I am using an old Z420 workstation as my home network file server (NAS) running the UNRAID solution.
UnRaid is a Linux based solution which only boots up from a USB flash drive.
I've updated my BIOS workstation to the last version (3.95A) and have been trying all possible bios settings regarding boot and USB ... But up to now I was UNABLE to make it boot from the flash drive attached to the rear of workstation (yes I have tried different ones as well including at the front) without a manual keystroke.
When I leave the system to boot by itself (as it should be) it always ends up on a completely empty screen with nothing else than cursor blinking. (no error messages or anything else)
In order to make it work I have to press F9 (Boot menu) during POST and then point the flash drive... and then it works perfectly.
I have tried everything I could've think of... Including setting up Unraid to boot as UEFI or Legacy and apparently it does not make any difference. So far I could not figure this out.
What can I possibly doing wrong here ? Any ideas? Any help would be appreciated.
Thanks in advance...

i would guess that your usb key is the source of the problem
i have a z800 and a z820 (the 820 uses almost the same bios as the z420) and i have auto booted both using a usb key based nvme pre loader (DUET/REFIND) which boots from the usb key first
and it works with or without a keyboard attached
