Legacy Support—Enable/Disable. Allows you to turn off all legacy support on the computer,
including booting to DOS, running legacy graphics cards, booting to legacy devices, and so
on. If set to disable, legacy boot options in Storage > Boot Order are not displayed. Default
is enabled.
Secure Boot—Enable/Disable. Allows you to make sure an operating system is legitimate
before booting to it, making Windows resistant to malicious modification from preboot to full
OS booting, preventing firmware attacks. UEFI and Windows Secure Boot only allow code
signed by pre-approved digital certificates to run during the firmware and OS boot process.
Default is disabled, except for Windows 8 systems which have this setting enabled. Secure
Boot enabled also sets Legacy Support to disabled.
Key Management—This option lets you manage the custom key settings.

Clear Secure Boot Keys—Don't Clear/Clear. Allows you to delete any previously loaded
custom boot keys. Default is Don't Clear.

Key Ownership—HP Keys/Custom Keys. Selecting Custom Mode allows you to modify
the contents of the secure boot signature databases and the platform key (PK) that

systems. Selecting HP Keys causes the computer boot using the preloaded HP-specific
boot keys. Default is HP Keys.
Fast Boot—Enable/Disable. Fast boot disables the ability to interrupt boot, such as pressing f
keys to access items before the operating system loads. Default is disabled.
NOTE: If Windows 8 detects a serious error, it will interrupt the boot process automatically
