Hey all, I'm aware you are able to install Windows via a usb stick through bootcamp, however my question is whether you are able to install it from a USB external hard drive. I've loaded up a Windows 8 .iso on to my WD My Passport and tried to get it going through bootcamp, but every time I try I get "Your bootable USB drive could not be created." I have made sure the image is not mounted. Any ideas? Does it just not work on an external HD and have to be a flash drive? Thanks.
