To clear preboot authentication credentials for all enrolled users, do the following from the ESC Preboot Manager > Advanced screen (or in the Dell BIOS): • a. If both the BIOS system and BIOS admin passwords are set, change the BIOS admin password to a null value. • b. If the BIOS system password is set and the BIOS admin password is not set, first change the BIOS system password to null and set the BIOS admin password to a value. Then change the BIOS admin password to null.
