The problem: I dual boot and have one OS set as a default but whenever I want to boot the other OS I have to select it during the timed event. Most of the time though I want to push the power button, walk away, and come back a minute or two later.
My crazy idea: A usb device, like a flash drive, with a boot loader and some sort of physical switch that toggles the default selection.
So now I ask, does anything like this exist? If not would it be possible to have a physical switch toggle a setting in the boot loader? And finally what are the less crazy solutions to this problem?
