I recently tried to install Centos 8 on my 3tb uefi hd that already had Fedora 32 and Windows 10 on it.  The Centos installation did not finish because it could install the boot loader.  It ended up screwing up the uefi boot because it will no longer boot to anything.  It looks like the bios reset  to non uefi boot only.  My mb is Gigabyte B450 Auros with 64gb mem.
