I've installed BootCamp and then Windows a couple of times now. The first time I had to format my drive and install, second worked fine and now, coming to install again, it says certain files can't be moved and I must backup, format and try again. I only want it to play a few game demos. That's it. The Console tells me nada on what's going on. Any ideas what files can't be moved? Is this a generic error or specific to each partition?
