Hi, im new to mac so I dont really know much any help will be great. I bought a macbook pro 15 (mid 2009) from some one. I wanted a clean start. So what I did was boot from the the install cd and it had two distentions bootcamp and the other was untitled, so I zero formatted the hard drive. Selected the hard drive with the long name and numbers and hit erase took about 2 hours. Then I rebooted and when I go to chose the distention disk for installing mac os x there is nothing there, none of the two I saw before. Did I do something wrong and how do I install the operating system. Any help would be great and thank you in advance, gary.
