so I have a MacBook Pro 17" with the newest Mountain Lion update and Bootcamp Windows 7. When I start the Mac, Mountain Lion shows me the forbidden sign, while still having this loading sign working but nothing happens and Windows shows me the bluescreen with the error code: "0x0000007B"
When I try to start the recovery in OS X the same happens (nothing...) and in Windows recovery the mouse and keyboard suddenly stop working so that I can't do anything. Additional to that I figured out that Windows has a problem with CLASSPNP.sys meaning that the problem lies in the hard drive. Now my question is since the mouse and keyboard stop working in Windows how can I reinstall the drivers in OS X?
