Hi, I have an 80 gb macbook (pre sr) and I want to upgrade the HDD to at least 160gb. I can do this myself but I just have 2 questions. 1. I don't want to clone my hard drive I would rather start from scratch. So to do this do I just boot the mac up after installing new HDD with just the leopard disc in or is there more to it than that. 2. When I re-install my software (MS Office etc) will I still be able to use the original product keys or will I ust have to clone my HDD. Sorry if this is a repeated thread, I tried looking for this in other threads but couldn't find the specific answers I needed. A big thank you to anyone who helps.
