7. How can the Customer Secure Boot Key be reset?
Secure Boot is a feature to ensure that only authenticated code can start on a platform. If you enabled
Secure Boot and created a Customer Secure Boot Key, simply disabling Secure Boot will not clear the
keys. You must also select to clear the Secure Boot Keys. Use the same procedure you used to create
the Secure Boot Keys, but make the selection to clear or delete all Secure Boot Keys.
Using HP Sure Start (select models only)
Select computer models are configured with HP Sure Start, a technology that continuously monitors your
computer's BIOS for attacks or corruption. If the BIOS becomes corrupted or is attacked, HP Sure Start
restores the BIOS to its previously safe state, without user intervention. Those select computer models ship
with HP Sure Start configured and enabled. HP Sure Start is configured and already enabled so that most
users can use the HP Sure Start default configuration. The default configuration can be customized by
advanced users.
