I got a problem. I have to load the safe mode for installing Steam after a crash. So I entered the advanced boot menu and chose Safe Mode with Networking. It started loading some .sys files. After a lot (I think it was loaded correctly) of .sys files my screen froze and after 3 seconds some weird blue dots appeared and (Left upper corner. Every dot was like 10x30 pixels) after some more seconds my screen turned black. No cursor, no login screen. How can I log in to the safe mode?!
