i don't want to do a fresh install as i'd have to transfer everything to my external hard drive and lose passwords and all. i was told about doing an archive/install which sounds like the best route to take. however, the instruction guide here: http://docs.info.apple.com/article.html?artnum=107120 doesn't seem to be working on my MBP. there are no options. just install. i received an upgrade disc from apple, not a retail box. does that make the difference? either way, would like to do this the best way possible. thanks!
