Alright, my friend recently ran into some troubles while trying to dual boot linux on his laptop, so he's been running off knoppix for the last few weeks. Anyway, yesterday he pressed "ctrl + alt + esc" to try and kill an application's process. Instead, the screen went black and he said when he tried to boot into knoppix, it gave a ton of errors and failed to boot. I burned him a fresh copy of knoppix and he said it gives him the same errors as the last disk. Does anyone know what that key combo did? (maybe he pressed the wrong key combo). And, is there anyway he can fix it so that knoppix will boot again?
