1. An information processing apparatus comprising:
a storage device that includes a first area storing normal startup firmware for normally starting the information processing apparatus, a second area storing update startup firmware for starting the information apparatus for update, and a common area that is used in a state where the information processing apparatus is started using the normal startup firmware or the update startup firmware; and
at least one processor that executes instructions stored in the storage device to:
perform a first startup where the information processing apparatus is started using the normal update firmware;
perform a second startup where the information processing apparatus is started using the update startup firmware;
during the first startup, in response to the first startup:
create the swap file in the common area and activate swapping in a state where a swap file is not present in the common area; and
not delete the swap file and maintain the activation of swapping in a state where the swap file is present in the common area; and
during the second startup, in response to the second startup, in the state where the swap file is present in the common area, delete the swap file from the common area.
