I own a 2011 21,5" iMac, and I need to install Windows to run some software that is Windows only.
I have done this in the past by altering Bootcamp assistent so it can use bootable USB drives, which is not natively supported on the 2011 iMac. (as explained here)
Now lately I reinstalled my iMac, so I wanted to modify Boot Camp again. As it turns out Apple 'fixed' this workaround by making bootcamps internal files not editable anymore.
So after I realized I couldn't use a USB drive, I tried using a bootable DVD, this didn't work, since Boot Camp gave me the message that "There is no bootable USB drive installed". In other words, Boot camp thinks it needs a bootable usb drive, when those aren't supported on my model.
So my question; does anyone know a way to work around this 'fix'?
