"Create a Windows 7 or later version install disk" does not show up as an option in Select Tasks
I have a MacBook Pro (15-inch, Late 2011) running El Capitan. I just installed a new hard drive and am trying to install Windows 7 using Boot Camp Assistant. On the Select Tasks window "Create a Windows 7 or later version install disk" does NOT show as an option. How do I create the install disk?
