[ubuntu] Broke my grub - I need help!

view story

http://ubuntuforums.org – First post..go easy :) I just installed Ubuntu 12.04 as a dual boot with my Windows 7. I was using the Grub Customizer to mess with the Grub menu. I changed the resolution of the grub menu using Grub Customizer from 1900x1080x8 (or 16) to 1900x1080x24. Upon reboot I can no longer see my Grub menu. I can hit up/down arrow and select the OS by guessing. Windows 7 loads fine but Ubuntu does not load. It gives some error and never boots. Can anyone help? (Hardware)
