[ubuntu] Latest release is not installing GRUB when install is complete?

view story

http://ubuntuforums.org – Just tried to install Beta 2 on my desktop and dual boot it with Windows. At first it never detected that I had two drives in the box. I pulled the power on the 2nd drive so that it would only see the 1st drive that has Windows. It installed just fine but when it rebooted it went right into Windows and never gave the option to boot into Ubuntu. Tried this a few times any reason why it's not installing GRUB? (Hardware)
