Hi:

It is very easy to update the BIOS and not be using W10 to do it.

You don't even need a hard drive installed for that matter.

You use the F10 Setup BIOS Flashing method.

This appears to be the latest BIOS update HP released for your PC:

v2.03:

Ordinateur HP Compaq 4000 Pro à petit facteur de forme Détail des logiciels et pilotes

Get a USB flash drive.

Format it with the FAT32 file system.

Download and run the above 2.03 BIOS update file.

An info page will open.

Look for the instructions listed under the F10 BIOS Flashing section.

At the bottom of that section, there is a blue 'View Contents of DOS Flash Folder' link.

Click on that link and copy all of the files in that folder to your USB flash drive.

Just the files, not the folder itself.

After the files have been copied to the USB flash drive, restart the PC.

Tap the F10 key to enter the BIOS setup menu.

Select the File tab>Flash System ROM command.

Select the USB flash drive.

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

Follow the on-screen prompts to update the BIOS.
