Q.: Do I need to install the Boot Camp drivers first? What are the supported Boot Camp and Windows versions?
A.: Yes, the Boot Camp drivers shall be installed (but normally it's already done automatically by Apple installer, right after you install the Windows). The supported Boot Camp versions are 3.0 - 3.3, 4.0, 4.1, 5.0, 5.1, 6.0 and 6.1
