Bios is gone

[Saber-]

Hello, 

Two days ago my HP assistant showed me a bios update, and I clicked install and it downloaded and installed, and PC restarted but never booted again and stayed on black screen, I waited for about 5 hours and nothing changed, then I decided to turn off PC and turn it on again in case there is changes, but nothing changed again and I guess my bios is gone, because it failed to update itself.

I tried Win + B solution, and didn't worked.

I also tried to enter bios but none of F keys working and there was when I realised my bios is gone or deleted or broken.

Please help me if you have any solution suggestions.

Hi
Hopefully one of these documents will cover (and solve) your problem...

Turn off the computer, and then connect the power cord.
Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
HP BIOS Update recovery in progress

If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.
