You probably need to specify where things are by hand.  Assuming you 
don't have separate /boot partitition, and that your root is on first 
disk, first partition, just type grub, and on command line enter 
something like this (as one line):

install --stage2=/boot/grub/stage2 (hd0,0)/boot/grub/stage1 (hd0) 
(hd0,0)/boot/grub/stage2 p (hd0,0)/boot/grub/grub.conf

If your /boot is somewhere else, change parameters accordingly.  If 
/boot is separate patition, leave /boot on first parameter, and remove 
it from all others (all others are relative to partition specified in 
brackets).  I'm not sure if you'll need to do this from chrooted env, or 
not (probably yes).
