    I think the scanpolicy is ok because I put that same USB stick to my PC and everything is visable and I can run instalation. HP uefi is f*** up I think and OC can’t properly scan for disk. Only HP user know what I meen.

    Same problem with my probook 6470b. Do you resolve the problem? OC USB works fine when I plug to the PC. Install, recovery, everything is ok. But on my HP is like on your picture. When USB starts auto I’ve got only black screen. I must choose Boot from Efi and than boot from Boot.efi and only then I can see oc bootmenu but there is No Instalation image. Can someone help with this?
