I have struggled getting 12.04 installed. I'm doing a fresh install replacing 10.10. I have tried this twice and each time when all was finished I got a black screen. This time I downloaded the 12.04 ISO via bit torrent, and burned a DVD which all checked out. Now, I'm ready to try another fresh installation. I can still go back to 10.10 if this one fails but I'm getting mighty tired of going back and forth. Does anybody want to venture a guess as to whether this one will be successful?
