I completed the install as described below which went well. I then copied the contents of /boot/efi to /boot/efi_copy using cd /boot rsync -acr efi/ efi_copy I then installed grub2 on sdb yum install yum install grub2-efi-modules grub2-install /dev/sdb everything ran as expected with no errors. The instructions then said to test the install by powering off and swapping sda and sdb. Instead, I just unplugged sda. When I booted the system loaded straight into a grub> prompt. I powered off and reconnected sda hoping to be able to continue experimenting. However, even with sda reconnected it just boots into a grub> prompt. Anyone got suggestions what to do next? (This server is not live, so can be wiped / experimented on) On Wednesday 09 January 2019 10:30:54 Gary Stainburn wrote: > I've just finished installing a new Bacula storeage server.
