The things I can come up with are:
1. I download the installer from the App store and create the USB on a hackintoshed Probook and not on a real Mac. But I believe others are in the same boat. Or am I the only one?
2. There is something wrong with BIOS settings.
I created the USB several times now, following steps 2a and 2b in post #1....
