So I'm aware that you can install a new HDD into a MB, and once the OS install is done use the migration assistant to transfer the information/programs/settings over. My concern is that I got a new HDD for my late 2008 2.4GHz unibody MacBook for Christmas and it has Snow Leopard on it. The problem is that I have no idea where my Snow Leopard disc is, but I do have my original install discs. Is there anyway to transfer the Snow Leopard install and my programs/documents onto the new drive? I know cloning is an option, but I really don't want to buy anything if possible and want the transition to be as clean as possible. Can I create a Time Machine backup on my external and just restore that?
