So I am new to all of this. I have never dived into computers this much so I thought that I would give it a try. I am trying to split my hard drive with mac osx and ubuntu. After a while of trying things and almost killing my computer (i had a back up cuz i knew that that could happen) I did it. or so i think. I am running both systems but my ubuntu seems incomplete. I can not access wireless, and all of the things that i try to tweak dont work. I think that I have done something wrong. Now i am trying to do the same thing over again, by installing ubuntu over itself. As i go through the directions to do this online it says that i need to convert my ISO files into IMG files and i cant do it. This is what brought me to finally posting a help question. I guess i dont really have a question but i cant get anything to work. can someone help me along in this process?
