There are a few different means to attempt recovery of the BIOS

 

Try recovering the BIOS first.

 

Create an HP Recovery flash drive.

Get your previous version BIOS file from software and drivers portal at the hyper link below

https://support.hp.com/us-en/drivers/selfservice/hp-probook-450-g5-notebook-pc/17047142

 


 

After you recover the BIOS I do recommend that you change your update settings in Windows to notify me instead of keep me up to date.

If you are a Windows Insider, those options will not be available and you best option is to turn off Windows update for a while.

I suggest taking it to a PC shop.

It should help to have a PC technician to recover the BIOS. Take your BIOS recovery USB flash drive with you.

 

Recovering a BIOS is not a simple task for many people.

 

I would not give up just yet.

So removing the memory solved the issue and it was not related to the BIOS update?

 

You hadn't mentioned that you had replaced the memory before the no-post happened.

 

That would have definitely been helpful to have known for troubleshooting.

OK. 

So now we are on the same page.  😉

 

It was not a BIOS update issue at all.

 

When you update memory it is usually best to install memory that is guaranteed to be compatible and to install memory in pairs of identical DIMM modules.

 

Adding a  single module of a different brand and/or different configuration to make an upgrade may cause a no-post.
