Looks like it can't find the system software.

I think this is similar to Roofmonkey's help.

Took it to my closest apple store yesterday since I was in the big city. Had a 320 Genius Bar appointment, and arrived at 1:35 or so. Got me in Around 215. Said he thought it was just a bad connection cable. $96 to do the repair. Called me about 430 and said they also found out that there was some level of corruption to the operating system installed.. So they replaced the cable and got everything booting correctly again. But tonight, I will just need to do a back up and then reinstall the operating system and restore. Picked it up last night.
