Thanks! I downloaded it, and compared to my previous download. The sizes were identical, so the problem was not there. But I copied the image on another USB stck, and this time it booted ok! Obviously the image was somehow corrupted when copied on the first stick.
PS it tried the Enable Hardware acceleration from the Fienix Companion menu...and it broke my X desktop. It renamed by Xorg.conf to Xorg.conf.bak and i had to manualy rename it back to get the desktop back up and running.
Ok, thanks for warning...I will not touch it until Casey checks that issue. I did not yet put a xorg.conf, but the desktop seemed to work without it in machine. But I will add it as I naturally want to get the hw acceleration for videos.
I opened VLC to see how it behaves, and after I clicked the menus it froze, as well as the whole system. Reboot was the only way out. Have to test it again with 'radeon' enabled.
