First timer - asking me to press button on boot up

Hi all, hopefully this is something simple. I’ve spent the time to hopefully set up my USB boot media correctly, spent a couple of hours going through the Dortania setup pages and double checked my config.plist.

After booting off the disc it goes through the verbose stages then comes up with these 2 images flashing, like it wants me to press a reset button. Has anyone got any ideas on how to get passed this?
