I have a mid-2011 27" iMac with a 1TB drive that I have Windows installed on under Bootcamp. The Bootcamp partition w/ Windows is about 200GB of the 1TB. It occurs to be that I could install Win 7 on an External Drive and boot from than when I need Windows instead of usinf Bootcamp? What I would like to do is do a complete transfer of my current Windows setup to an External Drive (SO O can boot from external), then get rid of the Bootcamp partition so that the iMac HD is dedicated to teh Mac OS and files. Question - what is the best program that will allow me to copy my total Bootcamp partition w/ Win 7 onto an External Drive? Is this even possible?
