PURPOSE: A multi-booting method using a flash disk is provided to boot a computer stably and quickly regardless of a network environment and recover a failure by downloading a new image from a remote server through the network in case that a problem is generated in the flash disk. CONSTITUTION: As the multi-booting is started, the initialization of the flash disk is discriminated(ST101). In the case that the flash disk is initialized, a boot image is downloaded from the flash disk(ST102). After download, it is checked that a downloaded AP(Application Program) image is normal and the booting is performed if the AP image is normal(ST104). If the AP image is abnormal, the boot image is downloaded from an FTP(File Transfer Protocol) server after initializing the network(ST106).
