[ubuntu] Dual Boot Grub2 Not Working

view story

http://ubuntuforums.org – I just bought an Asus K55N and I want to dual boot Ubuntu 12.04 x64 with the factory installed Windows 7. I used the live-cd. It partitioned the hard drive for me, but when I restart it goes straight to Window7. When I look in the bios, it gives me the option to boot from dvd or Windows loader. I have been running Ubuntu for years now and have installed a dual boot on several machines. I have never seen the grub gui not appear. If anyone has the time, I would greatly appreciate it. Thanks.
