Hi, and welcome to FineTunedMac.
I'm afraid your question is far outside my area of amateurise, but maybe I can help by setting you up for somebody more knowledgeable.
1.
Precisely which Mac and version of OS X are you running? ("
7.1 macbook" is not adequately descriptive.)
2. Did the OS X disc you're using come with your Mac, or is it from another source? (
Edit: And which version of OS X does it install?)
3.
Precisely what are you trying to do when your disc "
keeps installing macbook air drivers?"
The answers to those questions should give somebody more knowledgeable than I a good starting point.
