Hi Jim, Thanks for this. I looked into what you said, and once happy I ran the command you gave. It appeared to work as it did not come up with any errors, and the output from efibootmgr showed 1) Centos had been added as an option and 2) it was the first in the boot sequence. However, when I rebooted the laptop went straight into Win8, and after rebooting back into KDE Live, the option is no longer there. This is the output after rebooting.

I don't know if this additional information helps. Looking at he efibootmgr
output, is the centos entry pointing to the right place?
Also, any idea why the update isn't being make permenant?

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?

But notice the boot order: BootOrder: 0003,2002,0002,3002,0001,2001,2003 That puts Fedora in 5th place. You need to use efibootmgr -n 0001 to do a one time boot of Fedora at next boot; or you need to use efibootmgr -o and explicitly change the entire boot order, separated by commas. I have no idea what RC at the end of these lines means though. -- Chris Murphy
