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
hda1.
% 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!

Howdy,
I was installing Audacity when I encountered a total lock-up failure.
After reboot, the only thing that comes up is GNU GRUB
(grub>) I tried to reinstall off of my original distro disks using
the upgrade mode because I have gobs of files that I presently can not
get to and I don't want to wipe the hard drive clean and start over
loosing all my data. When I try to do the reinstall/upgrade I get an
error message telling me that /usr/tmp is a directory and should be a
symbolic link I should return it to the state of a symbolic link and
restart the upgrade.
Any suggestions would greatly be appreciated..
