FYI on installing windows 7 on an iMac 2012 ~
After an extensive conversation with Tim, I had no issues creating a windows 7 image from winclone 7 using “wim” as preferred method for handling the cloning.
The issue we’ve had here is restoring - blank screen, windows 7 chime and then nothingness.
I finally solved this issue by restoring with winclone 6 and wim.
Not sure why, but we’ve used it now twice successfully.
