This is actually from this question, but apparently you have to have a separate hardware array to run these two operating systems multi-seat. so i was wondering if you could have multiple computers connected some way and then use windows and Linux, perhaps selecting them at a sort of bios at the same time.
edit: e.g. you turn on a monitor connected to the main pc and can choose an operating system that you want to use, for example, ubuntu, and then a different person comes along and selects that they want to use windows?
