Ubuntu – GRUB2 menu only shown after Ctrl+Alt+Del

12.04bootdual-bootgrub2

After finally getting GRUB to see my win8 installment, I decided to tackle my other GRUB2 issue. The GRUB menu only comes up if i press CAD during a blank magenta splash screen that appears during boot where the GRUB menu should be. After I press CAD my computer reboots and then I can see the GRUB menu. How can I set it so that the GRUB menu always shows up?
I already tried commenting out GRUB_HIDDEN_TIMEOUT=0 and also changing the value.
I also tried changing the value of GRUB_HIDDEN_TIMEOUT_QUIET=true
