    Hello,

    I'm trying to install Windows 7 Ultimate x64 in UEFI mode but when attempting to run the USB at my PC, I see the following message

    Is there any way to fix it? This PC came with Windows 10.

    Thank you in advance

    What GPU do you have? Does your motherboard allow enabling CSM/Legacy mode?

    I updated posted picture, you can now easily track files, that you need to add :) Replace cs-CZ with your language and bootmgfw.efi = bootx64.efi

    And you need to use UefiSeven, then do these steps. On setup media and in install.wim too

    Code:
    ren "%IMAGE%\Windows\Boot\EFI\bootmgfw.efi" "bootmgfw.original.efi"
    copy /y "%~dp0apps\UefiSeven\bootx64.efi" "%IMAGE%\Windows\Boot\EFI\bootmgfw.efi"
    copy /y "%~dp0apps\UefiSeven\UefiSeven.skiperrors" "%IMAGE%\Windows\Boot\EFI\UefiSeven.skiperrors"

    There's boards out there that work with both modes on, they just prioritize UEFI before Legacy.
    Also, you have some eMMC memory, which you'll probably need some driver for.

    I'd try with the Free version but I'm still getting the same issue: I'm getting the initial error screen or the Starting Windows screen and nothing happens.

    I guess, if someone gives you the patched bootloader. But the tool is mega worth it :)

    Actually I looked at some places, all of them provide a key file only but it's expired.
