Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

1. Turn off the computer, and then connect the power cord.

2. 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.

   

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

   • 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 section to Recover the BIOS using a USB recovery drive.

In some cases the automatic BIOS recovery fails because of corrupted CMOS (Complementary Metal Oxide Semiconductor) data. The CMOS stores BIOS settings. Try this procedure to reset the CMOS and recover the BIOS.

1. Turn off the computer.

2. Press and hold the Windows + V keys.

3. Still pressing those keys, press and hold the Power button on the computer for 2-3 seconds, and then release the Power button, but continue pressing and holding the Windows + V keys until the CMOS Reset screen displays or you hear beeping sounds.

   At the completion of a successful CMOS Reset, a message similar to the one below displays:

   

4. Press Enter to restart the computer.

Hope this helps! Keep me posted for further assistance.
