The invention discloses a multiple operation system switching method applicable to ARM (advanced risc machine) framework mobile equipment and belongs to the technical field of an operation system of mobile equipment. The multiple operation system switching method includes: initializing equipment for internal storage, internet equipment, a watchdog and I/O (input/output) firstly after the ARM framework mobile equipment boots, entering a selection interface of the operation system, setting corresponding booting parameters by a boot loader according to the operation system selected by a user, sending booting interrupt to a server end, searching a corresponding system kernel and file systems by a server after an interruption signal is truncated by the server, loading the system kernel to a client end in the form of files, burning into a set Flash partition before booting, mounting the file system under a root directory directly via an nfs (network file system) network protocol, and completing network booting of the operation system. By the aid of the multiple operation system switching method, preinstallation of the operation system on the ARM framework mobile terminal equipment is not required, and the purpose of realizing booting multiple operation systems via the network without local operation system is achieved.
