Modern PCs that shipped with Windows 8 or 10 have a feature called Secure Boot enabled by default. It keeps your system secure, but you may need to disable Secure Boot to run certain versions of Linux and older versions of Windows. Heres how to see if Secure Boot is enabled on your PC.
Rather than reboot and poke around in your UEFI firmware or BIOS settings screen, you can find this information in Windows itself.
Check the System Information Tool
Youll find this information in the System Information panel. To open it, open your Start menu and type System Information. Launch the System Information shortcut.
Select System Summary in the left pane and look for the Secure Boot State item in the right pane.
Youll see the value On if Secure Boot is enabled, Off if its disabled, and Unsupported if it isnt supported on your hardware.
With a PowerShell Cmdlet
You can also query this information from PowerShell. Why would you do this? With PowerShell Remoting, you could use PowerShell cmdlets to check if a remote PC has Secure Boot enabled.
This requires you run PowerShell as Administrator. Search for PowerShell in your Start menu, right-click the Windows PowerShell shortcut, and select Run as Administrator.
Run the following cmdlet in the PowerShell window:
Kod:
Confirm-SecureBootUEFIYoull see True if Secure Boot is enabled, False if Secure Boot is disabled.
If your PCs hardware doesnt support Secure Boot, youll see a Cmdlet not supported on this platform error message.
If you instead see a message saying Access was denied, you need to close PowerShell and relaunch it with Administrator permissions.
On a PC that does support Secure Boot, you can enable or disable Secure Boot from the computers UEFI firmware settings screen or BIOS confirmation screen. Youll usually need to restart the PC and press a key during the boot process to access this screen.
If the PC doesnt have Windows installed, you can check the Secure Boot state by poking around on this screenlook for a Secure boot option and see what its set to. If its set to On, Enabled, Standard, Default, or anything like that, Secure Boot is enabled.
