So I didn't restart the installer but I did everything manually.
Simply, mount the hard drive you have Linux on. mount /dev/sdfoo /mnt Mount special directories mount /dev /mnt/dev mount /proc /mnt/proc mount /sys /mnt/sys Chroot into the mount chroot /mnt Install grub apt-get install grub Install the basic stuff /usr/sbin/grub-install /dev/sdfoo Update the menu.lst file update-grub And you're done
