Hello, I have a 15 in, Unibody MBP running Leopard and am trying to perform a clean install of Snow Leopard. The steps I'm following are: 1. Insert SL DVD 2. Reboot while pressing C key, so that MacBook boots from DVD 3. After 10 MINUTES!!! I get the welcome screen, then choose Utilities->Disk Utility so that I can wipe the HD and start from scratch 4. It takes at least 8 MINUTES !!! for Disk Utilities to show up Are these times normal? I remember when following these steps on my wife's Air, response times would be much, much shorter -- although I used an external DVD drive, obviously. I know the media is not the problem, for I have tried with 2 different DVDs. I don't think there's a problem with the DVD reader/writer, since it works fine within Leopard. Any ideas?
