How can I fix a Windows 10 BIOS update that failed?

HP 15-Cd059sa (2YK85EA#ABU)

My hard drive failed so upgraded with a 240GB SSD.  I installed Windows 10 1709 with a USB stick made with HP Cloud Recovery.  Once installed the laptop did a few updates including a BIOS update which went fine.

The laptop did not offer Windows 10 20H2 so I ran the update manually which worked.  After a few restarts to install updates, it restarted for the last time and did a HP BIOS update as before but instead of rebooting into Windows, it rebooted into a DOS like environment to updates other parts of the BIOS, ending with the boot block.  When the laptop restarted all I got was a black screen and that is how it remains.

 

I've tried Windows + B and Windows + V but when turning on but makes no difference with or without a hard drive or BIOS recovery USB stick.

 

Can anyone offer any help to get it booting up properly again as I suspect the update on the boot block may have gone wrong so unrecoverable?

 

Also does anyone know if I can get a Super IO as I can solder a new one on the motherboard to save the cost of a new motherboard?

Why did you do a BIOS upgrade? If it ain't broke, don't fix it. Unfortunately it looks like the upgrade cooked motherboard.

Windows did it both times without me asking!

I only knew it was doing it when the BIOS update screen appeared after the reboot.

Why does Windows do this without asking?

Some systems can correct a failed Bios update, if that is what happened..  You might be able to check their community or sign in with you computers info and get to their support sites..

There have been other folks that get a Black screen for other reasons.  I will see if I can find some of those.

As stated, I've tried the recovery methods quoted by HP.

What I want to know is why does Windows 10 force BIOS updates on you?
