New grub version needs testing

[Ernst Persson]

Boot from the install cd.
Answer all questions about languages and configure your network.
Switch to the console on screen 2.

mkdir /mnt
mount /dev/ubuntu /mnt
mount -t proc none /mnt/proc
chroot /mnt /bin/bash
mount /dev/boot /boot
apt-get update
apt-get upgrade
grub-install /dev/whatever
grub --no-floppy
    root (hd0,X)
    setup (hd0)

Yeah, that should do the trick for an unbootable system without having
to reinstall Ubuntu.
Good luck!
