A method for displaying a starting process of an electronic device is described hereinafter. Firstly, divide the starting process of the electronic device into a plurality of starting stages. Next, set a displaying data for each of the starting stages respectively. Lastly, transmit the corresponding displaying data to a displaying device and display the displaying data on the displaying device after executing each of the starting stages. Therefore, the method can make the starting process of the electronic device more intuitionistic. Furthermore, when the electronic device fails in the starting process thereof, the reason for the failure is easy to be preliminarily ascertained by viewing the displaying data displayed on the displaying device so as to provide a helpful reference to the trouble clearing.
