I've read how to use an existing Boot Camp XP partition in Parallels. I have a Parallels virtual machine that I need to use in Boot Camp. Is this possible? If not, and I have to create the Boot Camp partition first and then create a virtual machine, how can I use my current XP product key when installing in Boot Camp? I spoke with a service rep at Microsoft and they said that uninstalling Windows XP will deactive it so it can be installed on another machine (which would be in Boot Camp). The trouble is that the system help page for uninstalling Windows says to choose Windows XP from the list of programs to remove in Add/Remove Programs and XP isn't listed.
