A computer system is provided to boot the system even if a file storing information for other OSs(Operating System) or multi-booting is damaged by operating the OSs stored in each HDD(Hard Disk Drive) partition independently, make a user operate OS recovery easily and conveniently, and minimize risk for deleting the other OS when the user selects the incorrect partition. An HDD(40a) is divided into first, second, and third partitions(41a,42a,43a), and stores first and second OSs(OA1,OA2) to the first and second partitions. A power manager(20a) outputs a booting signal corresponding to a detected power button when a first or second power button(50a,51a) is selected. A routine storage unit(30a) initializes a system unit(10) and boots the system unit with the OS stored in the partition corresponding to the received booting signal when the booting signal is received from the power manager. The third partition stores first and second recovery images(OAR1,OAR2) for recovering the OSs. The power manager outputs a recovery signal corresponding to the power button selected together with a recovery button(61a) when one of the power buttons and the recovery button is selected at the same time. |
