Laptop won't boot. Says Boot Device Not Found

[RaineLark]

Computer was working fine. Did a factory reset which it never completed after 24 hours it was stuck on 3%. Now it will not do anything except show a black screen saying "Boot Device Not Found. Please install Operating System on your hard disk. F2 System Diagnostics".

I cannot get past this screen to do anything. Tried the F10 key and also Esc right at power on stage then get a small menu. When I select any option it brings me right back to the same black screen error page.

Hello @RaineLark 

Welcome !

You face this message "Boot Device Not Found" because your Windows recovery/reset has failed. You are left with no operating system running , you have no Windows operational.

There are two reasons for the recovery/reset to fail:

 - Hardware issue (usually HDD problem)

or

- Corrupted recovery partition (happens frequently due to some Windows updates)

In order to rule out why your reset failed, please test your hardware using the built-in mechanism from BIOS/UEFI -> F2 button -> here is how >>>>> https://www.supportvideos.ext.hp.com/detail/video/4330525144001/running-hardware-diagnostic-tests-us...

Perform quick/fast or run-in test, whatever is available.  Let me know the results.

Also, let me know if Windows 8.1 is the Windows version you want to restore on this device

Looking forward to your reply

Hello!

Thank you for the instructions. The laptop will not let me perform any functuon. It continues to default  to black error screen. It won't let me choose F2.

Yes, Windows 8 was the original operating system installed.

You are welcome.

• Press and hold the power-off button, and hold it for 5-6 seconds until the device powers off completely
• Wait for a while and then...
• press the power-on button once to start the PC.... but
• immediately begin hitting the Esc button repeatedly (like tap-tap-tap)
• HP Start up menu should open
• Eventually, hit F2 to enter Hardware diagnostics.

If necessary repeat the procedure above until HP Start up menu appears.

I had the same issue but was able to run the F2 diagnostics and all test passed (including the full disk check). What are my options for recovering the files on the laptop and then reformatting it?

I was finally able to run the F2 Diagnostics.  It passed both tests for the Hard Drive.  The error screen continues to say Boot Device Not Found and asks to install an operating system. It was Windows 8. How do I get it to find the files or get it re-installed?
