You could also use Synaptic to install grub-rescue-pc which contains an ISO image [grub-rescue-cdrom.iso] that you burn to CD to create a bootable CD from. This is only 850.0 KB so it is not a large download. You could keep this image on a USB flash drive and boot it from there. For really old machines there is also an image [grub-rescue-floppy.img] to write to a floppy disk, being only 1.4 MB in size.
Both will boot you into a grub command-line environment with all the tools you need to repair a GRUB-PC installation.
