Hello and welcome to PROnetworks maarten_s! It is true that if you delete the Vista partition that VistaBootPRO will still stay installed on your XP partition, if you installed it there, however, it will no longer run if the place where the BCD data files were also deleted from the "System" drive, which for most in a dual boot scenario is on the XP partition. So yes, VistaBootPRO will run, but you can't really do anything with it until you reinstall Vista. Hope that makes sense; BTW, could you please stop by our
Introduction Area so we can give you a PRO welcome! Enjoy the site!
