I recently purchased an SSD and an optical drive HD caddy so I could use two HDs on my macbook pro. I installed the SSD in the normal HD slot in order to install Windows via optical drive. When I move my SSD over to the optical drive slot, Windows hangs on a black screen before the Windows logo and never boots. I tried moving the SSD back to the main HD slot but without the optical drive installed, the same symptoms occur - no boot. If I attached the optical drive again, windows boots without problem. This leads me to believe that Windows will not boot without the optical drive (which was present during installation). Has anyone experienced this and/or have a solution?
