When you create the boot CD file, it is stored as an ISO image in the path you specified. You must be able to mount this image as a drive on the server on which you are performing a bare metal restore.
You can burn the boot CD ISO image onto compact disc (CD) or digital video disk (DVD) media accessible at system startup.
When you start the machine from the boot CD, the Universal Recovery Console launches automatically.
If performing a BMR on a virtual machine, this step is not required. Simply load the ISO image in a drive and edit settings for that VM to start from that drive.
