Abstract
A system and method is disclosed for recovering a boot image. Hardware instructions initiate a loading of a computer operating system on a computing device. During the loading of the operating system, multiple portions of boot code are verified and a determination is made whether each portion is valid. If a portion of boot code is determined to be invalid, a secure portion of the boot code is loaded to repair the invalid code and the loading of the operating system resumed.
