Thanks for your reply. I am using OS X 10.11 El Capitan. What I was referring to was when the computer is acting normally and I selected Win vs Mac OS X. What happened was when I was doing a reboot of Windows 7 following a series of updates, the computer hung up during a restart of Windows post updates when those updates were applying them selfs to Win but wouldn't. I ended up powering down, then back up pressing the option key to reinitialize the OS X volume vs Bootcamp(Windows).I was wondering if anyone else had experienced the same issue.
