The boot drive must always be the first Primary partition of the 
first drive, and that drive is C. A and B are reserved for floppy 
type drives at POST, although B can be whatever you wish it to be, 
once you get into Windows but not during POST.

However, the operating system can be on any partition you wish, and 
that is what you have described here. A windows Boot drive has very 
few files actually visible on it, but is designated within the Master 
Boot Record of the drive as the boot drive. The boot drive will point 
to the location of the operating system.

So, the boot drive is always on C, BUT the operating system can 
reside wherever you want.
