I have dual booted xp and vista before without a problem, my question is can I dual boot Win7 and Vista 64? If I do this, which one do I need to install first? If I want one of them to boot as default, how do I do this? and if I want to change which ones boots as default, how do I change it? Can you see a dual boot causing problems? (I have 5 HDDs that will be accessed by both) If I wanted to remove Win7 but keep the Vista (I would do this when and if my Win7 expires) can I delete just the win7 and keep the vista? Or the other way around? Thanks for the help!!
