Need to load osx without cd

I have a friends macbook pro because they asked me to reload osx onto it since someone had messed up while attempting to set up windows xp on dual boot. I think this will be easy but something is wrong with the front of the computer where the cd is inserted. It seems to be smashed and i would have to force a cd into it and probably would never get it out. So is there a way to reload the os without the cd drive? Or does anyone have any suggestions to help me around this dilemma?
