I am preparing to replace the original 40gb HD with a 250gb HD. I am unfamiliar with the process of doing a new Install of OS X Tiger. Do I just insert the install DVD onto the machine, and let install DVD guide me through the install, including formatting the new drive? Or is it more complicated than this? Will f12 still work to eject the optical drive without any OS present?. I want to get this done within the next couple of days or so, as I am starting college, and will be needing it for schoolwork. I know I could probably clone my current install, but I just would prefer to do a brand new install on an unformatted drive. Any help with procedures on how to do this would be greatly appreciated....
