Major error, BIOS Update on Workstation Z420

Hello,

When the Desktop was updating the Bios after installing Windows 10, the pc was blocked, I shut down by the buttons and no more image.

So, the PC starts up with a black screen, the fans are running and after 1 minute the fans start running at high speed.

I assume that the bios were not fully installed when I turned off the computer and it's stuck.

So I tried several methods to reset the bios but without success.

I removed the battery from the motherboard and press the button next to it.

I've changed the place of the Jumber ( there are two with 3 pastes and one with two pastes for the bios password reset )

I put the bios on a 4gb USB stick and try every usb 2.0 port but still nothing.

I also burned a CD to see if the player supports it without success.

Does anyone have any idea how to reset the bios on this Worksation model?
