Here is my problem. I have a mac lap-top. It's pretty new (snow leopard 10.6) I have recently partitioned my hard-drive and installed windows xp on my other partitioned half. However, I wanted to re-boot via the apple start-up disk, again. If I do this, would I need to reinstall windows xp, or could I just hold down 'c' and re-boot via my apple start-up disk without a problem? I know I might loose the things on my windows xp, but that is not relevant. I would just like to know if I need a windows xp disk again, because I cannot find mind. Thanks!
