The invention discloses a method for device start controlling and an electronic device. The method is applied to an electronic device which includes a basic input and output system. A first operation system can be installed in the electronic device. The method includes the following steps: after the electronic device is powered on and an initialization process of the basic input and output system is completed, through a network start module, a first sequence data packet is obtained from a server connected with the electronic device; based on a first preset sequence in the first sequence data packet, a first installation program corresponding to a first operation system is searched for at M positions sequentially, wherein M is an integer larger than or equal to 1; and when the first installation program is obtained from an ith position in the M positions, the first installation program is executed so as to install the first operation system in the electronic device, wherein i is any integer smaller than or equal to M.
