All of the following is still under the Centos 7 KDE Live CD: If I mount /dev/sda2 on /media and have a look, this is the valid EFI filesystem, including the Fedora and Centos entries. If I try to mount /dev/sda6 on /media it looks to be a valid /boot filesystem. If I mount /dev/sda6 as /boot and mount /dev/sda2 as /boot/efi before running Jim's efibootmgr command will I fix the problem or will I stuff it beyond all recognition?
