System starting method, device and system and storage medium

The embodiment of the invention provides a system starting method, equipment, a system and a storage medium. In the embodiment of the invention, the starting process of the operating system is divided into a plurality of starting stages, and for at least part of the starting stages, routines in the starting stages are divided into a plurality of groups; when the operating system is started, performing initialization operation on each starting stage in sequence; when initialization operation is carried out on at least part of the starting stages, concurrent scheduling is carried out on routines in a plurality of groups by taking the groups as units, so that the starting time of the operating system can be shortened, and the starting efficiency of the operating system is improved. 本申请实施例提供一种系统启动方法、设备、系统及存储介质。在本申请实施例中，将操作系统的启动过程划分为多个启动阶段，针对至少部分启动阶段，将启动阶段中的例程划分到多个分组；在启动操作系统时，按序对每个启动阶段进行初始化操作；在对至少部分启动阶段进行初始化操作时，以分组为单位对多个分组中的例程进行并发调度，这样可缩短操作系统的启动时间，提高操作系统的启动效率。
