my pc is wired to dsl?

Question

and got a router to connect wireless my daughter's laptop, but sometimes the connection dropped and clicking the repair button usually fixed the problem, but this last time I tried to do it with the wizard following the instructions of connecting the internet cable directly to the laptop, but I didn't finished with the wizard and after that my pc looked like it had wireless connection, but with little or no connectivity, and I tried to fix the problem disconnecting and reconnecting the wires to no good. Today I turned on my pc and the only thing I see is a "Non-system disk or disk error. Replace and press any key when ready" sign. What is wrong with it???? plain language please

Answer 1

Looks like you lost your hard disc (or it got disconnected)

Answer 2

Well the two aren't related unless your hard drive is having major issues. The Non-System disk message is telling you that your computer can not read the hard drive boot track.
Before you panic, turn the machine off, and pull the power cord out for a full minute, Then reconnect it and see if you can boot. (With the newer machines turning off does not kill the power to the mother board - pulling the plug will!) If you still get the message you may need to get some professional assistance.
