Embodiment Construction

[0020] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0021] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a method for switching the operating system, such as figure 1 As shown, the method includes:

[0022] Step 101, dividing an independent storage area for each operating system in the terminal cache area;

[0023] Step 102, when the original operating system is switched to the target operating system, the image file of the original operating system is saved to the corresponding storage area;

[0024] Step 103, obtaining the image file stored in the corresponding storage area by the target operating system;

[0025] Step 104, start the target operating system according to the image file of the target operating...

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...
