Time to selecting OS on boot screen

[Peter L]

You'll need to install grub2 using a livecd.

Here is what to do:
1. Boot LiveCD with Ubuntu and open the terminal.
2. Type "sudo fdisk -l" that is an L
3. Type "sudo mount /dev/sda1 /mnt" (you'll need to check if it id sda1, thats your ubuntu partition)
4. Type "sudo grub-install --root-directory=/mnt /dev/sda"
5. Type "sudo update-grub"

Let me know what happens
