"No Bootable Device" after failed Boot Camp installation (Windows 8 - 1TB Fusion Drive)
I had a similar issue installing Windows 8 x64 on a 2013 Macbook Pro Retina running Mac OS 10.8.3 (which does support Windows 8) and the problem turned out to be an issue between the 32GB USB 3.0 installer drive I was using and Bootcamp Assistant/Mac OS. The USB drive was not defective.

I went through the Boot Camp Assistant process three times using a Microcenter branded 32GB USB 3.0 thumb-drive. When the system would reboot to start the Windows 8 installation process I would get a "No Bootable Device" error. After reading a suggesstion from another site I changed USB drives and used a Microcenter branded 16GB USB 2.0 thumb-drive and the Windows 8 installer USB was found and installation proceeded successfully.
