The following describes the control method for operating system boot provided in this embodiment in detail with reference to the drawings. The control method for starting the operating system described in this embodiment is applied to a computer capable of running various types of operating systems, for example, a Linux operating system, an XP operating system, a VISTA operating system, a WIN7 operating system, a WIN8 operating system, a WIN8.1 operating system, a WIN10 operating system, and the like.

For another example, these modules may be integrated together and implemented in the form of a system-on-a-chip (SOC).
The present embodiments may be described using the expression "coupled" and "connected" along with their derivatives. For example, some embodiments may be described using the term "coupled" to indicate that two or more elements are in direct physical or electrical contact.
