    Hi Paul you were given false instructions by Tim. He said to use 
(hd0,0) I think it was. It should be (hd0) like that.

    Now I assume you have a working DVD drive and you can put your F7 
DVD in that and your computer will boot the DVD. Choose the Rescue 
option. When it comes up and asks what you want to mount try and mount 
the /boot partition. At least learn what that partition is called! Let's 
say it is called /dev/sda5/. In grub that is equal to (hd0,4). Make sure 
you know the right one. If you don't you will fail.

    At the prompt on the Rescue DVD type # grub. It will bring up a grub 
shell. In the shell type this using my example. Yours might be different:

grub> root (hd0,4)
grub> setup (hd0)

After the setup it should type a lot about what it did. If not your MBR 
is broken. Get a new hard drive. If yes you get the stuff, reboot and 
your system will run again :-)
