Claim:
1. An electronic device with a plurality of booting modes at least including a first booting mode and a second booting mode, comprising: at least a button unit, wherein the button unit outputs a first signal according to a trigger event for choosing one of the first booting mode and the second booting mode; a control module, including a buffer unit, wherein the control module is connected to the button unit, wherein the control module determines the booting mode represented by the first signal, and sets the buffer unit according to the first signal by storing a status signal corresponding to the determined booting mode in the buffer unit, and the control module outputs the status signal, and then the first signal after a delay time; a south bridge, connected to the control module and the south bridge receiving the status signal corresponding to the determined booting mode; a super input/output (I/O) unit, connected to the control module and the south bridge, wherein the super I/O unit receives the first signal outputted from the control module and transmits the first signal to the south bridge; and a basic input/output system (BIOS), connected to the south bridge; wherein the south bridge restarts the electronic device when receiving the first signal from the super I/O unit, and after the electronic device is restarted, the BIOS reads the status signal stored in the buffer unit and controls the south bridge to execute a corresponding booting procedure corresponding to the determined booting mode according to the status signal.
