    The first thing you should do is to get a livecd, for example the gentoo livecd or knoppix... Then you mount the linux partition to, lets say /mnt/linuxdistro and chroot into it:
    mkdir /mnt/linuxdistro
    mount -t ext3 /dev/hda2 /mnt/linuxdistro
    mount -t proc none /mnt/linuxdistro/proc
    mount -t ext3 /dev/hda3 /mnt/linuxdistro/boot    [color=red] #ONLY if /boot is on its own partition[/color]
    chroot /mnt/linuxdistro
    ^^ Replace "ext3" with the filesystem of the root-device, and /dev/hda2 with your root-device. The same info about /boot must be replaced if you have /boot on a seperate partition.

    I've been using LILO lately so I can't say som much about grub, but here's at least how gentoo docs describe installing grub:
    grub-install /dev/hda
    Replace hda with the harddrive you're installing grub on.
