I tried to upgrade from 10.2 to 10.3 and ran into problems with grub on 
reboot.  I found that the grub entry was
root (/dev/sdb1,0)
I didn't have a clue as to what was going on but my colleague explained that 
this syntax was foreign to grub.
replacing the entry with:
root (hd1,0)
did the trick. If I understand correct the grub entry "hd1" refers to the 
second disk (as the grub count starts at 0) and the "0" refers to the first 
partition.

Hope that helps
Eddie
