    Bootsect.exe on x64


    Hi, I have the bootsect.exe problem where I can't create a Windows 8 bootable flash drive because it says windows cannot run bootsect.exe. This problem is supposed to happen when you're writing x64 windows 8 with an x86 machine. I am using an x64 machine and having this problem. I'm using the windows 7 to usb tool from microsoft. I've also tried that josh cell softwares application and it doesn't work either.

    One of those tools will not run from a UEFI install. Maybe it is Bootsect.exe, I can't remember.

    bootsect gets installed when you install the ADK - given the package is x86 or x64, it shouldn't matter which you download as it should install the correct version properly. And a UEFI system can still install an nt60 bootloader on a USB key, as I've done it a few times now, so the error shouldn't have anything to do with that.

    Best bet is to do the following from diskpart after redownloading and uninstalling/reinstalling the ADK:
    sel disk # (replace # with USB key disk number)
    clean
    create par pri
    sel par 1
    format fs=fat32 quick
    active

    Then open the deployment tools cmd prompt (not a normal cmd, but the specific one ADK creates when you install the deployment tools that way) as administrator/elevated, and run the bootsect command against the USB drive letter with the /nt60 option. If it still fails after that, let us know.
