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

摘要

An operating system (OS) processing method for a host computer includes the following steps: when the host computer is booting, a boot loader is read from a boot reading device according to a boot priority order of the host computer. A signature detecting program included in the boot loader is executed to detect data stored in a specified address of a master boot record (MBR) of the host computer. 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, an OS image is read from the boot reading device, an OS is installed on the host computer according to the OS image. The data stored in the specified address of the MBR is amended according to an image version signature of the installed OS.

1. An operating system (OS) processing method for a host computer, wherein the host computer comprises a master boot record (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.
