When I opened bootcamp the option to create a windows install disk was greyed out. I edited the plist to add my model identifier to the list of supported device. Returning to bootcamp I created a usb install disk and partitioned my HDD. My iMac restarted and loaded a windows style screen saying that no boot disks were found. I restarted in OS X and went to the startup disk preferences only to see that the install disk didn't show up. I then used Disk Utility to add a third partition to my Macs HDD to use as a setup disk as I read an article that on my iMac only the HDD and ODD can be used to install windows. Using CCC I cloned my install disk to the recently created partition. That didn't work either. My ODD isn't working so my only option is to use a USB. I seem to remember installing windows onto my 2008 Macbook from a USB. Why would apple have disabled this functionality?
