1. A storage device comprising:
a memory device including one or more boot partitions configured to store boot data for executing an operating system; and
a memory controller coupled to the memory device and configured to perform, upon receiving power, a rebuild operation to restore a first part of system data including active boot partition information associated with an activated boot partition among the one or more boot partitions and provide the active boot partition information to a host and to restore a second part of system data after providing the active boot partition information,
wherein, upon receiving, by the memory controller, from the host, a boot partition read request based on the active boot partition information, the memory controller transmits, to the host, the boot data stored in a boot partition corresponding to the active boot partition information,
wherein the first part of system data includes system data for performing an internal operation of the memory device and the memory controller according to a read request, a write request, or an erase request from the host, and
wherein the second part of system data includes system data for performing a background operation of the memory device and the memory controller.
