How to install Windows 8 on an early 2006 MacBook?
Windows 8 needs Boot Camp 5.1

Your Macbook can only run Boot Camp from DVD, not from USB [same for any Superdrive-euipped Macbook] &amp; also can, as far as I can tell, only run Boot Camp 4.
That means your only choices are Windows XP or Vista, 32-bit.
