The way that I have found that is easiest is just to run grub itself.

% grub --no-floppy

root (hd0,0)
setup (hd0)

*or*

 root (hd1,0)
setup (hd0)


Assuming that you only have two drives, and they are both partitioned 
with /boot on the 1st partitions...

If they are the both linux drives, then it shouldn't matter if you do 
both. Otherwise, the easiest way would be to remove the old drive from 
the system, and boot from the install CD.

Hope this helps!
