I would like some help.

I tried to install Windows on an [B]HP Pro c640 Chromebook[/B] [B]Enterprise[/B]
After running firmware-util.sh, the machine displays nothing but a black screen.
It doesn't display an image via the HDMI port either.
Powervash (f3+Power button) restarts the machine.
I tried connecting it with a black CH341a, it didn't detect it. EZP2023+ didn't detect the W25Q128JVSM chip either.
This backup was made by firmware-util, but when compared to a bios downloaded from here, something really went wrong.
