Hello I just upgrade my PC from p8z77vlx to ProArt z690 creator and I do convert mbr to gpt for my existing Windows 10 21h2 so I can use uefi bios, the problem is the conversion failed and I can't boot to Windows.

Anything I can do to be able to boot and repair the gpt partition ?

Or I need to reinstall Windows ?

    Hi DevotedOne89

    To convert your Drive to GPT:, please note, this process will wipe that drive.

    At the very start of the Installation Process, press Shift + F10, or Shift + Fn + F10 to open Command Prompt

    Run this command and hit Enter:

    diskpart

    Run this command and hit Enter:

    list disk

    (Make note of the disk number you want to convert and enter it into the next command - replace X)

    Run this command and hit Enter:

    select disk X

    Run this command and hit Enter:

    clean

    Run this command and hit Enter:

    convert gpt

    Then close Command Prompt

    Yes,

    I was able to install but not the uefi one, only the mbr

    Therefore I suspect something missing from my uefi file in USB as it's showing that error screen when I try to boot my USB in uefi mode

    Hi DevotedOne89

    Did you boot into BIOS, then turn off Secure Boot and set that YSB as the primary boot device?
