Electronic device and method of starting electronic device

1. A method of starting an electronic device connectable to other devices, the method comprising:

detecting whether the electronic device is connected to one device among the other device, the one device being a different device from the electronic device;

detecting identification information of the one device in response to detecting that the electronic device is connected to the one device;

comparing the identification information with specified identification information of a specified device;

enabling loading of an OS (Operating System) and execution of the OS when the identification information and the specified identification information are matched; and

disabling the loading and the execution when the identification information and the specified identification information are not matched.

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

notifying that disabled in response that the loading and the execution are disabled.

3. The method according to claim 2 , wherein the electronic device does not include a display device, and the notifying further comprises notifying that the loading and the execution are disabled using a light-emitting diode with a variable color or a variable blinking cycle.

4. The method according to claim 1 , further comprising:

performing user authentication in response that the loading and the execution are enabled.

5. The method according to claim 1 , wherein

the electronic device is able to execute a BIOS (Basic Input Output System),

the detecting is implemented by the BIOS, and

the method further comprising:

performing user authentication by the OS in response that the loading and the execution are enabled.

6. An electronic device connectable to other devices, the electronic device comprising:

a storage device;

a main memory; and

a controller that detects whether the electronic device is connected to one device among the other devices, detects identification information of the one device in response to detecting that the electronic device is connected to the one device, compares the identification information with specified identification information of a specified device, enables loading of an OS (Operating System) from the storage device into the main memory and execution of the OS when the identification information and the specified identification information are matched, and disables the loading and the execution when the identification information and the specified identification information are not matched, the one device being a different device from the electronic device.

7. The electronic device according to claim 6 , wherein,

in response that the controller disables the loading and the execution,

the controller notifies that the loading and the execution are disabled.

8. The electronic device according to claim 7 , wherein

the electronic device does not include a display device, and

the controller notifies that the loading and the execution are disabled using a light-emitting diode with a variable color or a variable blinking cycle.

9. The electronic device according to claim 6 , wherein,

the controller performs user authentication in response that the loading and the execution are enabled.

10. The electronic device according to claim 6 , wherein

the electronic device is able to execute a BIOS (Basic Input Output System)

detecting whether the electronic device is connected to the one device and detecting the identification information of the one device are implemented by the BIOS, and

the controller performs user authentication by the OS in response that the loading and the execution are enabled.

11. An electronic device connectable to other devices, the electronic device comprising:

a storage device;

a main memory; and

a controller that detects whether the electronic device is connected to a set of devices among the other devices, detects items of identification information of the set of devices in response to detecting that the electronic device is connected to the set of devices, compares the items of the identification information with items of specified identification information of a set of specified devices among the other devices, enables loading of an OS (Operating System) from the storage device into the main memory and execution of the OS when all the items of the specified identification information are included in the items of the identification information, and disables the loading and the execution when at least one of the items of the specified identification information is not included in the items of the identification information, the set of devices being different devices from the electronic device.
