Yep, you won't be able to launch setup in either XP or Vista 32 bit, so you
will have to boot from the Vista x64 DVD and select the third drive on which
you would like to install the OS. Vista x64 will show up on the Vista Boot
manager, and XP will still be available under the legacy boot manager
'Earlier version of Windows'.
You might need to rename the Vista x64 entry since you won't be able to
easily tell which is 32 or 64 bit, for this you use EasyBCD by NeoSmart
Technologies
