I dual boot with Xp and Vista. All you need do is install XP first (which i
assume you already have this installed). Next create another partition on
the same drive (or another drive if you have one) and then install Vista.
After installation, when you reboot the machine, you will have a menu
appear giving you the option to boot into Vista or XP.
As has already been mentioned when you are using XP then XP takes the C:
drive letter and Vista becomes D: (or whatever letter it has assigned)
conversely when you boot into Vista, Vista takes the C: drive letter and
XP becomes D etc.
The only major problem is XP's shadow copy facility. When you boot into XP
windows XP will immediately delete 'all' system restore points created in
Windows Vista ( i believe it also deletes shadow copy files for Complete
PC Backup if you are using a version of Vista that supports this, i.e,
Ultimate)
A third party boot manager should solve the problem of losing restore
points from Vista. Alternatively, if you are using Vista Ultimate or
Business, you could use Bitlocker encryption to prevent the restore points
being lost. Personally system restore is disabled on both my XP and Vista
partition so the thought of losing restore points ins't one that bothers
me, but it may bother you.
