Help with crash Fedora Core 4

I had to do something like this yesterday myself after screwing up grub 
on my Centos box. You need to resetup grub is all.

Boot into the system using the fedora cd/dvd.

At the prompt, type "linux text expert" or "linux rescue" (without 
quotes, of course). I prefer the former, btw, and the rest of my 
instructions are flavoured that way.

When you get to the installer screens, do what you would normally do 
until you get to the part where it asks which partitioner you want to use.

Ctrl-F2 gets you to the prompt. My root partition is hda3 and my boot is 

% mkdir /target
% fsck -f /dev/hda1
% fsck -f /dev/hda3

When this completes, it means that the two partitions are in the best 
state they are going to be (assuming no errors....)

% mount /dev/hda3 /target
% mount /dev/hda1 /target/boot
% chroot /target

% /sbin/grub --no-floppy

 > grub root (hd0,0)
 > setup (hd0)
 > quit

% exit
% umount /target/boot
% umount /target

then hit ctrl-alt-del, eject the disk, and that should work.

Hope that this helps!
