Hi,
tried upgrading bios to latest version (F.54 Rev.A) via windows. Once computer rebooted, I started getting the error which is shown on the first image attached.
Created bios recovery USB stick on Windows via the menu provided by the same exe as the bios update, but no luck. Get the message, computer restarts and the screen stays blank. If I leave no usb stick inserted after showing the initial error it restarts and shows error shown on the second image attached.
