When you install 64 bit Windows as a dual boot it automatically installs a
boot manager. On booting the computer you'll get a screen appear for about
15 seconds offering you the choice of which OS to boot, with one of them
being the default if you're AFK. You can alter the options a bit from within
either version of Vista from the Advanced system settings - Startup and
Recovery. Or you can install a 3rd party boot manager to do much the same
thing but with more flexibility and some repair options in case they are
needed. Quad booting XP, Vista, and 2x Win7 partitions. I'd recommend
imaging/cloning your 32bit Vista partition just in case something goes
wrong, so that you can easily restore it.
I formatted, named and assigned drive letters for all my partitions in
advance of installing the alternate OS's. All but the Win7 64bit adhered to
the drive letter assignments that I had preset. The 64bit OS reassigned the
drives, making its own partition C: (IPO Z

and lettering the other
partitions in sequence as it found them. Could have turned into a problem
but the change was restricted to only within the 64bit OS itself and the
others all kept using the original drive letter assignments.
