So I have my desktop computer which I desire to change into Linux-Powered machine, but I can't seem to install Ubuntu. First I tried with two DVD discs, it resulted with "Medium" something error after a longer while when I pressed "Install Ubuntu". Now I tried with USB Key I made with "LiLi USB Creator". But after the screen displays icon in lower part of the screen, it turns black, displays some info that progresses too fast to read it, and it leaves me with this. Frozen.
Warning, picture is huge. Can you help me?
