A couple of years ago, during the days of Windows XP and Vista to be precise, we all used to use traditional CDs and DVDs to install Windows operating system. Post the release of Windows 7 Beta in January 2009, a number of tools started appearing on the web to create bootable USBs that help you install Windows 7 from a USB drive.
Microsoft also released an official tool, a few weeks before the release of Windows 7 RTM to the public, called Windows 7 USB/DVD Download Tool to help end users create bootable Windows 7 USBs from ISO image files. Tools like Rufus and WinUSB Maker are capable of creating bootable USB compatible with both tradition BIOS and new UEFI systems.
But there might be situations where you have Windows 10/8.1/7 ISO file but don’t have a USB drive to prepare and install/re-install Windows from a USB drive. Thankfully, Windows 7, Windows 8/8,1, and Windows 10 can be installed from your phone’s memory card as well.
These days, almost all of us own at least one smart phone and most of these smart phones, barring iPhone, support Micro SD memory cards. So finding a memory card isn’t a hard task, and since all of us carry our phones everywhere, we can quickly move the SD card data to a PC, prepare the bootable memory card, and then install Windows from the memory card.
In this guide, we will show you how to create bootable Micro SD memory card and use it as the bootable media to install Windows 10/8.1/7 from the same. Follow the given below instructions to prepare your Windows 10/8.1/7 bootable Micro SD card and then install Windows 10/8.1/7.
Preparing Windows 10/7/8.1 bootable memory card is fairly a simple job and you need to follow the same procedure that you followed to create Windows 8.1 bootable USB drives.
NOTE 1: Memory cards, other than Micro SD, can also be used to prepare bootable media and then install Windows from it.
NOTE 2: Before using the Command Prompt to prepare the bootable media, I tried the popular Rufus tool to make memory card bootable but it failed. Other similar tools out there might help you in preparing the bootable memory card but we’re going to use the 100% working instructions provided in our how to install Windows 10 from USB guide to prepare Windows 8.1/10 bootable memory card.
Making your Micro SD memory card bootable
Procedure:
Step 1: Remove the Micro SD memory card from your phone and attach it to your PC either using built-in or an external memory card reader.
Step 2: Back up all data from your memory card to a safe location, as we’re going to format the memory card which will erase all data from the card.
Step 3: Open elevated Command Prompt. To open the Command Prompt with administrator rights, type CMD in the Start screen or Start menu, and then simultaneously press Ctrl + Shift + Enter keys. You can also refer to our how to open Command Prompt as administrator for detailed instructions.
Step 4: In the elevated Command Prompt, execute the following commands:
Diskpart
Press Enter key.
List Disk
Press Enter key.
Notice the disk number of your memory card. For example, in the above picture, my memory card’s disk number is 1.
Step 5: Next, type the following commands one after another and press Enter key after tying each command.
Select Disk 1
In the above command, replace “1” with your memory card’s disk number that you have obtained in Step 4.
Clean
Create Partition Primary
Select Partition 1
Active
Format Fs=NTFS Quick
Assign
Exit
Don’t close the Command Prompt yet.
Step 6: Next, mount your Windows 10/8.1/7 ISO file to get a drive letter for the mounted drive. If you’re on Windows 8/8.1, right-click on the ISO file and then click Mount. And if you’re on Windows 7, please go through our how to mount an ISO file in Windows 7 guide for detailed instructions.
Step 7: Execute the following three commands:
G: Cd Boot
Where “G” is drive letter of the mounted ISO file
Bootsect.exe /NT60 F:
In the above command, replace “F” with the drive letter of your Micro SD memory card. That’s it! You can now close the Command Prompt.
Step 8: Finally, copy all files (including hidden, if any) from the virtual drive (ISO file mounted drive) to your memory card. Your bootable Windows memory card is now ready.
Step 9: Turn on the PC on which you would like to install Windows from the bootable memory card, connect the bootable memory card, boot into BIOS or UEFI, re-arrange the boot order to bootable from memory card/USB and restart the PC to see Press any key to boot from CD/DVD message on the screen.
Press any key to begin loading necessary files and installing Windows 10/8.1/7 operating system. Good luck!
NOTE: Should your PC doesn’t show memory card in the BIOS/UEFI and doesn’t support booting from a memory card, you can put back the memory card (after preparing the bootable one) into your phone, connect the phone to your PC using a supported cable and then restart your PC to boot and install Windows. It worked on our PC, at least.

Stevetotheh says
Utterly useless. If you need a computer then what is the point of using your Android device at all?
Jameson says
WinSetupFromUSB-1-7.exe from Igor Pavlov. Make a TF card 64gb to include win10, win7, and DLC Boot ( contains live10x86 live10x64 acronis 2016 etc ). Put also various programs needed after installation of WIN. Put the 64GB in NOKIA 215 ( was formated fat32 ). Carry the USB to microusb cable, plus the Nokia phone. Can install windows or boot to DLC.
Devin says
This line from the USB instruction page is missing from this version of the instructions, and may not be obvious to all users:
FORMAT FS=NTFS QUICK
IMP: If your PC supports UEFI, please format the drive with FORMAT FS=FAT32 Quick command.
Nigerian says
we r very glad with your guide bross, keep it up, your tweak works perfectly.
Kita says
Does the SD card have to be 32?
AS says
Oke guys, I had same problem to when use bootsect.exe
Target volume will be updated with BOOTMGR compatible bootcode
“could not map drive partitions to the associated volume device objects
access is denied
and I know how to fix it, all you should to do is, run cmd with “Run as administrator” then repeate the proses
*You can locate cmd.exe in C:/Windows/System32/
and then its works :)
MIKE says
this is the error i got bro
Target volume will be updated with BOOTMGR compatible bootcode
“could not map drive partitions to the associated volume device objects
access is denied
Swapnil says

@ Vakhtang
Glad to know that the guide helped you.
vakhtang says
thanks a lot for great guide! it worked perfectly! a repaired my pc from my phones sd card!
Gaurang says
Well Awesome Its Worked
But prob with copying File last step
Steve says
For those of you having a difficult time getting the Bootsect.exe step to work, it works granted the actual .exe file isn’t in a folder. In my case, upon opening the .ISO image, the Bootsect.exe was in the ‘boot’ folder.
So to fix it make the command as such.
D:\>/boot/bootsect.exe /NT60 E:
boot may not be the name of the folder within your .ISO image, but the idea is to direct it to the name of the folder that contains the bootsect.exe file.
Good Luck!
ARYAN MISHRA says
HEY,,,(Bootsect.exe ) IS NOT WORKING CAN ANYONE HELP ME AND EXPLAIN IT IN SIMPLE WORDS HOW TO USE IT I TYPED IT CORRECTLY
stee says
Sounds great. Problem is, that my Android 4.3 phone does not support NTFS…
Sladjan says
Is there a way to make bootable memory card directly in a phone?!, I dont have card reader
Stephen says
GA, make sure you are in the Boot directory of the mounted drive when running it.
Lewanna says
You are so awesome. Thank you a million times over. You just saved my ass so completely.
Ga says
Bootsect.exe command is not working on my pc i typed it correctly
Julia says
Thanks for the tips. it saved my time & money also.
Robert says
Just an FYI. This won’t work for UEFI if you have to format as NTFS. UEFI will only “boot” from a Fat32 partition. It’s why UEFI installs of Windows have an extra Fat32 partition setup when installed in that mode.
