Trouble installing Boot Camp and Windows 8

I'm attempting to install Boot Camp for the first time using OS X 10.10.1 / Boot Camp 5.1.2. When I conduct the install, I get a message stating that this machine (Macbook Air, Late 2010) can only install Windows 7.

Apple's Documentation states the following:

The Windows ISO image or DVD must be of the 64-bit version of Windows 7 Home Premium, Windows 7 Professional, Windows 7 Ultimate, Windows 8, Windows 8 Pro, Windows 8.1, or Windows 8.1 Pro.

I did attempt to install W8, but was asked to provide W7 installation media. Based on the documentation I should be able to install Windows 8. Any thoughts or suggestions? Thanks
