From Manjaro
If this is your first time attempting to boot from an SD card or USB disk, you must enable multi-boot mode. Insert your Manjaro micro SD card or attach the Manjaro USB disk then hold down the button in the AV port by inserting a paper clip, a pin or something similar and keep it depressed while powering the device on. Keep the button pressed until you see the boot screen of your box. After a few seconds it should reboot off your SD card or USB disk. You are only required to do this once unless you reflash your eMMC.
