How to fix "Unable to run bootsect to make the USB device bootable" Windows 8.1


When i try to create a bootable USB device using the Windows 7 USB DVD Download Tool, i am seeing the status “Files copied successfully. However, we were unable to run bootsect to make the USB device bootable.”
Solution: This may happen if your’e trying to create a 64 bit bootable usb device from a 32 bit version of windows. Because, bootsect.exe file is missing in the Windows 7 USB DVD Download Tool installed directory. So, download “bootsect.exe” and save it to the location, where you have installed Windows 7 DVD USB Download Tool.

  1. Whilst I appreciate your trying to help people you REALLY need to sort the layout of your videos with all these adverts and other notifications on the screen you have saturated the video so much so that its hard to see what it is your trying to explain…

    Download this
    open that download folder in cmd admin
    Type or copy-paste following
    bootsect /nt60 E: /force /mbr
    Replace E: with usb drive
    Done! Now good to go

  3. Also, if you have UEFI BIOS even if you try to make a 64bit bootable drive on a 64bit install and even if you have bootsect and even if you try running it from command line you may get following error:
    "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."
    If you have such problem just download some other tool for creating a bootable drive (e.g. Rufus).

  4. It is a great suggestion but I am trying to do it in Windows XP , I couldn't find the installation directory in windows XP. anything u could help..???

  5. bootsect must be download and put in folder.

  6. It worked for me, but I had to copy the bootsect.exe from the Windows10Update folder. Both the exe and the Win 7 were x64.

  7. Had the same problem. Did not work after copying the file manual into the folder or by running the bootsect command.
    Just skip this program. Even this little snippet of code M$ can't make right. Download It takes less than half the time to get the iso to disk and bootable. It just works.

  8. This did the trick!:

  9. Nope. Didn't work. For all I know I copied the bootsect file into the wrong directory… there were no instructions here on how to find the correct directory.
