Abstract
A system and method is disclosed for recovering a boot image from a secure location. Hardware instructions initiate a sequence of boot cycles to launch a computer operating system on a computer-enabled device. During the boot cycles, multiple levels of boot code are verified and a determination is made whether each level is usable by the device. If a level of boot code is determined to be unusable, a secure copy of the boot code is loaded from a secure read-only location to repair the unusable code to launch the computer operating system.
