I installed Boot Camp and windows xp pro on my MacBook Pro. If I hold down the option key and select OS X or windows it works just fine. If I just press the start button and do not hold down option, the machine defaults to start in windows. This is very annoying as I only use windows periodically and do not want to have to hold down option/select OS X every time I start the machine. Does anyone know how to set it up so that the MacBook will default start into OS X? Thanks!
