I have just installed a windows vista partition on my 17 inch macbook pro and when i insert the mac osx installation dvd in order to install the mac drivers the on the windows partition the d drive shows that something has been inserted but the cd has no name and whenever i try to click on it says nothing is on the cd. However when i insert the dvd in the mac osx partition it reads the dvd fine. Why is this? There is a scratch on the dvd but what difference would it make if the mac partition is reading it fine?
