This question already has an answer here:
My PC won't start after installing the latest version of Ubuntu. I press the button to start the PC and then I see the BIOS start, but after that I get a black screen and nothing is happening. I can't even reinstall Windows 7 or choose between Windows 7 and Ubuntu.
Please help. I don't want to pay for fixing this. I don't remember the hardware, and since I can't access Windows 7, I can't tell you. The only thing that I know is that it is an HP Compaq 500bmt.
