If you're only trying to reinstall GRUB (assuming it's already there), 
then you can do the following:

1. Get to the rescue mode
2. # chroot /mnt/sysimage
3. # grub

Assuming your boot partition is on (hd0,0)

4. > root (hd0,0)	
5. > install (hd0,0)/grub/stage1 (hd0) (hd0,0)/grub/stage2 p 
(hd0,0)/grub/grub.conf 		// this is all in one line

6. > quit
7. # exit

This should restore your GRUB to MBR. Pay attention to the device 
specification though. You wouldn't wanna mess that up ..

At the GRUB> prompt if you type "root (" and then hit TAB twice it will 
give you a list of possible completions. Choose the one that is your 
boot partition. If you don't have a seperate boot partition it's under 
the root partition. In that case all paths should have boot appended to 
them; like "(hd0,0)/boot/grub/stage1".

Instead of the long "instal ..." command you could also use the simple 
"setup (hd0)" command script; but in my experience it does not restore 
the GRUB stage2 stuff ...

Have a look at:

for more info on GRUB.
