OS processing method, system and non-transitory computer readable storage medium thereof

An OS processing system disposed on a host computer, wherein the OS processing system comprised:

• a storage unit comprising an MBR, wherein the storage unit stores a boot priority order of the host computer;
• a boot reading device for reading a boot loader according to the boot priority order of the host computer when the host computer is booting, wherein the boot loader comprises a preset version signature;
• and
• a processing unit communicated with the storage unit and the boot reading device, wherein the processing unit comprises:
• a boot module for executing a signature detecting program comprised in the boot loader to detect data stored in a specified address of the MBR of the storage unit, wherein the data stored in the specified address corresponds to a present version signature of a present OS of the host computer;
• a determining module for reading an OS image from the boot reading device when it is determined that the present version signature of the host computer does not match the preset version signature according to the data stored in the specified address, and installing an OS on the host computer according to the OS image, and taking the installed OS as the present OS of the host computer;
• and
• a signature amending module for amending the data stored in the specified address of the MBR according to an image version signature of the installed OS for corresponding to the present version signature of the present OS of the host computer.

A non-transitory computer readable storage medium with a computer program to execute an OS processing method for a host computer, wherein the host computer comprises an MBR, the OS processing method comprises:

• (a) when the host computer is booting, reading a boot loader from a boot reading device according to a boot priority order of the host computer, wherein the boot loader comprises a preset version signature;
• (b) executing a signature detecting program comprised in the boot loader to detect data stored in a specified address of the MBR of the host computer, wherein the data stored in the specified address corresponds to a present version signature of a present OS of the host computer;
• (c) when it is determined that the present version signature of the host computer does not match the preset version signature according to the data stored in the specified address, reading an OS image from the boot reading device of the host computer, installing an OS on the host computer according to the OS image, and taking the installed OS as the present OS of the host computer;
• and
• (d) amending the data stored in the specified address of the MBR according to an image version signature of the installed OS for corresponding to the present version signature of the present OS of the host computer.
