This is done using the diskutil and hdiutil commands in Terminal. Mac Terminal can also be used to create an installer from an ISO file. You can eject the drive once the process is complete. Hit Continue again and wait for the install disk to be created. The drive information will also be displayed below it.
When you hit Continue, you’ll be taken to a page where you can choose the ISO file. Once you have the ISO file, insert the drive, launch Boot Camp Assistant and choose the option to create an install disk.
