Step 2.Open the terminal and enter this

"grub-install -v"

This will show the current version installed on your computer system i.e.,GRUB 2 should display a version number of 1.96 or Legacy GRUB is version 0.97.(Their is no need to do this step to all those who use the latest version of Ubuntu after 9.10)
