Is this what you were looking for?  You may have to go into your MB BIOS and set it up for UEFI booting.

Thanks, Frank

Bios is locked with a password (unfortunately).
So what I know is that I can boot with UFI in secure mode. But I don't know how to get the Unraid boot in secure mode. 

What I get now is "Selected boot image did not authenticate" what is saying that I have to boot UEFI secure mode.  I set the flag for UFI when I make my USB drive.

Thanks for reaching out 🙂
