I have OpenSolaris/Ubuntu/pre-installed vista on my HP laptop.
OpenSolaris GRUB is installed on MBR. Ubuntu GRUB is installed on the
first sector of the Ubuntu /root partition, not MBR. And the OpenSolaris
grub menu looks like:
title OpenSolaris 2009.06 117
findroot (pool_rpool,1,a)
bootfs rpool/ROOT/opensolaris
splashimage /boot/solaris.xpm
foreground d25f00
background 115d93
kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS,console=graphics
module$ /platform/i86pc/$ISADIR/boot_archive
title Windows
rootnoverify (hd0,0)
chainloader +1
title Ubuntu
rootnoverify (hd0,5)
chainloader +1
So the basic logic is to use chainloader to load Ubuntu's GRUB from
OpenSolaris GRUB.
For your case, I think a possible way is to recover the Ubuntu GRUB with
Ubuntu liveCD:
mkdir /mnt/root
mount /dev/hd? /mnt/root
chroot /mnt/root /bin/bash
grub-install /dev/hd?
Hope this help.
