The invention relates to a novel LinuxBoot starting and guiding method and system based on an RISC-V server CPU. The method comprises the steps that firstly, ZSBL is executed, and loading and skipping to FSBL are carried out; then, the DTB, the OpenSBI and the LinuxBoot are loaded into a memory through the FSBL; the OpenSBI firstly executes bottom layer initialization, then executes early initialization of the platform, initialization of related hardware equipment and final initialization of the platform, and finally executes secondary boot to jump to a LinuxBoot kernel; a kernel of the LinuxBoot is loaded with the u-root to serve as initramfs, and the u-root serves as the initramfs; the LinuxBoot kernel loads a real Linux kernel image and a real device tree, and hardware configuration and parameters are set, so that the Linux kernel is started. According to the method, the system starting efficiency and flexibility are improved; rapid, reliable and flexible starting of the server system is realized. 本发明涉及一种基
