    You need 2 partitions. I don't think a 16 GB flash drive will be large enough. Microsoft says minimum disk size for Windows 10 is 32 GB. The commands would be:

    Code:
    diskpart
    list disk
    select disk # <- replace # with the actual disk number for the flash drive
    clean <- this will erase the disk selected above!
    convert mbr <- probably not required but won't hurt anyway
    create partition primary size=100
    format fs=fat32 quick
    active
    assign letter=s
    create partition primary
    assign letter=t
    exit
    Then you will use the appropriate DISM command to apply the desired image from install.wim or install.esd in the sources folder of the Windows 10 ISO file (or USB flash drive) to the T: drive that you just created. After the image is applied the bcdboot command would be:

    Code:
    bcdboot T:\Windows /s S: /f ALL

    Gracias, will get a couple 32 or 64GB flash drive. Thanks.

    Edit: Hah, just found a 32GB buried in the pile. Onward!

    Do I need to convert esd to wim before running dism /apply-image? I want to use

    Win10_2004_19041.264_Multi_x64.iso

    which has install.esd, not install.wim.

    You can use install.esd

    7% of Apply-Image. Going to take awhile and I suspect booting it will be very slow. Interesting though.

    Edit: Took about 20 minutes to write the flash drive.

    Now it doesn't boot. Disabled Secure Boot, tried with and without CSM enabled. Flash drive shows up but doesn't boot.

    Edit#2 Crap, I forgot to do the bcdboot. Will do it now and that should fix it.

    Looking much better:

    Still won't boot. I'll see if I can take a picture of the Security and Boot windows in UEFI Setup.

    This is what the boot menu looks like.

    Under USB Key: SanDis, just tried UEFI: SanDisk and it didn't boot. I'll try Legacy: SanDisk next.

    Flash drives take forever to boot. Are you sure you waited long enough? I'm going to try a 32 gb flash drive now....

    Yes, it booted into my regular Windows 10 Pro after a few seconds.
