To my knowledge, Windows (XP, at least; probably others) labels the boot
filesystem on install, and just probes all disks every boot for a
filesystem with the given label. This is why you can move a Windows disk
around with relative impunity (as long as the controller drivers are
installed); but simply copying all those files to another filesystem
(a-la dump/restore on BSD) never results in a bootable OS, even if you
put them back in the same place.

This is also why booting with two attached clones of the same Windows
system disk is so fun.
