Last night I successfully installed Ubuntu 12.04 64-bit, and then I tried to install Mac OSX Theme following this noobslab article.
But after I installed the last thing, GNOME Tweak Tool, I ran compiz and my Ubuntu bar disappeared, then the system froze, so I restarted, and now all I see is wallpaper; no icons, no bar.
Now I'm using Ubuntu 12.04 Live CD. It's all I can use, live CD.
And one other thing, I have Windows 7 64-bit, and it's full of spyware and trojans. Can I clean it from my Ubuntu?
