Abstract

Disclosed are a computer system storing with a restoration program and a method of updating the restoration program, the computer system including: a first storage unit in which a predetermined program is installed, a second storage unit in which a restoration program corresponding to the program is stored, a communication unit which communicates with an external server, a user input unit, and a controller which stores an update file corresponding to the program received from the external server in the first storage unit, and updates the program installed in the first storage with the update file, the controller updating the restoration program of the second storage unit with the update file of the first storage unit if receiving a certain key input through the user input unit, and restoring the program on the basis of the updated restoration program.

Claims

1. A computer device comprising:

a communication unit which communicates with a server; and

a storage unit comprising a first storage area as a main partition in which at least one program and a management program are installed, and a second storage area as a hidden partition in which a restoration program configured to restore the program is stored, the management program configured to manage the restoration program,

wherein the hidden partition is not recognized by a first operating system as a normal drive and is accessed using a separate virtual file system interface;

wherein the management program receives a list of up-to-date programs through the communication unit from the server and selects at least one of the restoration program among a pre-stored restoration program list based on the received list of up-to-date programs, and

wherein the computer device boots a second operating system after receiving a restoration key through user input, compares program lists of the first storage area and the second storage area, and when the program lists are not the same, restores program files in the first storage area with the restoration programs in the second storage area.

2. The computer device according to claim 1, wherein the management program compares the pre-stored restoration program list with the list of up-to-date programs and selects the at least one of the restoration program according to comparison result.

3. The computer device according to claim 2, wherein the management program determines the restoration program to be selected when a software version of the restoration program is previous than a software version of corresponding program of the list of up-to-date programs.

4. The computer device according to claim 1, configured to operate under one of the first operating system and the second operating system,

wherein the first storage area is normally accessed under the first operating system or the second operating system, the second storage area is accessed under the second operating system, and the second storage area is determined to invalid storage and cannot be accessed under the first operating system.

5. The computer device according to claim 4, wherein the first operating system is installed in the first storage area and the second operating system is installed in the second storage area.

6. The computer device according to claim 4, wherein, if a predetermined key input is received from an user input unit under the first operating system, the management program boots up the second operating system to access to the second storage area and stores a selectively downloaded file based on a software version of the restoration program in the second storage area as the restoration program.

7. The computer device according to claim 4, the management program is able to restore the program with the restoration program under the second operating system.

8. The computer device according to claim 1, the management program transmits system information of the computer device to the server and requests for the list of up-to-date programs corresponding to the system information to the server.

9. A control method of a computer device including a storage unit comprising a first storage area as a main partition in which at least one program and a management program are installed and a second storage area as a hidden partition in which a restoration program configured to restore the program is stored, the control method by the management program comprising:

receiving a list of up-to-date programs from a server communicating with the computer device;

selecting at least one of the restoration program among a pre-stored restoration program list based on the received list of up-to-date programs;

wherein the hidden partition is not recognized by a first operating system as a normal drive and is accessed using a separate virtual file system interface; and

wherein the computer device boots a second operating system after receiving a restoration key through user input, compares program lists of the first storage area and the second storage area, and when the program lists are not the same, restores program files in the first storage area with the restoration programs in the second storage area.

10. The control method of the computer device according to claim 9, wherein the selecting comprises comparing the pre-stored restoration program list with the list of up-to-date programs and selecting the at least one of the restoration program according to comparison result.

11. The control method of the computer device according to claim 10, wherein the comparing comprises determining the restoration program to be selected when a software version of the restoration program is previous than a software version of corresponding program of the list of up-to-date programs.

12. The control method of the computer device according to claim 9, the computer device is configured to operate under one of the first operating system and the second operating system,

wherein the first storage area is normally accessed under the first operating system or the second operating system, the second storage area is accessed under the second operating system, and the second storage area is determined to invalid storage and cannot be accessed under the first operating system.

13. The control method of the computer device according to claim 12, wherein the first operating system is installed in the first storage area and the second operating system is installed in the second storage area.

14. The control method of the computer device according to claim 12, further comprising boots up the second operating system to access to the second storage area if a predetermined key input is received from an user input unit under the first operating system,

wherein the downloading comprises storing a selectively downloaded file based on a software version of the restoration program in the second storage area as the restoration program.

15. The control method of the computer device according to claim 12, the management program is able to restore the program with the restoration program under the second operating system.

16. The control method of the computer device according to claim 9, the receiving comprises transmitting system information of the computer device to the server and requesting for the list of up-to-date programs corresponding to the system information to the server.
