Dual Booting on a tablet/notebook hybrid, just curious

[Incblob]

My question is this:

Using the example of the Asus transformer t100. Say you installed Linux on top of the base windows OS.

when dual booting you are given a choice between the OSs, you have to press enter to select.

This should work when you have the keyboard accessory attached.

But in "tablet mode", since as far as i can tell touch capabilities are loaded with the OS ,  you won't have an Enter to press, so how would you select which OS to boot?

Has anyone tried this or knows how this would go?

Just curious...

 

While we're at it, does anyone know how well dual booting on chromebooks works?

 

ps: yes, there is a timer and one of the OSs would boot after a couple of seconds, i was just wondering if you could make any kind of input using the touchscreen at the OS select screen.
