Somehow, my previous post did not make it to the list.

Anita is right if grub's integrity is ok.  In my case, I often simply 
change the number of the partition and root until the system boot 
(partition numbers change when you repartition a drive).

You can use the shell in Grub to search, edit, and boot the system 
manually. It's pretty neat, in fact.

But if Grub can't find its own files, then you have to modify the MBR to 
point to the right place, and to my (limited) knowledge, you have to 
reinstall grub, which you can do, in your case, with the debian install 
disk.  You have to get to the Debian installer main menu (I do this by 
escaping a regular install, as I don't know better), and pick the 
"Install the GRUB boot loader on a hard disk".
