Hi! @AymanPT, Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!

I understand you get a black screen after the BIOS update on your PC.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Are you able to boot into BIOS?

Please provide the product number of your PC to assist you better.

As you mentioned you get a black screen after the BIOS update on your PC.

Try few steps recommended below.

To perform a power reset on a laptop with a removable battery, use the following steps:
Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.
Your laptop has been reset. After a power reset, it is a good idea to run Windows Update and HP Support Assistant to update all device drivers. See Updating Drivers and Software with Windows Update (Windows 10, 😎 and Using HP Support Assistant (Windows 10, 8, 7) for more information.

After the reset try the steps recommended below.

Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key and the B key at the same time.
   NOTE:
On some notebook models, it might be necessary to press and hold the Windows logo key and the V key.
While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key  and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).
The HP BIOS Update screen displays and the BIOS update begins automatically. This might take several minutes, and you might hear additional beeping sounds.
If the HP BIOS Update screen does not display, repeat the previous steps. If the issue persists after repeating the steps, skip to the next step to Download a replacement BIOS file.
If the Power light turns off, the notebook has turned off because the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for 2 to 3 seconds only.
If your notebook starts Windows, update the BIOS to the latest version using the standard BIOS update procedure. For more information about updating your notebook BIOS, go to Updating the BIOS (Notebooks).
Click Continue Startup to prompt the notebook to restart immediately, or allow the notebook to restart automatically when the timer reaches zero.
After the notebook restarts, press Enter to continue.
   NOTE:
If the notebook repeatedly displays a message that the BIOS has been recovered, go to HP BIOS Application Selected is Corrupt or Missing for troubleshooting steps.
After Windows starts, if a message displays stating that the notebook was improperly shut down or that a boot problem was detected, follow the on-screen instructions.
You can now to enter the BIOS menu or start the Windows operating system.

@AymanPT, Thanks for your quick response and time.

I appriciate your efforts for writing back to us.

As you mentioned the issue still persists after trying out the steps.

Are you able to boot into BIOS on your PC?

If you are able to boot into BIOS try restoring the BIOS to default and check if it works.

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.

@AymanPT, Thanks for your quick response and time again.

As you mentioned when you access BIOS on your PC you are getting a black screen on your PC.

And you cannot create a USB recovery on your PC. You have to download the BIOS on a working PC and create a USB BIOS recovery.

Once after creating the USB recovery kit, you can connect back to the non-working PC and recover the BIOS.

If you still have issues booting into your PC.

It is a hardware issue with your PC. Please contact HP support for service options.

If the solution provided worked for you, please mark accepted solution for this post.

Hope this answers your query!

@AymanPT, Thanks for your quick response and time.

To answer your queries you can download the BIOS for your PC using this link.

And you need not use an HP PC to create a USB recovery.

Yes, the BIOS update can fail if the BIOS update was incomplete or corrupted.

You can create a USB referring the video from my previous thread.

If the issue still persists, please contact HP support for service options.

Let me know if answers your query!
