Abstract
A method, information handling system (IHS) and a recovery system for recovering an IHS from a secure boot authentication failure. The method includes retrieving, via a processor from a first memory device, a first unified extensible firmware interface (UEFI) driver associated with a first component/device of the IHS. The method further includes determining, via a secure boot process, if the first UEFI driver is an authenticated UEFI driver. In response to determining that the first UEFI driver is not an authenticated driver, a previously validated UEFI driver corresponding to the first component/device is retrieved from a second memory device. The method further includes loading the previously validated UEFI driver.
