Notebook Boot and Lockup

I had to get a new hard drive for my Probook 6560b and, since the BIOS is UEFI, I can no longer boot into the BIOS but instead whenever I attempt to I am redirected to the system diagnostic screen.  Searching around on this site led me to the conclusion that I needed to re-flash the BIOS.  I attempted to follow the instructions here: https://support.hp.com/us-en/document/c02693833 but am running into issues.

The BIOS files I am directed to (SP85528) contain an Installer.exe file that seems to be fairly old.  When I run it on a desktop computer (not the Probook obviously since it can't boot), it asks me if I want to install the EFI partition to my hard drive or a Flash drive.  I choose Flash drive and then receive this message:

"HP_TOOLS Partition cannot be found on USB Drive.  Would you like to create it?"

This is a bit scary because I have a few drives connected to my computer via USB; I clicked Yes anyway but then the application closes with apparently nothing changing.

I take the drive over to the laptop anyway and plug it into the USB port and reboot and absolutely nothing different happens.

So is there anybody out there who can give me a hint?  I'm just about at my wit's end trying to get this thing to work again.

UPDATE: Just so everyone knows, I have been trying many troubleshooting steps.  The first involved starting the computer with the windows key and B pressed at the same time.  Doing this will actually cause the computer to turn on with a black screen and the LED on the caps lock key will blink continuously (without end and without pattern).  Within a minute or so the case fan will then switch on at full power.  At this point the computer can only be turned off by disconnecting power and removing the battery (I tried to get it to turn off with the power key by holding it for up to two minutes with no response from the computer).
