Abstract

The invention relates to the technical field of the switching of an operating system, and in particular to a method and a device for switching an operating system, which is used for classifying an independent storage area for each operating system in a terminal buffering area; storing an image file of the original operating system to the corresponding storage area when the original operating system is switched to a target operating system; acquiring an image file, stored in the corresponding storage area, of the target operating system; and starting the target operating system according to the image file of the target operating system. By utilizing the method and the device provided by the embodiment of the invention, when the system is switched, different processes of the current operating system are processed into the image file to be cached, and when the operating system is returned, the image file of the operating system can be directly acquired, and the operating system can be started. Thus, different operating systems can be rapidly switched and started.

Description

technical field

[0001] The invention relates to the technical field of operating system switching, in particular to a method and device for switching an operating system. Background technique

[0002] At present, mobile terminal applications are very common, and various operating systems that can run on mobile terminals are also increasing day by day. Generally, only one operating system is installed and used in a mobile terminal. When multiple operating systems are installed, the program corresponding to one operating system must be completely closed before the program corresponding to another operating system can be started. That is to say, the existing Technology does not enable simultaneous use of multiple operating systems.

[0003] In the prior art, there is also a technology of virtually dividing the central processing unit into two parts, and each part runs a different operating system. However, this way of running different operating systems through virtual divisi...
