Can you get into diagnostics (F2) or the BIOS (F10) to run a hard drive test? Odds are the hard drive has gone bad.

Again, not solved Yes I did memory test is passed & hard drive is says not installed , I can open f 10 & I did defauld setup

If hard drive says not installed then it has gone electrically dead and is not seen by the computer. Hard drive needs to be replaced.

I get cannot start up repair  I have tried re store but can't do that . Have recovery disk to go to recover to factory and ill not do that either. I got a new had drive and cannot format it. thougt that ws the problem. It says cannot find boot device Can you help me. either with the old hard drive or new one.

Where did you get the new hard drive? A new blank hard drive should just work with the HP recovery disks. The recovery disk is Windows 8.1 right? Do you have secure boot enabled in the BIOS? What happens when you boot from the recovery disk and start trying to recover? Exact messages, please.
