To understand the problem further, some questions.

Assuming the drives were sda and sdb which is which?
As originally setup how did you select which system to boot from?  Did
you tell the BIOS to boot off one disk or the other or did you get a
grub menu that allowed you to select which one?
If it was the latter then which drive did it actually boot from to
give you the grub menu (as setup in BIOS)?
