How to do clean install and install lion
Hello
I have snow leopard installed on my MBP and have time machine too, connected to my external HD. I would like to install Lion OS today. However before I do this. I would basically like to do what some people say is a clean install and then install Lion OS. However I do not want to lose all my information that is stored on my MBP either. What is the best way of doing this? Should i simply put all my files on a DVD and then install everything once I have done a clean install and got Lion on my MBP? How does one do a clean install and what does it actually do? Or should I not back up everything on DVD, and then simply do a clean install and install Lion OS and simply connect my external HD to my mbp and get my information via time machine?
Hope someone can help.
Thanks
