Last Updated on by 112 Comments

Computer users who have ever installed a version of Windows operating system from a USB flash drive will never go back to the traditional DVD installation method. As you probably know, installing Windows from the USB is the fastest method available to install Windows operating system.

Creating a bootable USB media to install Windows 7 from USB drive is fairly simple if you follow the step-by-step instructions provided in our how to install Windows 7 from USB guide. Users who aren’t comfortable with the Command Prompt can take the help of a third-party tool. There are quite a few free tools out there to help you install Windows 7 from USB flash drive (see eight free tools to prepare bootable Windows USB).

Now the good is that, Microsoft has just released a free tool called Windows 7 USB/DVD Download Tool to help users create bootable Windows 7 USB flash drives and install Windows 7 from USB drive.

    Thank you! It worked for me but not at first. The guide doesn’t specifically tell us to type “BOOTSECT.EXE /NT60 J:” (without the quotes of course). In my case J: is the assigned letter of USB stick. The guide/tutorial should tell noobs like me to type that in, lol.

    For others that may benefit: I did not have full retail version of Win 7 x64 SP1 so No Microsoft tools would work. In fact they have already starting redirecting critical (Win 7 hot fixes & tools etc.) links to “buy Windows 10” page. So I used freeware WinCDEmu to rip an iso file from my Win 7 x64 SP1 OEM disc. Tried Microsoft’s Windows 7 USB DVD Download Tool but it would not accept the iso file since not full retail. So I copied the iso contents to a folder & loaded them into the trial version of NTLite. Slipstreamed hot fixes, USB 3.0 & nvme drivers. For this tutorial I used WinCDEmu to mount the iso image that NTLite created. Then followed this guide & works like a charm.

  2. DONIA7337 says

    but what if I have a preinstalled version of windows 7 and the iso file can not be located ANYWHERE !!

  4. techdumb says

    I have original win 7 preinstalled, and want to make a bootable/backup copy on usb or dvd but don’t know how…
    Don’t have win7 on usb/dvd or any other drive.

  5. Tom says

    A quick note, USB 3 ports will NOT work on windows 7 without a previous copy of windows installed / the drivers. They require host controllers, if you’re installing windows 8 via a usb 3 port it should work fine as they have native support. method worked flawlessly for me installing win 7 professional via a usb.

  6. Junior says

    I have Dell Inspiron Mini 1018. Dell sent me Windows 7 Starter on a usb drive to reinstall Windows after my pc crashed. Any instructions when Windows on usb and not disc?

  7. Smaug says

    For those of you still having issues with invalid ISO, this is what i did. Follow IJas intructions.

    1.) Open ISO with PowerISO- Full Version
    2.) Go to File, File Properties
    3.) By Default, UDF is checked. Verify, it must be checked
    4.) Press ok
    5.) Go to file and “Save As”. This will re-create the ISO with UDF enabled and should only take a min.
    6.) Load the re-created ISO With the Windows 7 USB Tool and that should work. It worked for me.
    Good Luck and thanks IJas for figuring it out.

    2nd note: For those of you having NTLDR errors, Try reformatting you USB to FAT32 format, not NTFS.

  9. donald says

    I have a question: this tool works on Windows XP too? I mean, if i don’t have installed Win 7, only a Win7 kit, it’s ok?
    thanks.

  11. justin says

    i’m tried as given above but if i select the iso file the following error will display “The selected file is not valid iso file. please select valid iso file and try again later”. when i check the file properties ti shows iso image file.

  12. Hmm says

    ANOTHER POORLY written untested set of instructions.

    Most of us have legitimate versions of Windows on CD. What about instructions on how to get the Windows 7 CD onto the USB to speed up the process??

    Based on the many many comments here, this does not work.
    Thanks for nothing!

  13. Lachit Kashyap says

    Hi, I do all steps but when going to install it, found this message “A disk read error has occurred Press Ctrl + Alt + Del to restart” please help.

  15. keffie says

    okej the first comment with the iso thing helps but only if you have the full version of iso power just download iso power and when it start up click register code and get one from serials.ws this helps

  16. mercy says

    The method posted by Ijas is still working! Thanks, Ijas!

  17. Andrew says

    Worked great through USB 2.0 port, when I tried using USB 3.0 port it could not find a driver to install.

  21. azribohari says

    I created the ISO from original Windows 7 DVD that i bought. im using a macbook, installed with Windows 7

  22. azribohari says

    i tried the CMD thingy, it says “DiskPArt has encountered an error: The remote procedure call failed. See the System Event Log for more information”. At first I thought its my USD, so i bought a new one. But the same thing happened. I tried using the Windows 7 USB/DVD tool. It says “We were unable to copy your files. PLease check your USB device and the selected ISO file and try again.” Help!!

    To all people who have the problem (Invalid ISO File)
    This is the solution:
    Open your iso file in poweriso(full version) or ultraiso
    Go to File–>File properties
    Check UDF
    Press ok
    Save as your file
    and enjoy

    Kiki – it states at the start of this thread…

    Note: You need a USB flash drive with a minimum of 4 GB of free space. And also please backup your data from USB first.

    If you don’t have AT LEAST a 4GB USB Drive this will NOT work for you.

    I suspect that the 3.7GB free is due to the USB mfg placing other SW on the USB stick – copy all that off to a safe place, and delete everything from your USB drive. I bet you will see 4GB free then – if not get a bigger USB stick to do this.

    I’m installing Windows 7 Pro x86 on an Acer Netbook that had a HDD crash/replace right now using this method. I’ve also used it in the past with Windows 7 Ultimate.

    Works like a charm and SO MUCH EASIER than going the manual method!

    Cheers!

  27. techfreak says

    For those who get the ISO error:
    Procedure:

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

    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.

    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 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.

    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

    (Format process may take few seconds)

    ASSIGN

    EXIT
    Now use the app ! It works ! :D

  28. Kickass says

  30. DogPaw says

    I was curious if you need to download a ISO separate or is that located somewhere as a standard for this program to find on my system with a valid copy of Windows and my FLASH MEMORY STICK JUMP DRIVE shows halfway between three to four gigabytes free space but is that enough for a Microsoft 7 boot disk? A few other questions I wanted to ask are whether a XP computer would be capable of managing the newer version and my BIOS only gives two Universal Serial Bus options. The first being a Hard Disk and the second a Floppy and I put both as priority but neither attempts load a copy of Linux I verified works on another machine. I believe a virus is the reason my old platform fails to operate but either way I eventually come to a UNMOUNTABLE VOLUME blue screen error. My data is unimportant because this has occurred on a old laptop that was only being used as a spare, for research, guests or whatever but, if possible, it would be nice to find a way to still access the internet with it and have core applications functioning to access important sites like Java – Script, video, audio, movies, music, etc. Please advise if you know of any solutions with BASIC, THOROUGH instructions without all the million and one thousand DIFFERENT terms or command codes unless you can take the time to explain each step for me, use recognizeable DEFAULT words, etc. THANKS.

  32. freds says

    For this procedure to work you must have like levels of operating system.

    I.E. You can’t create a 64bit install on a 32bit computer as the last step it does to invoke a utility in the \boot directory to make USB drive bootable. A 32bit system can’t execute the 64bit program.

  36. Glufse says

    SO yeah, how do i get back my USB stick to become a portable storage instead of a “Hard disk drive”? Very irritating

  40. gcarvajal says

    use power iso 4.8. full version. goto tools–>create bootable usb drive then Select image source file then the write method start thats all make sure that ur boot priority is the uss depend on the write method you selected.

  41. Patrick says

    Hey, my computer recently crashed and needs to have Windows completely reinstalled. Unfortunately, I can’t even boot it up to do any of this on it. So I’m trying to turn my iPod (as my USB Drive is only 1 gb) into a Bootable USB device using the Windows 7 USB/DVD Download Tool, but I get this error:

    “Boot Sector Manipulation Tool has stopped working.”

    How can I fix this?

  43. Chiklu Master says

    For all you guys saying to check the UDF thing … it is already checked for me and it still doesnt work !

  45. Debashis Das says

    wher is the iso file icould not find it any whwre even inthe windows 7 dvd….. microsoft and you all are all mother fucker put the usb in your mother,s pussy.

  47. Steve says

    Works perfect, once you find a working ISO file. Pre-select boot to USB in BIOS, or in Boot Options (HP Mini). Works great on netbooks even ones with small 16GB SSD HD’s. The transfer time from ISO to USB 2.0 took about 20-30 min. After that it’s normal vista/7 install!

  48. nibodads says

    yeah it works. but u need to make the iso valid with power iso as said above (check the UDF box in file properties)

  49. Navi says

    i have successfuly made bootable window 7 usb but when try to install it after expanding 20-30% it generate error. 0x080070570 file corruption like. also i haven’t dvd-rom so please give me solution…this only happen with window 7 not with window vista

  52. Tiiki says

    Very easy and helpful tool. Thank you very much!

    My step:
    1. Format 4GB USB Flash drive (HP USB DISK STORAGE FORMAT TOOL)
    2. MagicISO
    3. Windows 7 USB/DVD Tool (around 15-20 mins)
    That’s all :)
    Cheers!

  58. LoonyBinJim says

    after inputting the isoavdpcopy
    at the dos prompt, an error shows that says
    ERROR: Specified ISO is read-only

  60. Horia says

    I used gBurner to change the properties as recommended in a post above.

    I’ve unchecked all, leaving only UDF, and then Microsoft’s USB tool worked my iso file.

  62. Sai says

    I have tried this but failed to install Windows 7. The system is saying Installation has not done.This is the only message am getting. Please will any one help me on this

  65. Brian says

    Everything worked fine until the very end. In the copying files stage, it gets to 99% and then I get an error message that says “We were unable to copy your files. Please check your USB and the selected ISO file and try again.”

    Help?

  66. Daniel says

    do you think there is a problem to make these on XP?

    i’ve made the USB after using power iso
    but is not boot-able
    the parent iso file is booting

  67. gBurnerWorksTo says

    I used gBurner to change the properties as recommended in a post above.

    UDF was already checked, but so was Juliet and ISO-something-or-other. I unchecked them, leaving only UDF, and then Microsoft’s USB tool worked on the torrent recovery disk I had.

    Thanks for posting guys.

  68. Houston says

    Thank you! The first way works perfectly for me! And it installs super ridiculously fast. Very much appreciated. Also had fun doing it in DOS, not everyday these days that things are done in CMD Prompt.

  69. Amit says

    To use that Microsoft tool u have to use original Windows 7 ISO File otherwise, it will give this type of error… or use Power ISO trick….

  70. Win7easyinstall says

    To all those having problems,

    If your iso is classed as invalid check it with power iso using instructions from: IJas
    Open your iso file in poweriso(full version)
    Go to File–>File properties
    Check UDF
    Press ok
    Save your file
    Now use this tool!!

    Also if you still having problems use the long (but working) guide: intowindows.com/how-to-install-windows-7vista-from-usb-drive-detailed-100-working-guide/

    One last thing… if you are running a 32bit os on your computer you cannot make a 64bit install drive! I think its the same for 64bit os trying to make a 32bit drive aswell!

    Any more questions? Just Ask!

  71. james says

    i would download a iso of windows 7 cause the one on the disk is a exe not iso, or you could make a iso of the disk and do it like that, my friend used this to redo his acer notebook cause it doesnt have a dvd/cd drive in it

  72. oscar says

    Guys, where do I find the ISO file in windows 7 starter on a netbook? I never downloaded this version because it was already on my netbook. I simply want to reinstall it.

  73. Manish says

    Hi , have just created flash drive through win2flash..how to install windows now to my new mini laptop..cant go to bios settings..plssssssss help

  75. Naval says

    If I make usb as bootable, can I store other files or data in it with that iso file? or I will have to keep this ISO file forever there without using it for any kind of data store.

  77. RR says

    Didn’t work for me. got a iso from msdnaa but still the same problem. trying to install windows 7 on a asus netbook for almost 7 hours : D fucking shit

  78. abe says

    i followed all the instruction but failed to recognize that my netbook is xp running in 32bit. It says cpu can’t work with 64bit. is on earth a way to get my netbook installed with win7?

  80. manu says

    To all people who have the problem (Invalid ISO File)
    This is the solution:
    Open your iso file in poweriso(full version)
    Go to File–>File properties
    Check UDF

    Save your file
    Now use this tool!!

    This method work perfect for me with iso file downloaded from torrent sites

  82. Suren says

    You guys are retarded. I followed through the other guide for 3 hours, and then at the end I saw this. Instead, can’t you just friggin stick this at the top of the guide?

  84. Valentin says

    CMD:
    diskpart
    list disk
    select disk #
    clean
    create partition primary
    select partition 1
    active
    format quick fs=fat32
    assign
    exit

    after that everything worked perfect (also I had to stop the anti-virus as once started copying the files it deleted the auto run as a virus)

  86. Micky says

  90. Imperative says

    do exactly as IJas said in his post.
    u can use gburner also(unregistered version also works).
    u can find that option in properties menu. check the option and save the files in iso format. hope it works for you. worked for me.
    :)

  92. ROFL says

    ok… intowindows.com/how-to-install-windows-7vista-from-usb-drive-detailed-100-working-guide/ and simply do as it says!! THIS METHOD WILL NOT FAIL YOU. the program might not let u load up the ISO cuz maybe u didnt buy it or who knows.

  95. IJas says

    Open your iso file in poweriso(full version)

  98. STARTER says

    hey this works just with windows 7 starter i have downloaded all the versions of windows 7 and only the starter works i have tried all the ways to make an ISO to work with it but didn’t. SO make an usb bootable with windows 7 starter and then delete all the files from windows 7 starter inside the usb and put the files from windows 7 ultimate.

    have fun

  100. TechnoCrat says

    This tool was made open to people who bought the software from them as a ISO online. It seems to be doing some kinda check for size or something.

  104. Kalle says

    what shall i do when the “The selected file is not a vaild ISO file. Please select a vaild ISO file and try again.

  105. Darklord says

    Does Microsoft’s tool work with the RC versions of Windows 7?

    I am still undecided as to upgrade to windows 7.

  108. Niels says

    HI, i haven’t tryed that.. yet.

    I have one question.
    does it come up with windows 7 in the boot manager, so you can chose vista or win 7?

    Plese send repley to me email

  110. Koz says

    The same as Sten isn’t working

    The selected file is not a valid ISO file. Please select a valid ISO file and try again.

  111. Sten says

    Excellent utility from Microsoft. Thanks for posting this article so I didn’t have to do it by hand, like I did for the Betas.
