The present invention relates to a method for repairing an operating system using an external storage medium, and in particular, when a problem occurs in an operating system installed in a computer, the operating system repair method that heals problems caused by the operating system without reinstalling the operating system or applications installed on the computer It is about.

In general, Microsoft's Windows-based operating systems (WINDOWS 98, WINDOWS 98 SE, WINDOWS ME, WINDOWS 2000, WINDOWS XP, WINDOWS 2003, and WINDOWS VISTA) use recovery console commands to help solve operating system problems. . The recovery console command refers to a command in which a user of the computer replaces a file of a damaged operating system with a normal file by using a console mode command after the computer is booted in console mode. For example, if the monitor displays the message "Failed to load logon user DLL.msgina.dll. Please contact your system administrator to replace or restore this dll". This can be done by running the console commands listed in Table 1 below.

expand msgina.dl _ c: \ windows \ system32 \ msgina.dll

The console command in Table 1 inserts the original installation CD into the computer and reads the file to replace the damaged file from the original CD and installs it to the computer. However, it is well known that the majority of users who use a computer do not use the recovery console as shown in Table 1 to solve the operating system problem. If the operating system fails, the user cannot log on to the operating system. Many will not be able to take appropriate action. Furthermore, in the event of a serious problem with the operating system, a message such as "Failed to load logon user DLL.msgina.dll. Please contact your system administrator to replace or restore this dll" will not appear on the monitor. screen) often appears. In this case, most users will format the operating system with the problem and reinstall Windows or call an AS specialist for resolution. However, AS specialists do not know how to deal with many problems with the Windows operating system, and the resolution of operating system problems will depend entirely on the skill of the AS technician. As a result, many users are suffering from losing their data or reinstalling all existing applications in the process of reinstalling the operating system.

Accordingly, the present inventors propose a method and a medium that can easily solve the problem by accessing the operating system through an external storage medium and reloading only the files necessary for repairing the operating system to a computer when a problem occurs in the operating system.

As described above, an object of the present invention is to solve the problem by accessing the operating system through an external storage medium and reloading only the files necessary for repairing the operating system to a computer when a problem occurs in the operating system. In providing.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a conceptual diagram of an embodiment of the present invention.

The present invention is a CD-ROM, CD-RW, DVD-R, DVD-R (Dual Layer), DVD-RW, DVD + R, DVD + RW, DVD-RAM, blue-ray disc, floppy Boots the computer 200 to console mode via an external storage medium 100 such as a disc, USB storage device, and HD-DVD (High Density Digital Versatile Disc). (Or service files, and other application programs provided by the operating system, hereinafter omitted) by replacing the system file 110 provided in the external storage medium 100 with the user of the computer 200 to reinstall the pre-installed operating system You can use it without having to.

To this end, the external storage medium 100 includes a system file 110, a system file list 120, a boot image 130, and a manager program 140. The boot image 130 includes a system file that enables the computer 200 to boot in the console mode. As an example, if the boot image is DR-DOS or MS-DOS, the boot image 130 has system files such as IO.SYS, COMMAND.COM, MSDOS.SYS (if MSDOS), and corresponding system files. Is located in a bootable area on an external storage medium (eg CD). As such, in order to boot and control the computer through the external storage medium 100, the boot priority of the computer 200 should be set to the external storage medium 100. This will be briefly described with reference to FIGS. 2 and 3.

2 and 3 illustrate a process of determining boot priorities among the accessible BIOS setup (or CMOS setup) screens after the computer is powered on. This BIOS setup can be entered by booting the computer and pressing Del, F1, F2, or ESC. The keys that must be pressed for BIOS setup vary with each BIOS manufacturer (eg, AMI, Phonix) and are usually described in detail in the manual provided by the vendor selling the motherboard.

First, FIG. 2 illustrates sub-menus displayed when the power menu is entered in the BIOS setup menu. As shown, the power menu includes a menu related to boot priority determination menu 10, boot setting configuration, and security. When the boot priority determination menu 10 is selected, The submenu shown in FIG. 3 is displayed. In the sub-menu illustrated in FIG. 3, booting priorities of devices mounted in the computer 200 may be set. In the drawing, a floppy disk, a hard disk (PM-ST32122A, model name of the Seagate hard disk drive), a CD-ROM drive (20, SS-Pioneer CD-ROM, Pioneer Japan CD-ROM), and a network boot device (YUkon PXE) Is indicated. Here, the BIOS should be set such that the first boot device is the CD-ROM drive 20.

When the boot priority is set in the CD-ROM drive by the BIOS setup, an external storage medium (in the present invention, the external storage medium is mainly described as CD-ROM in the present invention). Hereinafter, reference numeral 100 denotes an external storage medium. In particular, the CD-RW, DVD-R, DVD-R (Dual Layer), DVD-RW, DVD + R, DVD +, in addition to the CD-ROM, may be provided. Of course, RW, DVD-RAM, Blu-ray Disc, floppy disk, USB storage, and HD-DVD (High Density Digital Versatile Disc) in Sony's PlayStation can be used.) Insert and boot. After the CD-ROM 100 is inserted into the computer 200, the boot image 130 provided on the CD-ROM 100 is loaded into the RAM 220, and the RAM 220 provides the boot image to the processor 230. 130 is executed. The processor 230 interprets and drives the boot image 130, and provides the manager program 140 with control of the operating system. The boot image 130 is most commonly used free DR-DOS, but the boot image of another operating system that can be controlled in the console mode by obtaining a separate license may be used. When the computer 200 is booted by the boot image 130, the manager program 140 may auto-run and perform the functions described below.

1) Access the hard disk drive 240 to check the type of operating system, and the service pack version pre-installed on the hard disk drive 240.

2) The file system of the hard disk drive 240 is determined by accessing the MBR (Master Boot Record) of the hard disk drive 240.

3) an interface menu for allowing a repairman of the repair target computer 200 to manually load system files to the computer 200 manually on a monitor (not shown), and corresponds to an item selected from the displayed interface menu. The system file 110 is loaded into the hard disk drive 240 by referring to the file system list.

Here, the determination of the file system described in 2) may be obtained by accessing the MBR of the hard disk drive 240, but may be obtained as described below.

First, the manager program 140 installed in the external storage medium 100 checks the existence of an operating system based on a File Allocation Table (FAT) file system. Next, if the operating system is not determined based on the FAT, the manager program 140 checks the existence of the operating system based on the NTFS. In this case, the method of checking the type and version of the OS pre-installed in the hard disk drive 240 may be understood by referring to the OS license file pre-installed in the hard disk drive 240. Of course, in addition to the license file, the type of operating system can be grasped through a log file recorded on the hard disk drive 240 when the operating system is installed and updated. Hereinafter, a file recorded on the hard disk drive 240 and capable of grasping the type of operating system is referred to as an "information file". Figure 4 shows an example of an information file that can determine the type of operating system and whether the service pack is applied. Typically, when an operating system is installed on the computer 200, a software end user license agreement is copied to a system folder (such as system32) of the operating system (such as windows xp). The depicted information is intended to convey the contents of the contract between the user and Microsoft, but, as illustrated, includes information about the operating system installed by the user. In the drawing, "XPSP_2 ..... RTL_KO" is shown, which indicates that Windows XP Service Pack (S2P) 2 has been applied, a retail (RTL) product, and Korean version (_KO). These information files can be placed in different paths for different operating systems (eg windows 98, windows 98 se, windows me, windows xp home, windows xp pro, windows 2000 pro, windows 2000 server, windows 2003, and windows vista). In addition, the manager program 140 may have such path information.

When the manager program 140 determines the type of OS, service pack version, and file system pre-installed on the repair target computer 200, the manager program 140 may repair the repair target computer 200 as described below. Can be.

4) The system file corresponding to the repair target computer 200 is loaded into the hard disk drive 240 by referring to the type of OS and whether the service pack is applied.

5) The person repairing the repair target computer 200 sees the state of the computer 200 and manually loads a system file into the hard disk drive 240. At this time, the hard disk drive 240 is loaded with only the minimum system files necessary to repair the operating system of the computer 200.

When the system file is loaded into the hard disk drive 240 as described above, when the method of 5) is applied, the time required to repair the operating system pre-installed on the hard disk drive 240 can be greatly shortened.

Meanwhile, in the present invention, the system file stored in the external storage medium 100 is replaced by the system file of the operating system installed in the hard disk drive 240, but may be processed according to the following description.

If the external storage medium is a medium read from CD-ROM, DVD-ROM, and other optical drives, the computer 200 requires two optical disk drives (such as a CD-ROM drive), one with the operating system source disk. The external storage medium 100 is inserted into the other. In this case, the boot right should be assigned to the optical drive into which the external storage medium 100 is inserted. Accordingly, the manager program 140 provided in the external storage medium 100 may determine the type of OS installed in the hard disk drive 240 and the file system, and then load the system file to be loaded into the hard disk drive 240. May be extracted from the original disk, extracted, and loaded into the hard disk drive 240. Normally, the system disk is compressed into a cabinet file on the original disk, and is decompressed through a separate decompression program provided on the original disk. Therefore, the manager program 140 must include a decompression program that can decompress files included in the original disk. In addition, the manager program 140 should have a function of loading a system file extracted and decompressed from the original disk into a directory set according to the type of operating system installed in the hard disk drive 240. On the other hand, if the external storage medium 100 is not a medium read from the optical drive (eg USB storage medium), the computer 200 requires one optical drive, the original disk is inserted into the optical drive, The external storage medium may be connected to the computer 200 and boot up. In addition, the manager program 140 may replace a system file of an operating system installed in the hard disk drive 240 by calling a system file from an operating system backup folder previously installed in the hard disk drive 240 in addition to the original disk. Here, the operating system repair method using the external storage medium 100 and the original disk can be applied to other embodiments to be described later, but a duplicate description of the embodiment in which the original disk is added to the same process is performed. The description thereof will be omitted.

5 shows an example of an interface prepared by the present applicant for the manual operation of the repair target computer 200.

The illustrated interface has an automatic repair menu as described in the "M" item, including Master Boot Record repair, NTLDR (NT LOaDeR) repair, MSGINA error repair.

If the repair target computer 200 indicates an error during booting, an error message is output to the monitor or the down symptom is displayed, and a person repairing the repair target computer 200 may proceed with manual repair by referring to each item described below. .

6) If the message "Ntldr is missing" is displayed on the monitor, the system file related to the NT loader is damaged among the operating system files. Select item 3 of FIG. 5 to take action. When the repairee repairs the computer 200 selects item 3 shown in FIG. 5, the manager program 140 may convert the NTldr file among the system files 110 stored in the CD-ROM 100 to the hard disk drive 240. Will be loaded. At this time, the manager program 140 refers to the type of operating system pre-installed on the hard disk drive 240, the service pack version, and the file system, and the NTldr file corresponding to the pre-installed operating system on the hard disk drive 240 is stored in the hard disk drive. Will be loaded. If one or more system files need to be loaded into the hard disk drive 240, the manager program 140 may refer to the system file list 120 to determine among the plurality of system files 110 provided in the CD-ROM 100. The system file is loaded into the hard disk drive 240. In general, a Windows-based operating system often corresponds to a plurality of system files for one system function.

7) When the message "Non-system disk or disk error, Replace and press any key when ready" is displayed on the monitor (not shown), it is a Boot strap provided in the master boot record (MBR) of the hard disk drive 240. If the code is damaged or the strap code of the boot record is damaged, it can be corrected by selecting item 1 of FIG. 5.

8) Ntoskrnl.exe is displayed on the monitor (not shown), such as "Windows cannot start because the following file is missing or corrupt: <windows root> \ system32 \ ntoskrnl.exe please reinstall a copy of the above file." If the file is damaged, select item 6 in FIG. 5 to take action.

In addition to 6) to 8) described above, FIG. 5 further includes a plurality of menus in which the computer to be repaired responds to a message and a symptom indicating a monitor, and a menu for various types of malfunctions in which a message is not output (J menu: FIX UNKNOWN ERRORS), and a menu of failure symptoms that are re-booted without a message output (K menu: FIX REBOOT ERRORS). The menu for repairing collectively (M menu: AUTOFIX WINDOWS ERRORS) is presented. These menus are used to collectively replace the system files installed in the computer 200 with the system files commonly required to heal the corresponding symptom of the operating system's system files (e.g., to be rebooted without a message output). .

In the case of a Windows-based operating system, system files are normally distributed in C: Windows and C: Windows \ system32, but very few system files are also distributed in the root of the hard disk drive 240.

6 shows system files provided at the root of the hard disk drive 240.

As shown in the figure, a recycler, program files, and windows folders are provided at the root of the hard disk drive 240, and system files such as ntldr files and NTDETECT files are located.

If the NTDETECT file is damaged, there is a symptom of repeating the re-boot while the repair target computer 200 is in the process of booting, and the person repairing the repair target computer 200 refers to the symptom shown in FIG. 5. You can choose to take action. Here, the system file may be provided in various paths in addition to the Windows directory (c: \ windows, c: \ windows \ system32, etc.), and the CD-ROM 100 may be included in either the manager program 140 or the system file list 120. The system files 110 included in the s) should be provided with information, ie, path information, in which directory among the directories provided in the hard disk drive 240.

7 shows a schematic flowchart of an embodiment of the invention.

First, after repairing the computer 200 to be repaired, the computer 200 is powered on and then enters the BIOS setup to give the CD-ROM 100 boot priority. In this case, as an external storage medium bootable in place of the operating system pre-installed in the computer 200, in addition to the CD-ROM 100, CD-RW, DVD-R, DVD-R (Dual Layer), DVD-RW, DVD + R, DVD It can be one of + RW, DVD-RAM, Blu-ray Disc, floppy disk, USB storage device, and HD-DVD (High Density Digital Versatile Disc).

Of course, in addition to the external storage media mentioned here, anything that can be booted in connection with a computer can be used. Next, the person who repairs the computer 200 boots the computer 200 using the CD-ROM 100 (S301). When the computer 200 is booted by the CD-ROM 100, control of the computer 200 is transferred to the manager program 140. Next, the manager program 140 provided in the CD-ROM 100 is automatically executed together with the booting of the computer 200, and the FAT file system is loaded into a memory (not shown) provided in the computer 200, and then the hard disk is loaded. The drive 240 is accessed (S302). Next, the manager program 140 determines whether the operating system installed in the hard disk drive 240 is windows me. Here, the manager program 140 may determine the type of OS and the service pack application version by one of the methods described below.

9) A method of determining a Windows based operating system based on a FAT file system (eg, a FAT32 file system), and a method of determining an operating system based on an NTFS file system if a windows based operating system of a FAT file system is not found.

10) After the step of booting to the external storage medium (100) (S301), a method of determining the file system by accessing the master boot record (MBR) of the hard disk drive 240. In this case, steps S302, S322, and S323 shown in the drawing are unnecessary.

Hereinafter, the present embodiment will be described based on the method of 9). After the step S302, the manager program 140 determines whether the operating system is windows me in a state where the file system is FAT (the FAT file system is loaded in the memory) (S303). In this case, the manager program 140 may check whether the operating system exists by searching for whether an information file exists in a specific directory (for example, C: \ WINDOS \ SYSTEM32) of the operating system installed in the hard disk drive 240. Next, when it is determined that the operating system installed in the hard disk drive 240 is windows me, the manager program 140 looks up the system file list 120 and selects a system file corresponding to windows me (S304). The system file 110 provided in the 100 is loaded into the hard disk drive 240 (S305). At this time, the system file 110 loaded into the hard disk drive 240 is loaded into the corresponding installation path as described in the system file list 120. For example, the manager program 140 provides an installation path from the system file list 120 for whether the system file 110 to be loaded to the hard disk drive 240 is a C: \ WINDOWS directory or a C: \ WINDOWS \ system32. The system file 110 provided in the CD-ROM 100 is loaded according to the corresponding path. Next, as a result of the determination of the manager program 140, when the operating system is windows 98 (S306), the manager program 140 selects a system file list corresponding to windows 98 (S307), and selects the selected system file list 120. The system file 110 is loaded into the hard disk drive 240 (S305). Next, as a result of the determination of the manager program, when the operating system is Windows 98 SE (S308), the manager program 140 selects a system file list corresponding to WINDOWS 98 SE (S309), and the system file according to the selected system file list. 110 is loaded into the hard disk drive 240 (S305). Next, as a result of the determination of the manager program, when the operating system is WINDOWS 2000 PRO (S310), the manager program 140 selects a system file list corresponding to WINDOWS 2000 PRO (S311), and the system file according to the selected system file list. 110 is loaded into the hard disk drive 240 (S305). Next, as a result of the determination of the manager program, when the operating system is WINDOWS 2000 SERVER (S312), the manager program 140 selects a list of system files corresponding to WINDOWS 2000 SERVER (S313), and the system files according to the selected system file list. 110 is loaded into the hard disk drive 240 (S305). Next, as a result of the determination of the manager program, when the operating system is WINDOWS XP Home (S314), the manager program 140 selects a list of system files corresponding to WINDOWS XP Home (S315), and the system files according to the selected system file list. 110 is loaded into the hard disk drive 240 (S305). Next, as a result of the determination of the manager program, when the operating system is WINDOWS XP PRO (S316), the manager program 140 selects a list of system files corresponding to WINDOWS XP PRO (S317), and the system files according to the selected system file list. 110 is loaded into the hard disk drive 240 (S305). Next, when the manager program determines that the operating system is WINDOWS 2003 (S318), the manager program 140 selects a system file list corresponding to WINDOWS 2003 (S319), and the system file 110 according to the selected system file list. ) Is loaded into the hard disk drive 240 (S305). Next, when the manager program determines that the operating system is WINDOWS vista (S320), the manager program 140 selects a system file list corresponding to WINDOWS vista (S321), and the system file 110 according to the selected system file list. ) Is loaded into the hard disk drive 240 (S305). Here, the system file list of each operating system (for example, WINDOWS ME to WINDOWS 2003) is loaded into the hard disk drive 240 by the step (S304, S307, S309, S311, S313, S315, S317, S319, and S321). System files are selected by referring to the service pack version of each operating system. This means that different system files are installed on the same type of operating system depending on the service pack version. For example, even if the operating system already installed on the hard disk drive 240 is WINDOWS XP PRO, in the case of the Ntoskrnl.exe file provided in C: \ WINDOWS \ system32, the original version file of WINDOWS XP PRO, the file applied with Service Pack 1, and the service Files with Pack 2 are not the same file. Although the same name and similar function, the file is partially modified as the service pack version is increased. If this is not taken into consideration, the system file loaded into the hard disk drive 240 may not operate normally. Table 2 below shows the service pack version of each operating system.

WINDOWS 2000 (PRO / SERVER): SP1, SP2, SP3, SP4 WINDOWS XP_HOME: SP1, SP2 WINDOWS XP PRO: SP1, SP2 WINDOWS 2003: SP1

As shown in Table 2, WINDOWS-based operating systems distribute service packs to improve functionality, increase security, and fix bugs in other operating systems. The service pack proceeds in the direction of updating system files (or application files installed in WINDOWS) of the operating system pre-installed on the hard disk drive 240. Therefore, the system file 110 provided in the CD-ROM 100 should be loaded according to the service pack version of the operating system pre-installed in the repair target computer 200.

Next, when the operating system installed in the hard disk drive 240 is not determined based on the FAT file system (S322), the manager program 140 loads the NTFS file system into the memory provided in the computer 200 to load the NTFS file. Attempt to access the system (S323). The manager program 140 determines the windows-based operating system based on the NTFS file system. Accordingly, the manager program 140 starts the step S310 shown on the basis of the NTFS file system. This is because the Windows operating systems that support the NTFS file system are limited to Windows 2000 Pro to Windows Vista, and are not supported on Windows Me, Windows 98, and Windows 98se. Although not shown in detail, in the step S323 of accessing the NTFS file system, a drive letter for the hard disk drive 240 is assigned and reset. The FAT file system can access partitions (usually partitions for the C: \ drive) assigned to the hard disk drive 240 directly through the external storage medium 100, but the NTFS file system is not directly accessible from the outside. The manager program 140 assigns drive letters in the order of C, D, E, F, and G to partitions provided on the hard disk drive 240 having the NTFS file system. Each partition will be identified. For example, if the hard disk drive is divided into two partitions (volumes C and E), and the volume D is assigned to the optical recording / playback medium (for example, a CD-ROM drive), the manager program 140 is assigned to the volumes C and E. Can be assigned to C and D respectively. Next, even if the operating system pre-installed on the hard disk drive 240 is not determined even after the steps S310 to S320 based on the NTFS file system, the hard disk drive 240 itself is damaged or the operating system does not exist or It can be assumed that the partition itself is badly damaged. Therefore, the manager program 140 is a display device connected to the computer 200, and "the operating system cannot be found." After outputting the message, a device check message for the device (hard disk drive 240) check may be output (S324), and the execution of the program may be terminated.

In the present invention, by selectively loading the system file 110 provided on the CD-ROM 100 to the hard disk drive 240 according to the type of operating system and service pack type, a user of the computer 200 may reinstall or reinstall the operating system. Resolves an issue with reinstalling applications in the operating system. In addition, the present invention is a CD-RW, DVD-R, DVD-R (Dual Layer), DVD-RW, DVD + R, DVD + RW, DVD-RAM, Blu-ray Disc, floppy disk, USB in addition to the CD-ROM 100 Obviously, the storage device and the storage medium such as HD-DVD (High Density Digital Versatile Disc) can be stored and used in the form of a program.

As described above, the present invention repairs an operating system among system files of an operating system pre-installed in a hard disk drive through external storage media such as CD-ROM, DVD, USB, and Blu-ray Disc, when a problem occurs in an operating system installed in a computer. By reloading only the files necessary to the computer, problems with the computer's operating system can be solved simply and quickly.
