    The BIOS mode has to "match" the disk type... or the computer won't boot.

    UEFI goes with GPT
    Regular BIOS goes with MBR.


    I already posted this earlier.



    This is from my BIOS... his should be the same or similar...
    Some motherboards like CSM set to enabled... some like it set to disabled.


    See Option #1, step #3... here...

    Diskpart
    sel disk 1
    sel par 4
    delete partition override
    exit

    Then let's try to bring the EFI-Partition to the end of disk 1 and reconfigure the Recovery
    Otherwise the upgrade to WIN 11 adds another Recovery at the end of Partition C

    When you deleted Partition 4

    run
    diskpart
    sel disk 1
    list par
    exit

    and: Do not hesitate!
