Abstract
An apparatus using a software start-up method, selects execution-targeted software data to be used for starting execution of the start-up processing, out of software data stored in a first storage device; starts the execution of the start-up processing by using the execution-targeted software data; searches for another software data other than the execution-targeted software data, from software data stored in the first storage device; determines whether the another software data is changed from its initial-state; and, if the another software data is changed, selects initial-state software data as the initial state of the another software data from said at least one software data stored in a second storage device, reads the initial-state software data from the second storage device, and replaces the another software data stored in the first storage device with the read initial-state software data by overwriting.
