However, when I try this I get: [root@lou ~]# grub2-install /dev/sda /usr/lib/grub/x86_64-efi doesn't exist. Please specify --target or --directory [root@lou ~]# A quick google shows gives the indication that this is for MBR systems where mine is UEFI. A slower google hasn't given me instructions on how to do this on a UEFI system in a way that I can understand. Can anyone give the equivelant to Bill's commands above. To review the situation. I have sda which I boot from. I have a brand new sdb which I use for RAID1. Should sda fail at some point I want to be able to unplug sda, and be able to boot from (what is currently) sdb. this is what the two drives both look like at the moment, [root@lou ~]# parted GNU Parted 3.1 Using /dev/sda Welcome to GNU Parted!
