So i went into the disc utility and was able to basically undo the partition and restore the disc to one image so that worked. And i was able to get a good install sort of but now it wont install the UDK says i need at least windows xp Service pack 3 but it has windows 7 and the service pack 1, so i dunno what to do there.. but i did get it to work at once disc but i have to cover my butt and make sure i can get my work done for school.
