from mem i am shore you can dual boot either on your sd-card or ssd … i don’t know if core have a tutorial for it
but post on the official raspberry forum…
im shore there is a thread for it and how to do it…
here is a link…
https://www.raspberrypi.org/forums/
just use the search tool firstly
as for using the sd-card as a boot loader …i had suggested and wrote a thread about it in a fashion using the spi bus and a memory chip… if your a good coder you could code it using petitboot onto the sd-card… but you most likely need a custom kernel…or a rewritten one …
but have not had time to go into the idea of using the sd-card as a secondary boot-loader for the m2 drive…really u need a grub loader on the sd card… but i am not an expert coder…
some links…
i would say if he had a remote for it …it would only replicate the power button switch
put another idea through to add a cd/dvd and extra usb-3 hub to the bottom of the m-2 to core via there messenger online…dont know if argon will do anything though…if it makes their r&d…prolly in the works though…no doubt
