Yes. The slots are made much like you can partition a hard drive. That happens when an emmc image is installed. Slots are created when it's installed. Then other images are installed from within the settings menu. The emmc image is also know as recovery. Very similar to being able to install different operating systems on a partitioned hard drive. Once you boot to an image in the receiver you don't have to choose from a selection when you cold boot or restart the box. You'll see. Its all pretty easy.
