I also have this problem. I have a system using Windows 8.1 that I want to convert to Ubuntu.
No devices are listed in the "Installation Type" screen. I have tried the "nodmraid" option and still have the problem. Booting using CD trying to install Ubuntu 14.10. Using "Test Ubuntu" loads Ubuntu correctly.
