Method of fast switching control for different operation systems operated in computer

Abstract

A method of fast switching control for different operation systems operated in computer is provided, including installing a first operating system, a second operating system and a second operating system kernel program in a hard disk of the computer. An event signal generation unit is connected to the computer. When the computer completes the booting process, the first operating system is loaded and executed, the second operating system kernel program memory region is established in a system memory, and the second operating system kernel program is loaded into the second operating system kernel program memory region. When the computer detects that a preset event signal is generated from the event signal generation unit, the second operation system kernel program preloaded in the second operating system kernel program memory region is executed, so that the computer is switched from executing the first operation system to executing the second operation system.
