I just recieved a new hard drive to replace my old hard drive in my macbook which had crashed. When I first got my macbook Leopard had not came out yet. I had the Tiger re-install disk. Now since Leopard has been released I upgraded. I bought just the one install disk because I am the only on in my family that has a mac. The thing is, is that since I have a new hard drive I want to install the Leopard again. I wanted to know if I am still able to install leopard even though I bought the one install. If not how will I be able to get Leopard back on my computer without buying a new Leopard disk again?
