unmountable boot volume 0x000000ED on my laptop windows 7

I am in a pickle.

I was unistalling some usless programs when my laptop died & when I turned it on I had unmountable boot volume 0x000000ED (the blue screen)

If I hit repair windows it goes to a black screen with the mouse (nothing else)

Now I tried f8 & then did command prompt but after it had gone to the loading files screen it had gone back to the blue screens with unmountable boot volume 0x000000ED.

I DL windows 7 repair but how do I get it to install when I cant get past the blue screen?

Does anyone know any other key codes when I turn it on or anything?

Am I screwed?

Help!
