mac OS X Leopard Installation CD


Hi, I have installed the OS X leopard from a family pack after erasing OS X 10.3.9 (which I absolutely regret at the moment) and installing anew.

Apart from a 101 problems post installation, I have to return the disc to my cousin who is leaving the country, so I would like to know if there is anything on the installation disk that I need or can save for future usage / problem solving before returning the disc and not having access to it again?

many thanks. :)
