<p>The present invention relates to a bootloader execution method duplexing a single stage bootloader to solve the system booting errors which can occur when the bootloader is upgraded and a device thereof. The bootloader execution device stores a first bootloader image and a second bootloader image generated by duplexing the first bootloader image to a bootloader storage unit, determines whether a currently executed bootloader image loaded in an auxiliary storage unit separately arranged from the bootloader storage unit is the first bootloader image or the second bootloader image, conducts a validity check operation for the second bootloader image when the bootloader image currently being executed on the bootloader storage unit is the first bootloader image, loads the second bootloader image onto the auxiliary storage unit when the second bootloader image passes the validity check to execute the loaded image, and loads and executes the first bootloader image on the main storage unit when the second bootloader image fails to pass the validity check.</p> |
