This is a laptop that used to work and has suddenly stopped working? Is it in warranty? Go into the BIOS and check your boot device order (and make sure you have nothing in any optical drive, no USB sticks plugged in etc that it might be trying to boot from)

Well, if it is telling you the hard disk does not exist, then chances are it has died.

Is the laptop in warranty? If so, start the warranty process. If not, it is probably still worth contacting HP to see what they say.

Otherwise, you need to take the hard drive out and connect it to a working computer to run full antivirus and antimalware scans on it (if it will mount)
