Hello,
i have a hp desktop, that has been working fine.The other morning i woke up to it blinking, a black screen, with "disc boot error, please insert disc and press enter. I though, oh crap, dug out recovery discs, and when inserted, the screen says no hard disc found recovery cannot complete" what the heck is this?
Sounds like your hard drive has met its maker Is the hard drive seen in the BIOS? At this point I would take out the hard drive and test it in another computer.
