The "golden rule" of dual-booting is to install the newest OS last. That
is, with WinXP already installed, add the second physical drive, then insert
the Vista DVD and run Setup.exe from inside WinXP, letting it either create
a new partition for itself or use one that you've already created with
WinXP's Disk Management. Setup will automatically create the dual-boot menu
in the process of installing Vista. Since it's too late for you to do that,
you'll need to either install Vista again from scratch, or use its Repair
function in Setup.exe. Or, use a third-party product, like EasyBCD.
From where you are now, your easiest course would be to physically install
both drives, with the Vista drive as the boot device. Then boot into Vista
and run EasyBCD from Neosmart Technologies. Have a look at this page:
