I have the same problem trying to install Windows 7 on iMac 10,1 (late 2009) running OS X 10.11.5 whose optical drive is not working.
The "Install or remove Windows 7" option is greyed out in the Select Tasks screen of boot camp assistant.
Here are my outputs:
akays-iMac:Contents akay$ diskutil list
