The invention allows easy actualization of starting up an operating system (OS) at an operating time in an information processing device (1) capable of exclusively operating a plurality of OSs, even in the case of switchover to the other OS after the OS has set this operating time. On the occasion of execution by a startup timer unit (21) stored with operating time set by a first or second operating system and causing the first operating system to transit from a stopping status to an operating status at the operating time, the operating time is read and temporarily stored (12) before an operation of the second operating system, and, after temporarily storing the operating time, the temporarily-stored operating time is written back to the startup timer unit (21) before the operation of the first operating system.
