Abstract
A computer multi-OS switching method, in which a data exchange region for storing OS running environment information is provided, wherein the method includes: A. saving running information of computer hardware devices in a random access memory (RAM) by the computer after receiving a command for switching OS; B. obtaining OS running environment information of OS to be switched to from the data exchange region and storing the obtained OS running environment information in the RAM by the computer; C. restoring running state of the computer hardware devices based on its running information stored in the RAM, obtaining a preset OS to be switched to, starting the OS and subsequently executing the OS running environment information in the RAM by the computer. The method reduces the time for switching between multi-OSs in a computer.
