I have had similar results but they were caused by me adding an additional hdd which changed the hdd configuration.

On boot-up at the grub menu try editing the boot entry. It sounds like you are trying to boot an incorrect partition.

try playing with different combinations of and try to remember which partition you made root!

root (hd0, 1)

Please try:

---- If you are in a laptop you have a key of brightness adjustment (click on that to give more brightness)

-- add "nomodeset" to grub: See this link: http://ubuntuforums.org/showthread.php?t=1613132

-- If its X that its not running and you have an ATI: X doesn't start after Upgrade from 11.10 to 12.04

Installer might installed grub on usb, try to boot from usb and then re-install GRUB, by running this command:

sudo grub-install /dev/sda
