HP Z230 Workstation - Maintenance and Service Guide

◦
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 detects a serious error, it will interrupt the boot process automatically and
display advanced boot options.
From the Start screen, you can press shift and select Restart to boot to a device or troubleshoot
your computer.
