Recovering Grub

Uhu, Grub thing again.,

Now i must find the easiest solution, as simple as 1, 2 3.

1. Boot from Live CD. Install grub with the following command
   $ apt-get install grub
   $ sudo grub
2. Find the partition in which Grub is to be installed. May be the '/' partition of your hard drive, or the '/boot' partition of your hard drive. Then execute the following. Make sure you are in the grub shell with grub> prompt
   grub> root (hd0, 0) - Assuming 1st paritition of your first hard drive is the boot partition
3. Setup the grub and reboot.
   grub> setup
   grub> quit
   $ reboot
