Abstract

A method for starting an operating system rapidly by a hotkey includes the steps of: setting a hotkey for each operating system; executing a BIOS power on self test program; determining whether any hotkey has been pressed during execution of the power on self test program; activating a disk partition section which stores an operating system corresponding to a hotkey if the hotkey has been pressed; loading a master boot record; starting the operating system stored in the activated disk partition section.

Claims

1. A method for starting an operating system rapidly by pressing a hotkey, the method comprising the steps of:

setting a hotkey for each operating system;

executing a BIOS power on self test program;

determining whether any hotkey has been pressed during execution of the power on self test program;

activating a disk partition section which stores an operating system corresponding to a hotkey if the hotkey has been pressed;

loading a master boot record; and

starting the operating system stored in the activated disk partition section.

2. The method according to claim 1, further comprising the step of:

displaying prompt information about the set hotkeys.

3. The method according to claim 1, wherein the step of determining whether any hotkey has been pressed during execution of the POST program comprises:

starting the operating system defaulted by the BIOS.

4. The method according to claim 1, wherein the step of determining whether any hotkey has been pressed during execution of the POST program is executed by an interrupt command of the BIOS.

5. The method according to claim 4, wherein the interrupt command is INT 19.

6. The method according to claim 1, wherein the disk partition section is stored in the master boot record.

7. The method according to claim 1, wherein the operating system is a backup operating system corresponding to a destroyed operating system.
