1) Make three partitions, one for each OS, and install one OS on each.
2) Each time you boot, you should have a choice of all three OSs.
3) If you want to keep XP you have to do clean installs to new partitions,
no upgrades.
4) I doubt it. But I've never done it so I don't know for sure. Intuitively
though, there doesn't seem to be any reason why it would matter. They're
three separate OSs. Someone who has been there might tell you otherwise.
