I have a 2014 Mac Mini that is running a 1.4 Ghz Dual Core I5. When I establish Boot Camp on it, the drive builds a copy of Windows onto it, but after completion of the operation, the Mac doesn't startup into the partitioned second operating system. Any ideas as to how I might get it to do so, or am I using a logic board on the Mini that doesn't allow for dual boot thus need a replacement?
