Your GRUB needs to be reconfigured.
At the terminal enter:
sudo update-grubThere is an OS prober that will search for other operating systems and reconfigure GRUB.
When I run it it kicks back something like this:
Code:
Generating grub.cfg ...

On a reboot all of your options should be seen.
However, I'm a big fan of a little application called
Grub Customizer...so much so that I've attached it to the bottom of this post.
With this handy little gem you can easily modify your GRUB and make it pretty and fun...as pretty and fun as a GRUB can be.
Rather than hand hack your configuration file you can point'n'click a GRUB with modified menu, splash, personalised options. I've put a copy on my Navigatrix USB stick for those times that I have buggered up my system by doing something I shouldn't have...because sometimes I do.
You can install it by downloading the file and executing from the terminal:
sudo dpkg -i /home/$USER/Downloads/grub-customizer_2.5.7.1-0ubuntu1~ppa1l_i386.deb.docIt will appear in
