Just updated the BIOS on our 14-month-old Pavillion desktop. (Late June 2018 dated BIOS).
We used the HP site, and got TO the updated BIOS by entering the PC's correct serial number.
The BIOS download which came up verified that our machine IS the right model and also a "81B4" variant.
The BIOS update (an "EXE" file) downloaded. The directions said to run that program (from within Windows).
The next screen showed the old BIOS being erased,
and then the NEW BIOS (a blue bar chart) being written,
AND finally, NEW BIOS being "verified." The bar charts completed, the screen said: "BIOS UPDATE SUCCESSFUL."
Then the machine rebooted and IS TOTALLY STUCK on the HP logo.
Pressing any key (including <ESC> to enter BIOS setup and/or <F10> to enter BIOS setup (both on the HP site)
brings up a black screen with a white list of the hardware and ALSO the new BIOS "verified as installed."
We tried all the HP site's "BIOS restore" tricks. ALL OF THEM (including turning off the machine with <Windows> KEY + V, turning it back on with <Windows> KEY + B, and also creating a USB BIOS recovery stick. NOTHING WORKS.
Has anyone else had this INSANELY ANNOYING thing happen? I suspect a bug in the BIOS update.
Do we now have a Landfill Object (i.e. a motherboard fried due to a calamatous BIOS BUG?)

Power-off the computer.
Disconnect the AC power.
Press-and-hold the ON/OFF button for 15 seconds.
Reconnect the AC power.
Power-on the computer, and enter BIOS SETUP.
Does it list the disk-drive & CD/DVD device as "detected"?
Select "Load BIOS defaults".
Is there a "Boot Devices" section, that lists the disk-drive? If not, "add" the disk-drive as a bootable device.
Save/Exit from BIOS setup.
Did this help?

Thank you for your effort, but I had carefully tried exactly that sequence. Getting into the BIOS after reboot is still impossible. Have just ordered a GOOD brand motherboard of the same specs. Leaving "HP-LAND" for a decent system.

Getting into the BIOS after reboot is still impossible.
Power-off the desktop computer.
Disconnect the power cord.
Open the side-panel, to access the inside of the desktop.
Disconnect the data and power cables from the disk-drive.
Reconnect the power cord.
Since the computer cannot automatically boot from the non-accessible disk-drive, can you now enter BIOS SETUP?
