I guess if we are going to bother with UEFI at all we should probably just
use Windows 8 64-bit, since that has much better support for UEFI,

64 bit o/s is required

Back to my original question, what is the correct procedure for copying over
a Windows 7 mirror disk image to a new machine? You copy the 100 MB system
partition and then the boot partition, on an MBR disk, and then mark the
system partition as Active?

Install using a 64 bit Win7 DVD if UEFI mode is your end objective.

If its an OEM image, its tied to the Bios of the original machine.
