I can't update bios

[Arthsw5]

I can't update the bios on my HP Compaq 8000 Elite SFF (HP 3646h mobo).

I downloaded the “ROM Firmware for HP Compaq 8000 Elite (786G7)” from the BIOS section of the following page: https://support.hp.com/us-en/drivers/hp-compaq-8000-elite-small-form-factor-pc/4065894

I opened the file and followed the on-screen instructions, then the progress bar reached 100% and the window closed. I restarted the PC and went to msinfo32 to check the BIOS version (to see if it had been updated) and the old version was still there.

How do I update the BIOS to the latest version?

TIA

This is the latest BIOS update:  v01.14 

HP Compaq 8000 Elite Small Form Factor PC Software and Driver Details

Check your PC to make sure it isn't already installed.  Usually, the BIOS version shows up when you first turn on the PC.

If you are not at v01.14, try updating the BIOS using the F10 Setup BIOS flashing method and not the Windows based flashing method.

Get a USB flash drive. Format it with the FAT32 file system.

To update the BIOS using the F10 Setup BIOS flashing method, run the file from the link I posted above.

An information page will open.

Follow the instructions under the F10 Setup BIOS Flashing section.

Click on the blue View Contents of DOS flash folder that you see at the bottom of that section.

Copy all of the files in that folder to your USB flash drive.  Just the files, not the folder itself.

Restart the PC.

Immediately tap the F10 key to get access to the BIOS setup menu.

Select the File tab>Flash System ROM command.

Select the USB flash drive.

The PC will 'see' the BIOS files on the flash drive.

Follow the on-screen instructions to update the BIOS.

You should be prompted to restart the PC after the update is completed.
