Dear Steve, if the goal is:
Create a dual boot system on top of a pre installed Win7x64.

Why would the on-disk layout not tell you anything about how Win7x64 is currently installed an how it can be booted?
The system gets its operating system from the disk and obviously contains the only source of the bootable Win7x64 software.

You should not make any assumptions about which boot sequence will be used to boot the disk, because that is the real unknown here. (Assumptions are the mother of all f*ck-ups. :)
If you don't know and can't find out, just let the user decide / overwrite.
