Hi everyone !
I’ve got a brand new motherboard H270M-ITX/ac.
But I can’t boot anymore.
In a first time I try to boot on a usb key, sometime I can but I often can’t.
Now I try to reinstall my os but I can’t boot on my usb key.
So I try to flash my BIOS with ASRock default tool,
next that it boot only on a screen : “select UEFI boot“ but my keyboard are not detected anymore so it select automatically my old os partition.
Finaly my screen is not working anymore …

Someone have an Idea ? I’m a little bit lost …

Hi fedemengo,

I tried to change port but I've got only one keyboard.
How can I check the graphic driver ?
Do you know if it's possible de manage bios from the debian console ?
