I've had ubuntu for about two months and its worked flawlessly but yesterday when i booted it up I got a screen that said Grub 1.99 (Grub Rescue screen)

It asks to hit tab to display commands except for none of the commands work.

Someone please help me get ubuntu booted and running again!

Please edit your question to add details as to what caused this grub rescue screen and what have you tried so far. Have you tried booting to a liveCD and reinstalling grub? –  Peachy Oct 7 '12 at 5:33

You should really provide some more information of what you had been doing prior to the grub problems. Are you having another operating system(s) on your computer? Did you try typing those commands to see that they're not working ?

I do have windows running as well on my computer, but i haven't touched it for a while. I also did try typing the commands but none of them provided a response. –  Nathan Sep 24 '12 at 21:36
    
It's possible that it somehow got messed up since you've also got windows on it. You should try reinstalling grub, here's how to do it. You'll need a Live CD/USB. –  Maputo Sep 24 '12 at 21:43
