Problems solved by technology

The present invention further recognizes that while it is possible to back up the MBR to external storage, restoring the MBR requires locating the external storage and downloading information from the external storage, which takes time, and further depending on how often the user remembers to back up the MBR, the external storage copy may be obsolete

Embodiment Construction

[0015] Referring first to FIG. 1 , there is shown a high level block diagram of a data processing system embodying the present invention, generally designated 10 . System 10 in one non-limiting embodiment is a personal computer or laptop. System 10 includes processor 12, which may be, but is not limited to, a Lenovo PowerPC processor (or other processors commonly found in the industry manufactured by, for example, Intel or AMD). At power-up, processor 12 executes a bootloader program, such as a basic input / output system (BIOS) program 14, which may be stored in main computer memory 16, and loads data into secondary data storage 20, such as a hard drive or flash or other secondary storage A main operating system 18 (for example, Windows XP (registered trademark)) is loaded into the memory 16 . As shown in FIG. 1, the primary operating system 18 may reside in a partition of secondary data storage 20 labeled "Section C" immediately adjacent to the initial sector with a master bo...

Abstract

Any lacked subareas can be installed by using a service MER introduction service O.s. in a hidden and protected region, and by using an MBR replacing service MBR which is also backuped in the hidden and protected region in a condition that an MBR on a hard disk driver infected by viruses may stop the introduction.

Description

technical field [0001] The present invention relates generally to booting an operating system in a computer. Background technique [0002] When the computer is turned on, a boot loader, such as the Basic Input Output System (BIOS), stored in the computer's non-volatile solid-state memory is invoked, thereby beginning a "boot" process in which various initializations are performed. Foremost among these initialization tasks is the copying of the operating system from the computer's disk storage to typically the computer's volatile solid-state memory for the computer's processor to execute the operating system when the computer is in use. The operating system in memory is refreshed when the computer is turned off or when the computer is "rebooted." Speeds up computer operations by executing the operating system from relatively fast memory rather than from disk. [0003] A fundamental tool in booting is the Master Boot Record (MBR), which is usually accessed by the BIOS from s...
