Boot failure

Hello,
I shut down my computer last night, when i tried to turn it off today i got a black screen after windows loading.... I restarted it manually, and came to the option to choose 1 of the 5 modes, (we apologize for the inconvience, but windows did not start sucessfully.....) i couldn't choose any of the modes, like my keyboard is disabled... Never faces a problem like this, so i hope someone can help me...
