Method and system of operating system recovery

A method of operating system recovery in a computer system, comprising the steps of:

• installing a recovery button implemented using a general purpose input/output interface on the computer system;
• providing a hard disk having a first disk partition and a second disk partition, in which the first disk partition has an original copy of an operating system and the second disk partition has a recovery system and an image copy of the operating system;
• and
• triggering the recovery button to reboot the computer system to the second disk partition, and execute the recovery system in the second disk partition to recover the operating system in the first disk partition by the image copy of the operating system.

A system of operating system recovery, comprising:

• a server system having a remote control agent to transmit a recovery instruction by the remote control agent;
• and
• a computer system coupled to the server system through a network, comprising;
• a basic input/output system;
• and
• a hard disk having a first disk partition and a second disk partition, in which the first disk partition has an original copy of an operating system and the second disk partition has an image copy of the operating system,
• wherein the computer system is allowable to receive the recovery instruction and reboots to the second disk partition and recovers the operating system in the first disk partition by the image copy of the operating system.

A method of operating system recovery in a computer system coupled with a server system through a network, comprising the steps of:

• providing a hard disk having a first disk partition and a second disk partition in the computer system, in which the first disk partition has an original copy of an operating system and the second disk partition has an image copy of the operating system;
• transmitting a recovery instruction by a remote control agent of the server system;
• receiving the recovery instruction by the computer system through the network;
• and
• instructing a BIOS to reboot the computer system to the second disk partition in response to the recovery instruction, and recovering the operating system in the first disk partition by the image copy of the operating system.
