Yes, form the windows start menu, I select 'shutdown' and then confirm when prompted.
I can't help but notice that when windows boots in parallels, their is a brief display that indicates it's loading some kind of parallels profile (I don't know what else to call it) vs a 'Windows XP Home edition' profile (again, these don't show up as hardware profiles, I just don't know what to call them). When booting into bootcamp it asks which windows I want to boot (or something to that nature) and 'Windows XP Home Edition' is the only option (whereas in parallels there are two (I am locked out from selecting them in parallels).
I tried removing parallels tools and the drivers used reverted from parallels drivers to standard MS ones. But it didn't help my problem while booting into windows with bootcamp. So I am starting to wonder if there are some kind of profiles that windows uses when booting or something like that. msconfig showed these too profiles (again for lack of a better word) in the boot.ini but then came up with a message saying that the one called "Windows XP Home Edition' was pointing to an invalid windows install and asked if I wanted to remove it. Even with its removal though, it still showed up as the option when booting windows via boot camp.
I am tempted to jsut reinatall XP over the old one, but my fear is being required to call MS to reactivate windows twice. Once for bootcamp, and again for parallels. Somehow I think if I have to do it twice they won't allow me to do it. And I also fear that reinstalling windows XP while booted from bootcamp will hose my parallels install.
