Reinstall Ubuntu Grub Bootloader After Windows Wipes it Out

Following is the way and it was work for me.But you have to have a CD Rom and live CD for ubuntu.

Note: when you use terminal,tab key will help you to hit the command properly.

Note: root (hd0,0) --->parameters of this command will change accoding to your installation and computer disk. tab key will help you to find it.

1) Boot off the LiveCD and go to terminal

sudo grub

root (hd0,0)

setup (hd0)

exit
