Its much easier to open the ISO and copy the contents of each disk to 3 separate USB drives OR 3 separate SD cards and a card reader. You might have to plug and unplug the readers when it asks for the next disk, or card. Just swapping the cards doesn't work. You need to reboot the reader so to speak.
