What sometimes happens is that the driver for one OS leaves the hardware in a state the other OS does not know how to handle. I think it is probably because the driver only know how to handle the hardware in the power-on state, or the state the driver leaves it in. The reboot when changing from one OS to the other is not returning the hardware to the power-on state.
