Legacy Support—Enable/Disable. Allows you to turn off all legacy support on the computer,
including booting to DOS, 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 8.1 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 verifies kernels
during system start up, allowing you to use alternative operating 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 8.1 detects a serious error, it will interrupt the boot process automatically and
display advanced boot options.
From Windows 8.1, you can press
a device or troubleshoot your computer.
