Make the surviving drive primary.  Boot linux rescue from cd, allowing 
it to find and mount your filesystems, which it will do under /mnt/sysimage.
chroot /mnt/sysimage
grub install
exit # the chroot shell
exit

Boot normally.

Of course then you still need to re-establish mirrors on a new disk.  If 
you need help with that too let me know.
