HP 200 G1 manual Computer Setup-Power

Table A-3Computer Setup—Security (continued)

System Security	Virtualization Technology (enable/disable) - Controls the virtualization features of the processor.
	Changing this setting requires turning the computer off and then back on. Default is disabled.
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.
