How to install Bootcamp on 3TB Fusion Drive

[iMore Question]

I have a Mid 2015 27" iMac With Retina display. 3.3 Ghz Core i5, 8 GB Ram with 3TB Fusion Drive. I am trying to install Bootcamp and install Windows 8.1 but bootcamp assistant always gives the error "cannot install windows to this volume". After doing some reading, it seems that windows must be installed within the first 2.2 gb and on the second partition which bootcamp cannot seem to do. Has anyone gotten this to work? Is it possible?

Thank you for your help.

Do you have an AppleStore near you? I'd take this up with the GeniuBar...
