12.04 - After installing Ubuntu alongside Windows I do not see the dual boot option to start windows 8.

I had Windows 8 installed on my 500GB Hard Drive and it was working OK.

I then did a clean installation of Ubuntu 12.04 partitioning Windows 8.

Now that I have installed Ubuntu 12.04 I can not see the disks partitioning when starting up my machine. I boot straight into Ubuntu.

However, when I'm logged into Ubuntu, I can see the Windows 8 partition and files in devices.

Any ideas on how I can resolve this problem?
