Hey I need to reinstall Snow Leopard on my Macbook. My question is there a way to reinstall Snow Leopard on my Macbook without loosing any of my programs and folders as it did when I installed it the first time as an upgrade? I don't have an external Hard drive so unfortunately I would not be able to backup my hard drive. So just curious if someone out there has done this or knows how to go about doing it. Thanks again in advance for all your help.
