GRUB help

[Rick Bowers]

I just installed OpenSuSE on my USB drive from my laptop. It boots 
fine -- iff the USB drive is connected. But if I try to boot with the 
drive NOT connected, I get a GRUB error.

The install never asked me where to put the boot record, so I"m 
guessing it got put in the MBR of the internal drive.

How can I fix this so my laptop boots from the internal drive when 
the USB drive is not connected?
