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,

    Do you have access to another PC to make the USB on that?

    Hi DevotedOne89,

    No, you cannot copy the files from the ISO to a USB, you must use the Media Creation Tool, that will download the required files, then automatically create the USB and then delete the temporary files.

    Dear Dave,

    Do I just copy files from the ISO to USB or I need to do something else ?

    Thank you

    Hi DevotedOne89,

    Yes, if you create a new bootable USB, that will contain version 21h2 and will be bootable in UEFI mode.
