hi guys

well as the title pretty much says
i load it from a usb (i been able to boot it on other occasions)
it loads verbose

then the wallpaper of BT5 shows up and thats it
nothing happens

(i also had once that the screen stayed black but i could login blindly and then it showed)
i also tried this but no effect

so i'm pretty sure it just freezes for some reason on that point

does some1 know what the problem might be?

thx in advance
