GRUB assistance restoring to a second disk

view story

http://ubuntuforums.org – My root disk died and I'm trying to restore to a second disk. I had a complete dump from a couple of days earlier, so this should be relatively easy ... except for GRUB ! I'm running 12.04.2 at this point. 1) I plugged in the new external drive, which is SATA. It shows up as /dev/sda 2) I ran grub-install on sda 3) I mounted the drive, restored the complete image from the dump 4) I edited fstab in the restore, fixing the UUID to the new disk 5) I ran grub-mkdevicemap on root (the internal drive that I'm running from at this point) 6) I ran update-grub The menu entries for sd (Hardware)
