That looks like your problem. The by-id disk name may not be the same from
system to system and so GRUB can't find the disk. If you wanted to fix this
you should switch to uuids. The uuids are in /dev/disk/by-uuid/.
If you go to that directory and do ls -altr  you will see which uuid is
associated with which partition.

The same problem that grub has, fstab also has.  You should use uuids in
fstab  to indicate which partitions to mount where. For example  here is my
/ partition in /etc/fstab

 UUID=e0dcbbf3-a4fa-4a94-9ee0-c0466aa6fb9d       /               jfs
errors=remount-ro 0       1

The older bioses were simpler. The boot disk was usually /dev/hda and this
was pretty consistent from bios to bios. The newer motherboards are more
complex and hence the more complexity in grub and fstab.
