USB booting :: Wont work right

Edit

Ok. I did the install, took about 30 minutes, and now when i reboot it boots, but doesnt even give me the blue screen asking for me to press enter. It goes through the normal boot, and then just gives me a black screen with a flashing underscore. If i press control+alt+delete it restarts. Also, every time i press any other key it beeps.
Help?
