Any computer-savvy gentlemen among us?

My dell latitude is giving me a no hard drive detected error message when running diagnostics. I'm not the smartest guy in the world, but I assume this might be a bad thing. Now when I turn it on, I get a black screen that says, among other things, "no boot device found. Press any key to reboot...". When I press a key, it reboots to the same screen and message.

Any help is greatly appreciated.
