It is now possible to install Windows directly with an ISO since OSX El Capitan release : https://help.apple.com/bootcamp/assistant/6.0/#/bcmp173b3bf2. We no longer need to have a USB stick or a superdrive.
However, in my case (Macbook Pro early 2011 without superdrive), I can't see this proposition, I only have the old way.
I know it was possible to force the system to do a USB stick OSX installation by changing the plist.info. Can we do the same to enable this new functionality on old Macbook Pro ?
I try to install Windows 10.
