Get me back my distro safe…..GRUB re-installation

There are many cases where you lose the grub and you cannot get back in to you world..
just like windows reinstallation… partitioning the HDD.. etc .

here is a very simple way to reach you world easily.

* pop in the ubuntu live cd

* mount ur linux partition
mount -t ext3 /dev/sda8 /mnt
considering that sda8 is the partition where linux is installed

* install grub

grub-install --root-directory=/mnt/ /dev/sda

* restart the computer and you will see the Grub back

sda is basically for sata drives..

for older drives it should be hda, hdb etc.. and for special devices it should be sdb i guess..

thanks to Jain johny for the clue.
