Manjaro not booting

[pfeerick]

There is a 'known issue' with the Manjaro ARM images in that the splash screen will show forever, and you need to hit ESC to get the installer screen to come up. Unfortunately, there is then a second issue... if you press ESC a couple of times, it will probably clear the splash screen, AND cancel the installer. That would explain the 'installed canceled' message, and also the seemingly excessive boot time. You should be able the hit esc as soon as you seen the slash screen, and IIRC, should see the boot messages and then the installer as soon as it's ready.
