Operating system construction method and device, operating system starting method and device, electronic equipment and storage medium

The embodiment of the invention provides an operating system construction method and device, an operating system starting method and device, electronic equipment and a storage medium. The operating system construction method comprises the following steps: constructing a kernel of an operating system in a development framework of the operating system, wherein the kernel at least comprises an initialization component; configuring a startup configuration file of a kernel of the operating system for the initialization component, wherein the startup configuration file is used for loading a self-defined user mode component when the kernel of the operating system is started; and compiling a kernel of the operating system into an executable file of the operating system. In the scheme of the embodiment of the invention, the loading of the user-defined user mode component can be realized in the compiled executable file of the operating system, and the user-defined user mode component is flexibly configured, so that the
