update-grub

It is putting in the UUID for the boot partition and not the / (root) partition.

It's grub2 (1.99-21ubuntu3.1) on Xubuntu 12.04.

UPDATE: ? I ran Boot Info Script 0.60, here are results?

The boot info script is too big for askubuntu, but is here.

The system not booting is on /dev/sdh. The booted disk, Xubuntu 12.04, is /dev/sdb.

/sdh2/etc/fstab is at line 1073.

The incorrect UUIDs are at line 945 and 954.

"blkid" putput is at line 318.

It is putting the UUID for "boot" versus "root" in boot.cfg, line 937.

I have noticed that the relationship between physical drives and names in /dev vary depending on which system is booted.
