Abstract
An information handling system is configured to support first and second boot sequences, which invokes first and second bootloaders respectively. The bootloaders may be stored in an NVMe storage boot partition. Each bootloader may be associated with a corresponding encryption key generated by a trusted platform module, which may seal the first and second keys in accordance with one or more measurements taken during the respective boot sequences. The system determines whether a boot sequence in progress comprises is to invoke the first or second bootloader. The system then unseals the appropriate encryption key to access the appropriate bootloader. The first bootloader may be a host OS bootloader and the second bootloader may be for a recovery resource invoked when the host OS fails to load. The recovery resource may enables BIOS to connect to a remote store and download an image via a HTTP mechanism.
