Had an issue where my speakers would make random odd static noises, and new speakers did not resolve this. So when a windows 11 prompt to upgrade the bios and some drivers I clicked Install(Bad idea!). When the machine rebooted, I was treated to a endless loop of:

8 beeps with matching flashing and the message on screen of:

"Bios corruption has been detected.Bios recovery will begin automatically when you restart your PC"

And when it restarts, I get this message with only an option to Continue Startup:

"The system bios recovery failed. Unable to open Bios image file.

A quick google search, I tried to use some combinations of Ctrl V or Ctrl B or just B keys held down while booting will supposedly load a good copy from the HD. None of that worked!

Trying the HP's Bios drivers, out of the 4 versions for my model only 1 driver would run on 8 different windows 10 and 11 computers that I had access to. Errors are either : "GENERICDRV service failed to start due to the following error:
A certificate was explicitly revoked by its issuer." Or some service would not start and the program would exit giving no on screen messages leaving only event log errors. I also tried this in a PE environment with more errors running these bios extraction software. None of the solutions to those error messages worked on any of the machines I had access to. None of the settings in the instructions existed on my machines, and the registry edits also had no effect.

I was lucky enough to find one that would run, and it only ran on a fresh windows 10 Home PC(So dont give up and try different machines). But unfortunately using the "Create Recovery USB flash drive" option, the boot loop continued. I tried all the USB ports and the Pavilion would not recognize any Bios update files. Time to take a break :(

So this morning after more googling, I decided to try something, the last option in the HP Bios Update:

"copy

Copy Bios image to any file location. (Advanced users)"

So I used a clean usb formatted to fat 32 and pointed it to that. The second this was put in the computer and when the 8 beeps finished, it restarted to recovered the Bios progress screen!

This is a very frustrating experience, and I hope this helps some of you boys and girls out.
