I have Batocera x64 v5.19 working perfectly on my computer from the internal hard drive.
I've tried updating it to v5.20 and nothing happened. It just hangs with a blank screen after Batocera.Linux is displayed on screen. Also tried installing v5.20 fresh and that doesn't boot up either. Just displays "GRUB Loading ..." with a flashing cursor and hangs.
I've also tried installing v5.19 & 20 and running from USB but it just displays Batoceria.Linux on the top left of the screen on bootup and doesn't proceed any further.
No idea why I am no longer able to install any run any Batocera versions. Any ideas on what happened and what I can do to fix?
