Abstract
A method of booting an electronic device includes verifying communicable connection of a sender input/output terminal of the electronic device to a receiver input/output terminal of the electronic device, using a first boot loader executing on a computing processor of the electronic device. The method further includes reading a signature of a unique identifier of the electronic device from a removable storage device received by the electronic device, verifying the signature of the unique identifier of the electronic device, and allowing installation of a second boot loader on the electronic device when the signature is valid.
