Check to make sure your boot order in bios starts with your internal 
hard disk and if you have the option to order the hard disks make sure 
that the internal HD is first in the list.  /dev assigns the HDs in the 
order it sees them coming out of bios.  If you always get /dev/sdb for 
the internal drive then you can change the order in your devices.map 
file in grub, but that doesn't sound like it is the case.
