When I boot up my macbook pro, it tries to boot into windows first rather than OS X. However, I haven't actually installed boot camp. I tried to earlier today but when it came to formatting the drive it failed, so I canned it and made the drive back into one whole partition. However whenever I boot it comes up with the black screen and white writing that says something about inserting the removable media (I'm guessing this is the XP disc.) I've checked on disk utility but the HD is one whole OSX partition, and also when I boot up and press command the only thing that comes up is the Macintosh HD.
