entered, the hard drive will remain inaccessible until one of the passwords is successfully provided during a subsequent cold-boot sequence.

Secure Boot

This is a feature of Windows 8.

Configuration

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 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 Windows 8, you can press Shift and select Restart to access the screen that lets you boot to a device or troubleshoot your computer.
