What do the prompts on my laptop mean when booting up?

Episode 882 (1:30:33)

Benny from Pasadena, CA

Benny is having trouble getting his computer to boot up, and keeps getting prompts. One is "media test failure, check cable" and the other is "exiting Intel boot agent, insert disk in drive, press any key when ready".

Leo says it's saying that it doesn't see a hard drive there to boot to. When that hard drive fails, then it tries to use the Intel Boot Agent to boot over the network or find some other boot device. So the main hard drive has failed. It could be a number of things, but most of the time it means a boot file or boot sector isn't able to be read. He can try another drive, but he shouldn't get rid of that drive quite yet because he might be able to recover it.
