So basically, I was installing Linux Ubuntu 13.04 on a dell dimension E310 with windows XP and I told it to completely delete everything on the hard drive, and basically it would spin around, go to the location screen, then give me an error message containing nothing but question marks, and I tried this a few times, but I got the same error every time. So I hit quit, quit, etc, so incouldnjust get out of it, and then it just took me to the desktop. So right now I'm trying to turn it off, but its lagging immensely. Like I thought it was frozen for about 2 minutes while typing this, then I got here :/. Please help
