I booted from dvd. I used it becuase it had the uefi files on it. I used fdisk to check
the install hd. It was still set to gpt but i set it again anyway. I could not find any
way in the bios to switch between uefi and bios mode. After I rebooted the normal
settings were there but they were messed up.
I chose the Centos 8 option and I got a grub menu listing Windows followed by Fedora 31.
I had upgraded to Fedora 32 several weeks ago and no longer had Fedora 31.
