The invention discloses a multi-operating-system switching operation method, computing equipment and a storage medium. The multi-operating-system switching operation method comprises the following steps: modifying a kernel loading address into a second storage address of a second kernel of a second operating system in an internal memory; loading a second kernel of a second operating system according to the kernel loading address; and obtaining a second system snapshot of the second operating system from the external memory, and running the second operating system according to the second kernel and the second system snapshot. According to the method, the operation system is switched and run by modifying the kernel loading address, and the system snapshot is acquired from the external memory, so that when the kernel loading operation system is acquired, the operation system is restored to the state of pausing or ending running last time; in order to realize rapid switching of the operating system, the virtual machine does not need to be constructed to install another operating system, so that the switching efficiency of the operating system and the operating efficiency of each operating system are improved.
Description
technical field [0001] The present invention relates to the field of operating systems, in particular to a multi-operating system switching operation method, a computing device and a storage medium. Background technique [0002] With the development of computer technology, when people use computers, they may need to use multiple different operating systems at the same time to process some more complex tasks. Therefore, when using a computer, it is necessary to be able to switch the operating system currently running in the computer. When there are multiple operating systems installed in the computer and you want to switch from the currently running operating system to another running operating system, you need to exit the currently running operating system, enter the BIOS interface, and select another operating system to start. But this was very time-consuming at the time, with each switch taking minutes or more. [0003] In the prior art, in order to quickly switch the ru...
