Just bought a new MacBook Pro laptop and need some help please. My question is, my hard drive is 320gb (280 after installation). I can only seem to be able to use 150 gbs of this drive. I am trying to reinstall Tiger and then upgrade to Leopard. When I insert the Tiger CDs, it only prompts me to reinstall on a fresh 150 gbs. I am at a lost one how to reinstall freshly and get the 280 so I can use that to split Leopard and Windows XP. In other words, how would I completely erase the hdd and get the 280? Thanks for your help.
