I've flashed my USB drive and set my BIOS to boot from USB.
On boot batocera.linux appears in the corner for a few seconds the the screen goes blank. It hasn't powered off. How long should the first boot take to configure?

And add some more info on what hardware you are using. Also are you on 5.25 ?
