Hey guys. I am new to the site, and a new macbook owner as well. My macbook only has a 120gb hard drive and I have already upgraded the ram to 4gb so before I start using it daily I want to get a bigger hard drive in it and the new Leopard OSX because I currently have the Tiger. When I get my 320GB Scorpio Black SATA 7200rpm hard drive and I install it (which seems very easy to do, almost like the same as taking out and replacing the ram), what steps do I need to do when I boot up the laptop with the blank hard drive? Do I need to put the CD in before I boot it up? Will it prompt me to do anything as it boots up? I apologize if there is already a thread on this, but I am new to the site so I don't really know how to navigate quite yet. If anyone can help me out that would be MUCH appreciated. Thanks!
