Re: booting problem

2020-06-03 Thread Douglas Lindquist
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.

Did you install via an USB or CD/DVD?  Did you boot the installer via
legacy boot (extlinux) or UEFI (grub2)?  It'll install the bootloader
that was used to boot the install medium.
Just further to Jonathan's questions, if the motherboard bios has indeed 
switched from UEFI to legacy you should be able to go into the bios 
settings and change it back to UEFI, how this is done depends on the 
motherboard.
It also sounds like the Centos installer you are booting may be a legacy 
installer, in which case you might be better off obtaining a live cd/dvd 
of a Centos UEFI system.

Steve
