    Also do I need to delete bootmgfw.efi out of the install.wim folder after it's renamed and copied to EFI/Boot? How?
    When making a Windows 7 install flash drive, the only change to the Windows 7 directory structure, as copied from an Install DVD/.iso if mounted, is to add the Boot folder to the EFI folder and then throw in the bootx64.efi.

    EFI\Boot\bootx64.efi

    If you were to look at a Windows 8 DVD, it will have the correct directory structure so nothing has to be added to it.

    Everything else remains the same. The EFI\Microsoft\boot folder with all the files, stays where it is.

    I suppose it should be mentioned that the OEMs are setting up their systems as they so choose, so there is a possibility of something related to that causing problems with dual booting Windows 7. It just does not look as though that is involved with your results.

    As long as you have a flash drive with a Fat32 partition set to active and the Windows 7 files copied to it with the above modification, you should be fine.

    I wasted a half day with unbootable stick due to this step apparently being incorrect in tutorial:

    11. If Using 64-bit Windows 7
    NOTE: Thank you to theog for this step. You do not need to do this step unless you are creating a 64-bit Windows 7 UEFI USB. If not, then go to step 12 below instead.

    A) On the USB flash drive, copy the efi\microsoft\boot folder up one level into the efi folder as efi\boot. (see screenshot below)

    Thanks to Saltgrass and SIW2 I undid step 11.A and skipped directly to step B,which resolved the problem.

    Perhaps the tutorial could be edited of Step 11.A which apparently isn't needed.

    Hello Greg,

    It's a correct and needed step for 64-bit Windows 7.

    It looks like you "Moved" instead of "Copying" it though. That would cause an issue to move it.

    Thanks, Shawn -

    To get it to boot I had moved the EFI\Microsoft\Boot with all the files in it back to where it was, then created a new Boot folder in the EFI folder to copy the renamed install.wim file bootmgfw.efi into, making it EFI\Boot\bootx64.efi. So what ended up working is:

    Hi Greg

    Just made four USB drives.

    May be worth having two Boot Folders.

    What folder are you adding the to?

    As you can see the EFI\boot folder in my screenshot only holds bootx64.efi. I had to move the Microsoft\boot folder back to Microsoft folder to get it to boot to UEFI.

    This is per Saltgrass's suggestion here: UEFI Bootable USB Flash Drive - Create in Windows

    @Greg:

    Looks good Greg. That's how the tutorial has it to be setup.

    Yep, moving that folder instead of copying was what did you in, but you're good to go now.

    I must have misunderstood because I copied the EFI\Microsoft\Boot folder up to the EFI folder (up one?) then moved bootx64.efi into it. Then it gets a black screen failure to read EFI file error.

    So Saltgrass told me to not move EFI\Microsoft\Boot folder up one but instead make a new EFI\Boot folder to copy bootx64.efi into, which worked.

    It's kinda got me dizzy so maybe someone can sort it for me.

    Greg

    Making a new folder in EFI & naming BOOT works fine.


    If you are making the USB drive on a Windows 7 x64 install, you can also find the bootmgfw.efi at C:\windows\boot\EFI\

    Yeah, creating a new "Boot" folder in efi\Microsoft would also work instead of copying the EFI\Microsoft\Boot folder up one level.

    Yep, you want to "copy" the EFI\Microsoft\Boot folder up one level instead of moving it at step 11A.

    I just found it easier to copy it, but either way will work.


    I have cleaned up step 11 to help make it easier to use. Please let me know what you think.
