Hi, Erik.
You know, of course, that Disk Management lets us change all the drive
letters except the System and Boot volumes. There is (normally) only one
System Partition for the whole computer, but each operating system has its
own Boot Volume. Typically, one OS shares its boot volume with the System
Partition.
By setting Drive 1 as your boot device before running Vista Setup, you
forced Setup to write its startup files onto Drive 1 in a single-boot
configuration. If you had left Drive 0 as your boot device when installing
Vista, it would have updated the startup files there to allow you to
dual-boot without resetting the boot device in your BIOS each time.
Microsoft's dual-boot system works like a "Y" (or a tree, if there are more
than two branches). The boot process always starts in the System Partition,
then branches to wherever the \Windows folder is for the OS we choose. But
you've created two "Y" systems, each on a different hard drive, so you have
to change the BIOS to choose between them before the boot process even
starts. It's OK, if that's what you want, but since you said it's "kind of
a pain", you might want to change the startup files on one (or both) of your
HDs to create the dual-boot startup menu.
