Boot from the CD/USB flash drive from which you installed Ubuntu
Open terminal (It is there under Accessories)
type in sudo fdisk -l
then type sudo mount /dev/sdAB /mnt , where A is your drive and B is your linux partition. In my case, I typed in sudo mount /dev/sda7 /mnt

install GRUB again by typing this sudo grub-install --root-directory=/mnt /dev/sdA , where A is your drive. In my case, I typed sda

Now type sudo umount /mnt
