Messed up Grub

Good news, it's very simple to restore GRUB! Just a few lines in the terminal! I had the same problem when I uninstalled a dual boot. You didn't need to install Ubuntu on the other hard drive to do this, in the future just do this from an Ubuntu Live CD. Just follow this script.


When you get to
the desktop open a terminal and enter. (I am going to give you the
commands and then I will explain them later)
sudo grub
This will get you a "grub>" prompt (i.e. the grub
shell). At grub>. enter these commands
find /boot/grub/stage1
This will return a location. If you have more than one, select the
installation that you want to provide the grub files.
Next, THIS
IS IMPORTANT, whatever was returned for the find command use it in
the next line (you are still at grub>. when you enter the next 3
root (hd?,?)
Again use the value from the find command i.e. if find returned
(hd0,1) then you would enter root (hd0,1)

Next enter the
command to install grub to the mbr
setup (hd0)
Finally exit the grub shell
