How do I load a new OS or deal with the error message.
Error code=
Boot Device Not Found
Hard Disk (3F0)
F2. System Diagnostics
For more information. Please visit www.hp.com
I have been thru the HP. generic troubleshooting B.S..
I have reseated the hard drive.
I can run a “Memory Test"
Ist dies eine gute Frage?
Does the drive show up at all in the BIOS?
If yes then your copy of Windows may be corrupted.
Can you not get into Windows Recovery?
I'm assuming you can hear the drive spinning and fans going.
Do you know that the W8.1 thumb drive is good? Has it been tried on another machine?

Usually that is due to a failing hard drive or hard drive cable being loose / damaged.
