An electronic equipment is provided, which includes a plurality of boot devices and a basic input/output system (BIOS). The BIOS is electrically coupled to the boot devices and used for recording driving parameters of the boot devices and a driving sequence of the driving parameters. The BIOS drives the boot devices by using the driving parameters according to the driving sequence, so as to perform a system booting operation of the electronic equipment. When any one of the boot devices accomplishes the system booting operation, the BIOS adjusts a driving parameter corresponding to the boot device as a first order of the driving sequence, so that the boot device becomes a first selected system booting device. Furthermore, a boot method for an electronic equipment and a storage medium thereof are provided.
