format). Worked great. Thanks, the only way to install on my netbook.

  778. Matthew says

    An oversight by Microsoft ensured that I can’t use a 64bit install DVD on a 32bit system without booting from the DVD. Part of this oversight also prevented the DVDs from being able to boot AND their process for making a 64bit bootable flashdrive doesn’t work on a 32bit system. Your explanation for how to make a bootable flashdrive allowed my to use the 32bit bootsect.exe from the 32bit DVD to turn my nook into a bootable drive with the 64bit install software. My solution is jury-rig, but your explanation was a fine piece of work! Bravo!

  780. lokster says

    works! for sony viao on windows 64bit :D thank you! even though this article is a few years old still works on 2011 models!

  781. ujjwal says

    the method u explained worked properly..but when the windows installs and it shows windows restarting in 15 seconds then when restarts windows 7 load as usual and itz wriiten setup is updating registry then setup is starting services then completing installation tier shows an error…i think in that part pendrive doesn’t load files..!

  782. Julian Luna says

    Didn’t quite work, as I was using a netbook without CD case… the netbook was believing it was a CD, needed to boot the usb with usb booting with the universal usb installer… I don’t really know what happened, what I can guess is that the Netbook was believing to have a Cd inside since it started to ask me to insert a volume with the CD/DVD device’s drivers

  784. Arsh says

    nice tutorial my cd drive got damaged and i could not find any solution until i chked ur article it worked out for me….thanks for sharing this useful information

  786. Bill says

    I keep hitting this wall….

    “The system cannot execute the specified program.”

    I have nothing browsed the web, have nothing for troubleshooting. . .

  788. Martin says

    I have the same problem as Daryl over me here, I used exit to get of the “Diskpart” part of the guide.

    Now my External drive dossn’t have an assigned letter, It dossn’t let me assign a letter and it dossn’t show up in “My computer”

    I used a program called “USBDeview” and I could see that the External drive was infact still connected, but diddn’t have an assigned drive letter nor could i assign one.

    My question here I guess is: “How do i “Recover” the drive and after doing that do i have to format it and all again?”

    Because that took 5-6 hours on my 500gb drive on this shitty pc, and would just seem like a waste of time.
    Therefore if you cannot help me with this I’m off to go buy some fucking CD-R’s and do it the old way ;)

  789. stephanie says

    I have windows xp on my netbook and i would like to install windows 7 instead but I do not have a slot for CD’s since it is a netbook. Can I install windows 7 from a pen drive and do i first have to remove windows xp and then install windows vista?

  790. Daryl says

    i did on ‘exit’ as the last on step 4 and it did close the cmd. i am using virtual machine for win7 installer. as i go on step 6 it says ‘the system could not find the path specified’

    and my flash disk was wasted.. can my flash disk still be recovered? how?

  795. Mark Stewart says

    This is incorrect information for those using SSD SATA for the operatiing system (Dell 2012). Must use CLEAN ALL, not CLEAN. BTW: CLEAN ALL will not run from USB device, so unable to properly format SSD to install Windows. E.g., any registry problems will simply pick upo where they left off. Sorry folks. Win 8 may, “may” resolve.

  804. brittany says

    Here is a simple way to do it, no typing in cmd needed:

    Acquire Windows 7 .iso (do not unzip)

    Get an empty USB flash drive with 8GB+ space

    Format the drive to NTFS if it’s not already (Start -> Computer -> right click the drive -> Format… -> select NTFS, uncheck “quick format”)

    Google “Windows 7 USB/DVD Download Tool” and download from the first link, microsoft store

    Install, open and follow directions to make a bootable USB.

    @ Erik Karisson

    It’s simple. If you are using a flash drive (they are mostly small thumb drives with 4, 8, 16, or 32 GB capacity), then select USB FDD. FDD If you are using an external hard drive, select USB HDD.

  807. mn says

    Very good guide. Thanks. Just used it now.
    One thing to note, though. In diskpart I used “format fs=ntfs quick”.
    I have a 16gb stick and it took way too much to fully format it. A quick format took only a few seconds indeed.

  808. Erik Karlsson says

    I see atleast 3 people asking about which usb *** to use at boot sequence selection…
    I have the same problem
    I’ve got
    usb cd rom
    usb zip
    usb hdd
    usb fdd
    to choose from… none of the other atleast 3 people got any answer…

  810. Huzi says

    A little thing i ran into is that if it won’t boot from the USB (in my case my Acer Aspire One ZG5 just beeped constantly) try another usb slot. If anyone has a ZG5 (AOA-150) try the slot on the right closest to the front.

    These instructions are like a gift from the heavens! I got to “permission denied” when running bootsect.exe, but just read the other comments above to get past that roadblock.

    Now I’ve got XP and 7 running on my netbook… ohhh, it’s a good day!

  830. Spyder says

    Excellent tutorial, thanks
    Possibly worth adding that you can speed up the format process by typing “FORMAT FS=NTFS QUICK” at Step 4

  831. eh? says

    Should you also copy over the auto run from the windows disc? It asked me if i wanted to keep, replace, or use both auto-runs.

    I didn’t know an auto-run was already created on the USB drive but I opted to keep the one on the USB drive and it seemed to work. Would it not work if i had used the auto-run file from the windows disc?

  834. hhgygy says

    This one really works.
    If you get the message:

    BOOTMGR not found. Press ctrl alt dlt to restart

    try to make the bootsect.exe command with the /force tag
    That’s what helped in my case.

    Thanks for the great tutorial

  851. que says

    I’ve tried this 3 times now, and only get as far as formating to 100% complete, but then it never returns to say “Diskpart successfully formated the volume”, nor does it return to a prompt that I can type further commands.

    I’ve tried searching through all these responces to find an answer, but I’m just not seeing one.

    Thanks for your help

    Excellent guide, thanks.
    You can use daemon tools to mount a disc image of OS and then use the drive letter it assigns as your DVD drive.

  863. ieee488 says

    Thanks!

    Worked for me with a Dell Precision M6300.

    My 8GB USB stick took more than a few seconds to format in step #4. More like minutes. :)

    Also, in step #8, typing ‘robocopy D:\ H:\ /MIR’ in the command prompt box worked for me.

  864. anvt says

  870. azrul zz says

    Help!! please help ..

    Master, I have problems after doing these four parts. FORMAT FS = NTFS (Formats the process may take several seconds) at first it went well up to 20 per cent, after that it turned to 0 per cent to wait too long. So I did re-from the first part, and it does not run again. So how to return the flash drive to the original as not doing the things above?
    Please, I hope the Master can help my problem.

  873. Jami says

    The shortcut version:
    1. Format your USB to NTFS using the Windows GUI and keep it plugged in
    2. Open your iso using MagicISO or some other app and extract boot/bootsect.exe
    3. Run bootsect.exe /nt60 :
    4. Copy all contents of iso to your USB

  874. JEMAI says

  888. mohammad says

    Hey guys,
    It also work fine with me,just a few tips that already said above.
    1.open cmd in admin mode only,if dont ur access will be denied.
    2.if you are running win 32 bit(x86) and wants to install a 64bit(x64)windows you will have a problem.you should find a win 32bit and try to update the USB drive with BOOTMGR compatible code with that dvd.after that you can put your win64bit files on USB and change the boot priority at the BIOS to USB from the HDD or CD ROM drive.
    notice that you need to change this priority after copying win files into HDD to continue installing from HDD.

  890. QT says

    Hi BATZZZ19,

    To create 64BIT O.S. to USB flash disk, you need to install 64 bit O.S. to your platform and then typing the ‘BOOTSECT.EXE /NT60 E:’ command line with cmd prompt under 64 bit O.S.

    Best regards,
    Tim

  891. QT says

    Hi sir,
    thanks for your share.but the ‘FORMAT FS=NTFS’command line just to install legacy Win7 O.S. only. It can’t install the UEFI Win7 O.S with Win7 64bit DVD Disc.

    You can changed the command line like as ‘FORMAT QUICK FS=FAT32’ to format the USB flash disk.

    Thanks!

    Tim.

  892. BATZZZ19 says

    WHEN I PUT THE CD IN MY DRIVE

    AND START A NEW PAGE OF CMD WITH ADMINISTRATOR
    THEN I PUT D: CD BOOT AND CD BOOT THEN
    BOOTSECT.EXE /NT60 E: FOR MY FLASH I GET A MESSAGE
    SAYING

    This version of D:\bootsect.exe is not compatible with the version of Windows you’re running. Check your computer’s system information to see wheter you need x86 (32-bit) or x64 (64-bit) version of the program, and then contact the sofware publisher.

    so i was guessing i need to do the setup of cmd from a x64 bit computer to make my flash drive get the info from cd x64 to the flash drive

    but im clueless now, since i dont think that matters since it didn’t read the disk yet, any suggestions?

    Great!!
    I had tried multiple instructions with all failures. This worked perfect and I took my all versions image and it worked so that I could choose from all versions of either 32 bit and 64bit versions. Now all I would like to do is include a SP1 slipstreamed onto the flash drive and I would be really happy:)) Any suggestions to being able to modify configuration for a slipstream update?

    The thumb drives are no longer recognised. It’s no big deal as I just returned one of them to Best Buy. I would really like to know how to re-install windows on my netbook though so I’m wondering is there’s any work-around to the clean process. Or if there’s some other way of formatting the thumb drive for the installation process.

    Thanks for the help.

    Is it ok if my ext hdd has other content?will it be erased or be affected if I will follow your process?

  1007. Ram says

    I tried using this and it worked. But when the setup is restarting the system, it again loads windows 7 and installs a copy again. The setup isn’t getting completed.

  1008. Rudi says

    Please note that Windows 7 setup doesn’t support USB 3.0 device to boot from. This causes a error during installation that the installer needs drivers. Very simple solution is to put the USB stick into a USB 2.0 port!

    Thanks for this guide, works perfect for me!

  1009. say says

    hello.

    i just have one question:
    after formatting the usb, and i don’t have windows 7 installed in cd but i have a copy of windows 7 activator.

    will i just send a copy of windows 7 on my reformatted usb?

    thanks a lot and god bless . ..

  1010. Lee says

    If you’re having trouble finding your disk in list disk you can just type “select volume D:” for example (where D: is the drive letter of your usb). Also for the format selection you can also type FORMAT FS=NTFS QUICK so the format is a quick format rather than a 5-10 minute one.

    Don’t bother reading those computer nerd guides that never works. After spending hours of reading similar guides, i finally saw someone in the comments field mentioning the program win2flash, that made it work in a few seconds!

    *** USE Win2Flash (if you want to save time and troubles) ***

  1016. Brandon says

    okay i did every ting step by step and i still get when i put it into my laptop boot manager missing :/ any suggestions?

  1018. Mikey says

    p.s. Aside from the above mentioned bug, great article. I didn’t know you could do all this with just command line tools :)

  1019. Mikey says

    As other have said above me (#286 for one), you don’t need to type “D: CD BOOT” and then “CD BOOT” the first command “D:” and then the second command “CD BOOT” is fine. Anything after the space in the “D:” command was ignored. All you are doing is navigating the command prompt to “D:\BOOT”. That’s just how the command line works.

  1021. mohammad says

    its very slow format i think that will take a days for formating my flash only

    Thanks anyway for shared information

  1022. DarthZelda says

    So… I got through the guide splendidly, the PC booted, but the data were somehow corrupt, so the installation couldn’t get to an end. But when I inserted the stick and wanted to rewrite the data, so I could do all that again, Win just couldn’t find it. No trace of inserting anywhere. Anyone any hints? I never heard about making a brick out of USB, but I might have just done that xD

    Cheers,

    My system copy installation files and extract files and restarts and after that again and again system restarts

  1028. eggsas says

    Striky just change your bios on restart to start hard drive before usb.
    It worked perfectly for me…

  1029. green house says

    Hi there i have done this and put my USB in and it sarted to take me throgh the set up process, but the computer is then asking me for the drivers. The drivers are on a seperate disk and i have no idea what drivers it would need etc. can you please help me??

  1031. lui says

    hey dude, nice guide.. now i can use my usb as a primary boot device cause my netbook doesnt have a cd/dvdrom.

  1034. Nik says

    Can I install windows 7 64bit version on a windows 7 32 bit version? if yes… then how can I do this?

    thnx =)

  1036. Striky says

    Hi there thank you for the great guide, it worked well!!

    ButI do face some weirdo problem here. I am installing Win7 64bits and the install will require a reboot. At the beginning usually we press any key to enter the windows setup but after the reboot it is not required.

    However by using pendrive as bootable driver the “press any key to continue” screen doesn’t appear anymore and it keep self entering the setup and stopped me from completing the setup…anyone have clue on this problem?

  1039. JP says

    Instead of using format fs=ntfs use
    format quick fs=ntfs

    This will take a few seconds, where just format can take up to a few minutes depending on the USB drive.

    I am stuck at part 6. when in CMD entering D:CD BOOT IT TELLS ME D:CD is not a recognized command so I entered D: to bring me into D: and entered CD BOOT that brought me to D:\Boot> after entering BOOTSECT.EXE /NT60 G it says that is not recognized as an internal or external command, operable program or batch file. Can anyone help me navigate around this problem?

  1048. failmatic says

    This guide is terrific. I’ve been using this for years. The directions are clear and concise. If you cant follow it, perhaps, you shouldn’t be installing windows via usb and go grab yourself an external dvd drive.

  1049. mayank says

    Hey some one pease help me

  1052. Tom says

    Hey

    Firstly to the author of this article, this was terrific. A fantastic guide with very clear instructions. Thanks very much for this.

    Secondly to Jeff; you don’t need to create a folder. After following the instructions set out here, make sure that there is nothing on the USB drive and then copy the contents of the windows disk (in their entirety) onto the drive. Make sure that the BIOS loads from the drive first, or press F12 during boot, and you’re set.

    Tom

  1053. LEKA says

  1054. jeff says

    hi there!

    this is really great, i just have 1 question though
    when you Copy your Windows 7/Vista DVD contents to the USB flash drive, do you need to create a folder first or just copy all the files to the USB.

    also does it matter if the windows 7 is in .iso format? or you need to extract all files first and then copy to USB? thank you so much!

  1055. jayvcc says

    thanks tweak it works smoothly on windows 7 this really help a lot. very detailed on explanations and job well done. =)

  1063. hringriin says

    Hi …

    Well, it actually worked perfectly according to my Windows installation but in “damaged” my usb device in some kind.
    I usually use that one for having live Linux-Images handy, created by “UNIVERSAL-USB-INSTALLER” from pendrivelinux.com …
    The thing now is, that it is not possible for me to get that working again. I think this is caused by the action of BOOTSECT.EXE … Is there any possibility to undo the changes bootsect.exe has made? I’d be very glad, if you can help me. I will also write a more detailed description if needed.

    Regards
    hringriin

    Cool!

  1069. Devang Vyas says

    Yep. Worked fine for windows 7. Good technique without using any kinda software. Thanx for d info. :D

  1071. John V says

    For anyone having problems with the initial setup starting again from scratch when the computer restarts, it isn’t necessary to remove the USB drive at any point.

    Simply monitor the installation process closely and when the computer restarts for the first time, re-enter BIOS immediately and change the boot device priority so that the (non-USB) hard drive is the first boot device. Save settings and exit BIOS.

    This only needs to be done once and the rest of the installation will complete successfully, regardless of the number of restarts.

  1077. martin says

    i got same problem like few ppl here which someone described like this

    “Here is the message after typing BOOTSECT.EXE /NT60 H:
    “This version of F:boot\bootsect.exe is not compatible with the version of Windows you’re running. Check your computer’s system information to see whether you need a X86 (32-Bit) or X64(64-Bit) version of the program, and then contact the software publisher. ”

    I SOLVED IT

    just unomounted the iso from virtual drive and did all the steps again..
    BUT I found out that i mounted wrong file to virtual drive!
    this is why ppl got this problem
    just mount the instalation of w7 in the drive. do this all steps and it will work for sure!
    good luck

  1078. chad says

    It worked. Thanks for the article. 5 stars on the clarity, compare your solution to others, refer to a simpler soluiton for less technical users, and make it #1 rank on search engine.

  1083. iqbal says

    Thanks a lot !! it worked just fine on the second attempt…Very useful..keep up the good work :D

  1084. Steve Ollis says

    Thanks for this. The DVD drive in my kid’s PC died just before they managed to destroy the XP install that was on there. I was going to have to rat a DVD from another machine until I found this article.

  1086. DK says

    Ben… try this…

    Type “G:” (g being the flash drive and with out the quotations) Then press -Enter-

    xcopy h:\*.* /a /e /k (H: being the drive where your windows 7 disk is)
    Then press -Enter-

  1088. Benjamin says

    Just a notice. I downloaded a fresh copy of Vista, and i used daemon tools to mount the iso file. And everything worked 100%.. GL, and great guide, best out there, Would be nice with a guide for XP too :)

  1089. Tony says

    I have a question why doesn’t Windows Copying 100% all files
    it is just copying 10% the files ? please answer

  1091. pherenika says

    On windows 7 removable drives will not appear in the list of disks. If your usb is not showing up in the list of disks, instead of LIST DISK and SELECT DISK 1, type LIST VOLUME and SELECT VOLUME 1.

  1092. Troy says

    Followed to the letter, multiple times. Doesn’t work for me. Says bootmngr is missing, and yes USB is set as primary boot drive. Help?

  1095. shyam says

    I know very well that one windows 7/xp/vista in one bootable pen drive but i don’t know that how to creat Bootable flash/pen drive of Windows 7, Vista, or XP in one pen/flash drive please help me

  1096. GCC1401 says

    For those who got the message “COULD NOT FIND MAP DRIVE PARTITION TO THE ASSOCIATED VOLUME DEVICE OBJECT:
    ACCESS IS DENIED” you did not run cmd as administrator that is why the access is denied. So, close de de cmd and open it as describe in step 2:

    *Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.

  1097. MouZ says

    1. My disk no. of USB flash drive is disk 2. Do i need to type SELECT PARTITION 1 or 2 in my case?

    2. My CD-ROM and DVD-ROM are not working, it don’t detect any CD or DVD. Everything went smooth till i typed F: CD BOOT (F is my DVD RW drive). The error comes: “The device is not ready”. What should i do now??

  1099. MouZ says

    M gonna try this right now. My cd/dvd-rom are not working since 2 months. I thought i wont be able to format until i get it right.. lets see if it works:-)

  1102. Patrick says

    Why not “show hidden folders and files” in folder options and open the windows 7 disc and copy all the files to a flash drive. works for me 100% of the time

  1103. yusri says

    my problem is,
    ‘BOOTSECT.EXE’ is not recognized as an internal or external command operable program or batch file.

    what i need to do?

  1105. Jude says

    I had follow all your instruction and I got it all smooth. But when I tried to use my USB to boot my Acer 4530, I got the message BOOT MGR MISSING. What’s wrong?

  1106. Arjen says

    Hmz, you can skip the step with Diskpart

    mostly because it takes too long (16gb stick)

    You can just reformat it quickly into NTFS format.

    then do the step that comes after Diskpart.

    Works like a charm aswell.

  1107. Shaun says

    Thankyou, after running into the problem of the windows 7 installation hanging when it expands files when i used the dvd was doing my head in, then using this method and booting the setup via usb, made it work like a charm

  1108. vinay says

    ihave a doubt in the 8th step,where u say to copy the windows files to usb.there what’s copying,does it mean to copy image file?.

  1113. Aakash says

    Hey,

    I tried doing this on my external HDD and it didn’t work. So I used a USB Flash Drive and it worked great. But now when I try to use my External HDD, it won’t work at all. Any help?

    Thanks.

  1114. Emirates Skeptron says

    Please see below, what’s wrong? =(

    ———————————————————X:\BOOT>BOOTSECT.EXE /NT60 M:
    Target volumes will be updated with BOOTMGR compatible bootcode.

    M: (\\?\Volume{41bc0891-3a3e-11e0-92ec-1c6f6590ed84})

    Updated NTFS filesystem bootcode. The update may be unreliable since the
    volume could not be locked during the update:
    Access is denied.

    Bootcode was successfully updated on all targeted volumes.

    X:\BOOT>

  1115. eru88 says

    I did everything but when i try to install the operating system it says
    Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007045D

    I try deleting and saving the files from the dvd again to the usb but the same thing happen. I am mounting the iso and saving those files, does it not work like that?

  1116. norbeey says

    All the steps went fine and I have set the removables to the 1st place at the boot priority order but still nothing happens. Why?

  1117. Mike says

    Worked like a charm! I was having network connection difficulties on my HP mini 210. It would connect wireless for about 15 minutes then drop and not come back. HP determined that it might be a windows issue and wanted me to reinstall Windows 7 Starter with their USB drive. Rather than wait over 5 days for the drive, I followed these steps (very clear btw) and it booted right into the reinstall and it kicked off just fine. Now I can put a fresh install of 7 Ultimate on and see if that fixes it. Thanks!

  1118. boat parts says

    hi,Thanks to you for sharing this.Actually my DVD drive was not working and i was not getting any way to install my new copy of windows so i copy all my data in my USB drive attached with other desktop machine and by using this process i installed windows on my laptop.It is really an amazing way for installation.

  1119. krisna says

    ur guide is almost done. but at the end part i did format the “c” drive and click “NEXT” button.so its display a error massage that is “setup was unable to create a new system partition Or locate an existing system partition.see the setup log files for more information”.
    so plz rly to me.thanks to u

  1123. Simon the Pieman says

    This is awesome, My DVD drive on my laptop allowed me to format my hardrive before trying (and failing) to install Windows 7. I have struggled for hours to get my drive to read the DVD correctly and install an operating system to no avail. This guide has basically turned my laptop from a paperweight with no OS to a fully functioning Windows 7 machine once again. Cant thank you and the work you have done on publishing this enough, very much appreciated !

  1124. Mostafa says

    you said Format process may take few seconds ! but it take few hours for me ! why ?
    thanks

  1125. paul says

    Thank you so so much!

    I was an idiot and tried to use my previous DVD Drive to install on a new system, just for my luck I had a I/O error…

    I followed this guide and it was perfect… Windows installed in minutes!

    The only hiccup that I encountered was a failure in CMD to do a format, so I just used the Right Click > Format > NTFS and then did the CD Boot commands and it worked wonders

    Thank you, Sir.

    PS – Your face should be printed on money!

  1126. Bilal says

    “BOOTMGR is missing ” I m getting this message although everything else was successful as mentioned in the guide and then I copied the Win 7 all files into the USB flash .. but its not working and displaying the message i mentioned at the start .. plz guide

  1127. Amiel says

    Works great for windows 7! At first I was afraid of what’ll happen to my USB drive. After typing CLEAN, it displayed an error report and my USB device light kept blinking. I exited disk part and restarted the procedure. This time it worked perfect. I was able to reformat my HP laptop flawlessly. Thanks!

  1128. Ross says

    Has any one done a write up for doing this for XP?
    And if so what is the web address?
    OR what are the steps for doing this for a XP installation?

  1130. Tony says

    Didn’t work…. When I typed in LIST DISK it first showed only my hard drive… Then I put my flash Drive in another port (K) and when I typed in LIST DISK it gave me a list of dos commands…. Do you know why?
    Thanks

  1131. Charlie says

    This works everytime :) Been using this every now and then and it works allways! Really great tutorial. Works just as well with Windows Server 2008 R2.
    Thanks for a great tutorial.

  1132. Kevin Harms says

    Great docs, easy to understand. What I found is I had to do the bootsect /NT60 h: after the file copy, then it seemed to work.

  1134. nishiki says

    This has got to be the best how-to for usb boot I’ve come across. Thank you very much for it.

  1135. Souvik Dey says

    Hi,

    Since i have my Win 7 files as an iso file, i have extracted the image onto d drive. Can i use the steps you mentioned and instaed of “D: CD BOOT”, i can use the drive i have the files in and proceed as you mentined but just changing the drive letters accordingly.????

  1136. silky systems says

    there are a bunch of idiots in all these post this method works fine and even works to creat a xp install from usb but for all the dummies who dont read the directions right just leave your computer the way it is yes you need x86 to create 32 bit boot disk as you need x64 version to creat x64 also less you doo all this from a virtual machine you can bypass all the steps after diskpart and use the simple “xcopy d:\*.* /s/e/f e:\” with the actual disk or mounted iso image or for even the short buss cumputer techs on here just download win to flash if you dont know how to code or understand the simple comands given to you

    thanks for your great work TWEAKWINDOWS

  1137. Unknown Singer says

    read your post..followed the steps. really worked for me .. thanks a bunch.

  1139. didii says

    @Themba & hamza: Be sure to run the cdm (or command prompt) as administrator. Step 2.

    Thanx for the method :) But be sure not to do the ‘clean’ action on just a partition of your drive. Clean works for the whole disk (even if you selected just a volume/partition). Just lost 350Gb of files because of that -_-

    But thanx anyway :D

  1140. fieznur says

    COOL!!! This is the most easy & most detail instructions ever! Thanks a million!

    Plz help..thx

  1144. Lee says

    I was able to do all the steps on a 4 gb flash drive, but i ran out of space so I purchased an 8 gb. When I get to step 4 – creating the partition I get the following error: there is insufficient free space to create a partition at the specified size and off set. Specify different size and offset values or don’t specify either to create the maximum size partition.

    I have tried several times with same error. As I noted above the first time on the smaller flash drive it worked fine. Any idea?

  1145. Nicholas Corona says

    @EVERYONE WHO HAS HAD THE “BOOT MGR MISSING ERROR”

    SOMEONE ELSE HAS ALREADY MENTIONED THIS, BUT IT WAS RIGHT SMACK IN THE MIDDLE AND UNNOTICEABLE. IF YOU ARE HAVING THIS ERROR CHANCES ARE THAT ON YOUR USB FLASHDRIVE OR HARDDRIVE THE NECESSARY FILES ARE SAVED IN A FOLDER PROBABLY CALLED “CD-ROM”. YOU MUST EXTRACT THE FILES FROM THAT FOLDER AND MAKE SURE THEY ARE AT THE ROOT OF YOUR FLASHDRIVE/HARDDRIVE INSTEAD OF BEING TRAPPED IN SOME ADDITIONAL FOLDER.

    HOPE THIS HELPS!!

  1146. hamza says

    hi,

    @phil and @Hero,

    Make sure you’re aopening the command prompt with admin rights.

    Start menu -> cmd -> right click “Run as admin”

    I’ve used this guide 4 or 5 times in the last week. Lots of users here seem to be getting cd/dvd drive-less laptops.

    Even the walkthrough on MS’s website doesn’t have step 7. Great walkthrough for booting to a Windows 7 installation from USB.

    Thanks very much.

  1172. K.K.Vinay Kumar says

    What if the USB drive is already formatted in NTFS file system? Is it ok to skip the “FORMAT FS=NTFS” step?
    Reply me as soon as possible.

  1173. Shankaranand says

    Hi Team,

    I have a problem with my DVD writer. Hence, I could not be able to do the Step – 5. Please advice.

  1177. phil says

    sir when i type the command “BOOTSECT.EXE/NT60 H:” IT SAYS that”could not map drive H:to an associated volume device ” what should i do man?

  1178. Hero says

    mine says
    couldnot map drive partitions to the associated volume device object:

    PLEASE HELP!!

  1179. Jrei says

    Question:

    If my optical drive is not working (that’s why I need this tutorial to reinstall/reformat my PC using Bootable USB) and I have my ISO image (also the extracted file) of Windows Vista on my hard disk, how about step 6? am I still using the CD BOOT command on this matter?
    Help, thanks!

  1181. Prerit says

    Can i know how to restore my usb drives lost space?
    Actually when I was trying the upper steps..my usb is showing 125Mb memory while it was of 16GB….Please help somebody….

  1182. Addelini says

    Hey there, I don’t know if this question has been answered before but, can i use this on my external harddrive ? And can i use this without having the installation files? since i dont have a Installation DVD is the installation files somewhere on the current harddrive?

  1183. ATUL says

    I completed the task upto 4th step completely..
    as i m not having the optical drive, is there any other way because i am having the setup files of windows7 in my harddisk.

  1184. Moe Ali says

    Hello,

    I just wanted to thank you for this step-by-step guide.

    It was amazing and it worked PERFECTLY fine.

    Thank you again.

  1186. Vig says

    This guide is much better than any other I’ve come across, esp for how to format the usb drive. Thanks!

  1187. sibin says

    Thank you very much , ……
    I was looking for this from a log time , i tried and is success.
    Thnks once again …..

  1188. Jeff says

    Thanks for he helpful tip. I just got a new CPU/MOBO and turns out it doesn’t have any IDE interfaces, and I have no SATA DVD drive! I used to image XP machines from a USB drive using GHOST and an HP/Thin Client utility… I figured there had to be a way to do this in Windows.

  1191. CK says

    Thanks for this guide, it saved me having to replace an external DVD rom, for all those that got the problem of “read error” all you need to do is substitute fs=ntfs to fs=fat32, that fixed my problem.

  1192. John C says

    For those getting the error of “There is insufficient free space to create a partition” …

    I was getting the same error. I had to CLEAN again and then it worked. You might also have to clean all.

    Hope that helps.

  1193. Bob says

    Additional to post 909;

    On a separate PC, boot from Win7 CD – try to install Win7 to the external USB disk – and get the same message as above.

    Not sure why it’s not working for me.

  1194. Bob says

    Hi,

    Great doc – thanks.

    I’ve done this now 4 times – but I get stuck at the end.

    The whole process works as described, and I *can* boot from the external USB disk.

    Interestingly, the bios quickly flashes that there is no boot device – but then it does boot from the external USB disk and runs the Win7 installer.

    However…when I try to install Win7 (clean install) – and I list the 2 partitions (1st one is the main C: Drive and the second listed in the USB partition [Disk 1 Partition 1]) I get the message:

    “Windows cannot be installed to this disk. Setup does not support configuration of or installation to disks connected through a USB or IEEE 1394 port.”

    Any hints?

    The bios does allow booting to USB – and as above, the laptop does boot OK into Win7 installer – I just can’t install it?

    Thanks.

  1195. Max says

    Just wanted to say “thank you”, I’ve been using this guide for a while and it always works and always helps! Thank you

  1199. Mike Vango says

    Works Perfect with Windows 7. Followed the guide and worked like a dream..!
    Thanks for a super duper guide.!!

  1202. Shang says

    Oh My God, I cant do anything when the error display the message in the empty box:
    ”
    Install WIndows
    No dirves were found. Click Load Driver to provide a mass storage dirver for installation”
    ”
    Notice: I did step – by – step as 9 steps above,all ok. But when I install windows 7 (set BIOS priority to USB ok), the error displayed.
    I hope you help me.

  1204. SupaTom says

    For some of you who cannot get the USB to recognize or the USB to boot, chances are your USB flash drive itself doesn’t like to be a boot device.

    My 4GB Cruzer Micro refuses to be a boot device, while my 4GB OCZ ATV has no problem. Keep this in mind.

  1206. Karaciite says

    hey,
    can the USB be used again as it was before copying windows 7 setup in it? or its turned into permenently a Windows 7 setup drive ?

  1207. samraat says

    Can we format our pen drive or sd card after installation??
    Can that be used as a normal pendrive after installation??

  1210. Gi joe says

    Diskpart is different on XP to Vista and Windows 7. So the above guide probably won’t work in XP because some features of Diskpart that work in Vista and Windows 7 don’t work in XP. We found this out at work over a year ago when attempting to do the same thing.

  1213. SuperTareFrate says

    Works 100%, tested and running windows 7 installed from USB Stick! Nice work!

  1214. sam says

    hey guys wy wasing time on windows try linux mint one dvd will install all of ur needs. vlc open office image editor all drivers and u can boot live using a pen drive no need to install it!!!

  1216. Al says

  1217. Rooli says

    Thank you for your post, it helped a lot,
    every step was correct, and it is faster,
    than using DVD.

  1224. Willi says

    Hi, I followed the guideline upto step 7. I used a 4GB usb stick but the Windows 7 DVD contents are 4,78 GB large. How is it supposed to fit into the stick. Thanks

  1225. tarun Purohit says

    i am create a bootable for 2 gb pen drive for xp.

  1227. Aaron says

    @feyaz no if it said its not formatted then all the data on it is already gone.

    On another note, this worked great thanks.

  1228. feyaz says

    hey, I screwed another hard disk with these codes, it’s obvious that I made a mistake. I had more than 600gb data in it. Now when I double click on it in my computer it says it’s not been formatted.
    Is there a way I can recover my files?

  1229. Chaz says

    To all those receiving ‘disk read error’

    I had this problem and strangely evaded it by simply having a second USB stick in the computer at boot up.

    It was a Ubuntu USB boot that I had made but strangely somehow it managed to prompt the Windows 7 Install USB to boot.

    Makes no sense at all but it worked!

    Good luck

  1230. ali_J says

    hey i am also getting the error “a disk read error occured Press Ctrl+Alt+Del to restart” after trying to boot from the usb

    i see there are several people who has this issue but is not resolved. admin if there is no solution, can u please provid an expaination :D

  1231. admin says

    @Jogh

    If you don’t have a working optical drive and have an ISO file of Windows 7, simply mount it using Virtual Clone Drive.

  1234. Smo says

    Thanks so much for the effort here, really comprehensive guide, saved me alot of hair pulling. A very important webpage! Keep it up! :)

  1235. aaron says

    guys, you gotta remember to move the files on the root of the USB drive. IF THEY are in a CD_ROM folder, Bootmngr will not be found by the BIOS

    good luck and thanks for the awesomeness

  1236. riz says

    what if my windows 7 dvd is not a bootable 1??will it work ??like will it copy all the files on the usb and work as a bootable 1?

  1237. Mazahyr says

    Hi i’m able to do all the steps right but i can’t make it sure whether it is bootable or not. When i attempted all the mentioned step the windows “icon” appeared on the USB drive. Now when i open it by double clicking instead of opening the autorun setup window, it explores the USB. Wat indication will help me know whether it has become bootable or not. Plz urgent help required.

    hi gys i found that problem……
    Hlp is here XD ….late but Got it :P
    4. Next type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.

    So below are the commands you need to type and execute one by one:

    SELECT DISK 1

    CLEAN

    CREATE PARTITION PRIMARY

    SELECT PARTITION 1

    ACTIVE

    FORMAT FS=NTFS QUICK

    (Format process may take few min)

    EXIT…

    u will be back to c:
    then again type…your drive name “D:” (DVD Drive name)
    AND SAME AS GIVEN THERE
    D: CD BOOT
    D:BOOT>BOOTSECT.EXE /NT60 H:

    Relly u did it Finaly

    MY QUESTION IS WHAT IS FIRST THING TO DO BEFORE I COPY WIN7 INSTALLER INTO THE USB..BTW I GET THE INSTALLER IN TORRENT WITH THE .UIF EXTENSION.

  1248. DaGoof23 says

    Not sue if this has been mentioned before, if so, please delete my post.

    First of many thanks for this great guide!

    Created a Bootable pen drive with it and pluged it in only to get the message: “BootMGR file is missig”

    Solution in my case:
    Removable device Boot in Bios was enabled, but the Bios maped the Pen as a harddrive, so even if i manually chose: “Boot from removable device” BIOS didn’t find any and jumped to boot from Harddisk where it found no BootMGR.

    When inspecting bootsequence in BIOS i could expand the entry “Harddrive” the expanded entry showed the built in harddrive as first device and the pen as second.
    Well i switched the pen to first device and it worked.

    Sry for this long explanation, i hope it can help.

  1249. jadajada says

    WOW big ups to you sir, i can confirm it does work on older systems. Provided the system has the option to boot from a USB device,it will work. everything went great! thanks you very much.

    p.s this was my first attempt at booting from a USB device and you made it very clear and straight forward.

    i can’t thank you enough. keep up the great work. K + + +

  1250. jadajada says

    does this process work on older systems which do offer booting from USB devices for instance a dell dimension 2400 please post when you get a moment.

  1251. lovejeet singh says

    Kairoko,

    Hi – all you have to do is plug it into any machine and right click on the drive and format to either FAT32 or NTFS :) and then VOILA!

  1256. Kairoko says

    Is there a way to get the USB to work for other purposes again afterward? Please reply to me asap, and preferably by email, if you can see it.

  1264. Major says

    I have made an usb also with this methos, i have always the same problem. at the first it does not ask me to press any key to boot which it begins automatically. So it never finishes the installation since when the system reboots after the first phase, the installation starts again loading the files. any suggest please?
    From a DVD there is no problem since it asks me to press any key to boot…

  1265. Nigel says

    If I make the key on an ASUS windows 7 will it work to repair a totally f-ed up medion vista who always gets a blue screen while booting in evey single mode?

    Thanks much, had a problem with access denied but read thread and I was not running CMD as administrator. Went back and ran CMD as admin and worked great!, needed win 7 for a NETBOOK format and reload.
    thank you for this guide!.

  1269. karthik0000 says

    Installing operating system through usb flash drive is really a difficult task how ever installing vista and windows 7 are now made easy using the usb flash drive. The above listed post explains a step wise approach to installation using sub flash drive. impressive post , keep updating more important stuff.

  1272. 11225e says

    Hi. I’ve read all the posts hoping to solve my issue – but no luck. I hope someone has the answer…
    I am trying to make my 1TB eGo USB 2.0 Desktop Hard Drive bootable. I am running Win 7. The bios hardware supports booting from a USB drive, and I am able to select the USB drive from the boot menu. But when I choose the USB drive, I get:
    A disk read error occurred
    Press Ctrl+Alt+Del to restart
    I am able to read/write from the USB drive normally via Win 7 with no problems. The USB drive is formatted NTFS and could this matter – my computer is 64 bit and the USB drive is formatted with whatever you get when you select NTFS – would that be 64 bit in my case?
    Lastly, when I try the Windows 7 USB Tool, I can’t even get past selecting an ISO file – it says mine are invalid.
    Is there any help for me??

  1273. Hey Bek says

    Hey Bek. Normally the DISK # would be the last on the list. Before you start, unplug any other external device from your system. And note if you have more than one internal hard drive. So if you have 2 internal drives and the one usb drive (the one you want to load the boot on), then the list would be:

    Disk 0 (1st internal)
    Disk 1 (2nd intermal)
    Disk 2 (external)

    Also the Size column, in your case should be a little under 4 gig. Will show something like 3242 MB.

    Hope that helps :-)

    This is a perfect guide that does exactly what it says. Anyone who has problems with this guide is a noob.

  1285. aRjay T. says

    Hi! I have been using this Howto coz its really working. One observation though, after I converted the usb as a bootable win7 installer, I couldnt use it as file storage anymore. This happend to a brand new usb as well as my good old usb that has write protect switch.

    Everytime I try to store files on an already bootable usb, its as if the the system releases the usb (like as if I ejected it) then after a few seconds, the system detects it again that its there and will offer for a scan for error. If I choose to scan, it wont push through and re-offers it again and again.

    Btw, I cant format nor do anything to the usb’s partition.

  1286. Ryan says

    Everything went smoothly and I could boot from the USB but after that there is a message thy says: Bootmgr missing press ctl alt del to restart how to fix?

    i tried the steps suggested to format laptop using usb after insert the usb(pen drive 4gp) in usb port. in second step i typed LIST DISK . it list out disk0 only. it did not list any other disks such as disk1 for usb that i was inserted. so i cant proceed further .please tell me that how can i proceed further.

    Great stuff. Worked like a charm. I tried another method that didn’t boot at all, but this one worked on the 1st try. I dir get an ACCESS DENIED when it tried to lock the disk for the ‘bootsect.exe /NT60 h:’ command, but it worked anyway. If you do it this way you’ll end up where you wanna be. Thanks!

    Please suggest ….. :(

  1295. HakuginLabs says

    @Alex
    Sorry, forgot to add this to my previous comment.
    There are a few options for restoring the memory card to being usable in your phone.

    Option 1: Delete the partition and create a new fat32 partition (I’ve noticed a lot of phones don’t recognize ntfs easily, some do). This is the easiest option

    Option 2: This is for advanced pc users.. You can download and burn off a “Live” version of linux that will boot from disc and provide a full linux environment and use a disk partitioning program like gparted or Disk Utility

    I recommend option 1, worked for a co-worker that had run into the same issue.

  1296. HakuginLabs says

    For those having issues with not having a dvd to copy the files from. Use a virtual drive, there are a few good free programs that will mount iso images into a virtual dvd drive.
    For people having issues with the bootsect.exe step, you will need to make sure you are using a 64bit OS to create a 64bit usb installer. I ran into this myself using 32bit vista on one of my laptops. I had to use my 64bit vista laptop to create a 64bit windows 7 usb isntaller for my netbook.

    And remember to run Command Prompt as admin, if you run into issues with cmd prompt dropping admin privileges after exiting diskpart, you may be having an issue with the UAC. Just open a new cmd prompt as admin (easiest fix).

    Great guide btw. Allowed me to format and reinstall 7 (using the DVD provided by the manufacturer) on a netbook without using an external dvd drive which I did not have the money to buy.

  1300. Alex says

    Hi,
    thanks for the support it worked perfectly!!! :)

    I tried to install the way this tutorial said but at the formating the memory stick as NTFS it taked me samething more than 1 hour and got an error of formating also. So I had formated as NTFS in Windows 7 and copyed the files from the win7 image mounted with daemon tools (drag & drop – I had unchecked “Hide protected operating system files” from Folder and search options)and worked just fine with installing windows 7 on another computer.

    CREATE PARTITION PRIMARY
    SELECT PARTITION 1
    ACTIVE
    FORMAT FS=NTFS

    Hi Al

    I had the same – look at #577 and change to “never notify”
    BUT I had to reboot – after I changed to “never notify” – before it worked.
    After reboot – you can go step 6 – by open the cmd again.

  1336. Andreas says

    Works just as described. Thanks very much, saved my bacon after realizing Mom-in-Law’s PC didn’t have DVD drive.
    To Al: had same error. Make sure you are running CMD as Admin. If it doesn’t prompt you for permission on launch, you didn’t launch it right. Use the right-click “run as administrator” option.

    Hi. i have followed you guide and i got to boot the usb successfully, but when windows 7 starts. it doesn’t get to the installation process, it’s just stock on the windows 7 background and the mouse pointer, what do you think is the problem? is my motherboard not compatible ? i have asus p5sd2-vm. or is it with my installer that has the problem?

    thanks in advance! :)

    Hey i am trying to follow your steps… But when i write BOOTSECT.EXE /NT60 F:(MY USB DRIVE LETTER IS F) THEN I GOT THIS MSG

    “TARGET VOLUMES WILL BE UPDATED WITH BOOTMGR COMPATIBLE BOOTCODE.

  1353. bmac3 says

    Guys please help me. CMD crashed when I was doing the FORMAT FS=NTFS at 23%. Now my USB-Stick isn’t working because it is displayed as NTFS. I can’t access it at all. How can I get it right again?

  1354. Manjunath says

    Helped me very much to install windows 7 using usb. Just ensure that you run Command Prompt as Run As Adminstrator (Right Click Option on cmd). I wasted much time using normal mode.
