I am getting the same results are you are in your first post. I am a noob, and have been having problems with SL and Lion install. I was hoping you could help me with getting as far as you have. When I try the unishit Lion install I have no USB ports working, so I went back to SL 10.6.3, I can get 10.6.6 installed but I would like Lion 10.7.3 or higher, please help.
