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.
