With the Hero X and the 8700K (Bios is actual)

I have in my PC a 500GB SSD (850EVO) with Windows and a 3 TB HD with Data's. No drive else!
If I go inside the Bios to the Boot option my SSD is staying on 1. place.
Second place is the HD and 3. place the IBA GE Slot (Network card)

If I deactivate in Boot the HD, because here is nothing to boot from then this works but about 30 seconds later the Bios will freeze.
Did this 2 times and 2 times the Bios will freeze.

I tested also, if I do other things in the Bios but don't do, what I described, than I have no problems in the bios.

I don't need help on this matter, because i just let the HD inside the Boot option's. Just like to report it.
