Hi all, I have the 2012 iMac (SSD) and have spent the best part of the morning trying to install Win 7 via Boot Camp but without luck. It seems the issue is I am using an external DVD superdrive and it is not possible to finish the install using the Win 7 DVD. Looked at other options (new disk image from the DVD - rename cdr to iso, boot camp assistant to create USB install - which hangs) but nothing working so far! Is there an easy guide to this somewhere please? Just want Win 7 via the DVD to install!
