An electronic device with a plurality of booting modes comprises at least a button unit, a control module, a control chip unit, a super I/O unit and a Basic Input/Output System (BIOS). One of the button units outputs a first signal according to a trigger event. The control module includes a buffer unit connected to the button units. The control module sets the buffer unit according to the first signal. The control module outputs a status signal and copies the first signal and outputs the first signal after a delay time. The control chip unit receives the status signal. The super I/O unit receives the first signal outputted from the control module and transmits the first signal to the control chip unit. When the control chip unit receives the status signal and the first signal, the BIOS executes the corresponding booting procedure according to the status signal.
