The commands are:
1) Try to mount the partition where you have installed ubuntu, hope you
know by its number, let it be sdax
$ sudo mount /dev/sdax /mnt
2) chroot into this directory
$ sudo chroot /mnt
3) Now open grub inside the chrooted environment
$ grub
4) Try to find where GRUB is installed
grub> find /boot/grub/stage2
5) You would get some output like (hdx,y) which means GRUB is on hard
disk hdx and partition number y
Now type the two commands
grub> root (hdx,y)
grub> setup (hdx)
And its done.....
hdx should come to hd0 in most of the cases. Please ignore "$" and
"grub>" wen typing the commands, they are just shell and grub prompts
