Free ISO Burner is done burning the ISO file when the status changes back to IDLE and you see Write ISO image done in the Progress box.
Once this happens, the disc will automatically eject from the drive.
Note: The time it takes to write the ISO image will depends mostly on the size of the ISO file and the speed of your optical drive, but the speed of your overall computer has an impact too.
Important: For help burning and using ISO files, please see the Tips section at the bottom of my How To Burn an ISO Image File to a Disc.
