Home Assistant works, doesnt boot when restarted

Hi guys! I am a big fan of Home assistant, since it solved all my problems by controlling everything i have, but i still have one problem to solve.

I am using a Fujitsu S920 running HAOS only. Since installing it everytime i restart the pc it does not boot automatically into HAOS. Everytime it boots into “Diagnostic program”. Even if in boot menu the boot order priority #1 is HAOS.

How did i solve this problem until next restart? By going into boot menu. disabling Diagnostic Program on Boot Option #2. Leaving only Boot option #1 HAOS open and disabling everything else. Save, restart, F12 and select HAOS.
Only by this way i can directboot into haos.
If i restart now it magically boots into Diagnostic Program and NOT HAOS, even if the boot order is still 1. Haos 2. Diagnostic (magically appears again).

-Secure Boot is disabled

Does someone know a solution?
