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

    Boot Option 1 on the Boot tab is set to boot form your internal hard drive (Windows Boot Manager) can you set that to the USB?

    Hi DevotedOne89

    Please provide a photo of all the tabs you have in BIOS, so I can see the available settings.

    Hi DevotedOne89

    Check in BIOS to see if CSM is enabled, if it is, turn that off.
