Physical Button to Switch OS - - Help

I'm looking for a way to switch OS from Retropie to raspberrian with the press of a physical button. Then back to retropie with the same button

I currently have both OS's installed on berryboot.


-Full Story-
I'm building your run of the mill retropie arcade in a cabinet.
BUT I want to also have that cabinet function as a photobooth.
So, by default berryboot will load retropie. and the user can play games. OR at any point the user can press a physical button that stops retropie and boots raspberrian with will be overridden to actually just load the photobooth and with button(s) the user can take 3 pictures that will automatically print on HP Sprocket printer. (there are a ton of tutorials on this)
Then, when picture time is done the same button switches the user back to retropie

Is this possible? How?

What is this "raspberrian" you write of?

Maybe a lot easier to have two RPis and a KVM switch.

Not only would using two Pis provide redundancy, but the switchover could be made to be almost instant, versus waiting for the other OS to come up.....
