Not able to boot Fedora 2 after ghosting X

[Greg Geist]

[snip]
 If you boot off "disk 0" and that device is
"hda", "grub-install /dev/hda" will install grub on the mbr of your boot
device. If your boot device is other than "hda" use the appropriate device
name (hdb,sda..etc.)

>this also works, when you boot from the rescue-cd from fc2?

Yes, it does. The grub-install manual pages provide details and some
how-to's make use of the technique to re-install grub to alternate
locations.
