Solution 1:
    Leave it alone.

Solution 2:
    Assuming that hda1 and sda1 are the root partitions.  Boot from some
    live CD or USB key.

    mount /dev/sda1 /mnt/new
    mount /dev/hda1 /mnt/old
    cd /mnt/old
    cp -ax . /mnt/new
    chroot /mnt/new
    lilo	(or grub-install /dev/sda)
 
    You may need to create /dev/... in /mnt/new.  Rinse and repeat.
