Q: Retina iMac 3tb Fusion drive Boot Camp failure

Trying to install Windows 8.1 to a 1tb Bootcamp partition on 3tb Fusion drive. BCA creates the partition, Windows installer sees it, but requires formatting it, but then it can't install to it. I get an error that it can't create or see the partition. I'm assuming this has to do with BCA creating the partition someplace Windows can't handle it (past the first 2.2tb of the drive).

Here is the info requested in a previous thread.
