Secure Boot - Enable or Disable in UEFI

How to Enable or Disable Secure Boot in UEFI

UEFI (replaces BIOS) has a firmware validation process, called secure boot, which is defined in Chapter 27 of the UEFI 2.3.1 specification. Secure boot defines how platform firmware manages security certificates, validation of firmware, and a definition of the interface (protocol) between firmware and the operating system. Secure boot prevents “unauthorized” operating systems and software from loading during the startup process.

Quick summary

  • UEFI allows firmware to implement a security policy
  • Secure boot is a UEFI protocol not a Windows 8 feature
  • UEFI secure boot is part of Windows 8 secured boot architecture
  • Windows 8 utilizes secure boot to ensure that the pre-OS environment is secure
  • Secure boot doesn’t “lock out” operating system loaders, but is a policy that allows firmware to validate authenticity of components
  • OEMs have the ability to customize their firmware to meet the needs of their customers by customizing the level of certificate and policy management on their platform
  • Microsoft does not mandate or control the settings on PC firmware that control or enable secured boot from any operating system other than Windows

For more information about secure boot, see:



This tutorial will show you how to enable or disable secure boot in your PC's UEFI settings.

Any PC with a Windows 8 logo sticker has secure boot enabled by default. Secure boot can make Windows 8 very resistant to low-level malware such as rootkits.

If you have secure boot enabled, you may sometimes need to disable secure boot first before being able to boot from a USB flash drive depending on your UEFI firmware settings.


If you would like to post screenshots of your motherboard's secure boot settings, then please do. Here are some others posted so far:


warning   Warning
Arm based Windows RT PCs and devices will have a locked boot loader, so you will not be able to disabled secure boot on them.

If you have a Windows 8.1 device that has the device encryption feature turned on and disable secure boot, then you may not be able to access the data on the disk until you enable secure boot again.

Do not enable secure boot with Windows 7, Vista, or XP installed. If you do, these OSs will not boot until secure boot is disabled.


EXAMPLE: "SecureBoot isn't configured correctly" watermark in Windows 8.1

SecureBoot_isn't_configured_correctly_watermark.jpg

You will see this watermark on the bottom right corner of your desktop if you have Windows 8.1 installed with UEFI and secure boot is not configured correctly even when enabled. To remove this watermark, you will just need to enable and configure secure boot correctly.

Sometimes the watermark doesn't go away even if you correct the settings in UEFI/BIOS or your BIOS doesn't support this feature at all.

Microsoft has acknowledged this issue and released a hotfix KB2902864 to solve this problem. Once you install this hotfix, it'll remove the annoying watermark from your Windows 8.1 desktop.

Windows 8.1 users who have the "SecureBoot isn't configured correctly" watermark on the desktop, can download this hotfix from the following links:

Update removes the "Windows 8.1 SecureBoot isn't configured correctly" watermark in Windows 8.1 and Windows Server 2012 R2

My Intel DZ77GA-70K motherboard supports SecureBoot and even though I'm booting to UEFI, I'm still not ready to try the SecureBoot option in the BIOS and I've left it unselected. Maybe one day when I'm feeling lucky?

Hello Art,

Secure Boot is an extra layer of protection to help protect your system from anything malicious during boot before Windows and most AV programs kick in their protection.

It'll be worth having enabled when you like. :)

New Asus K55 laptop has under BIOS Security tab>I/O Interface Security>Secure Boot state>Enabled

but the cursor will not go to it.

Just below that there's Secure Boot Control>Enabled which description is Secure Boot flow control and allows changing to Disabled.

How exactly do I disable Secure Boot in this case? Do I need to give it an Admin Password first?

Hello Greg,

You might see if disabling "Secure Boot Control" will then let you disable "Secure Boot state".

If not, will it let you use the arrow keys on the keyboard to navigate to the Secure Boot option, then press Enter to select it to toggle enable/disable?

Do I need CSM for Win7 dual boot even if I am using UEFI install method? I thought it was for Legacy BIOS only. Is this because of using a flash stick for install? It looks like it.

Man I never thought I'd need to go back to FAT32 fomatting. Are you sure this is progress? :think:

Oh well it should work on Legacy too. I can just copy all my files off and back on anyway.

I am wanting to keep the factory preinstalled 8 for the 15-day trial period on this laptop because of assurances the optimization done for 8 will compensate for the bloatware, but you know me so I'm already scheming to multi-boot an 8 Clean Install as soon as I do 7.

But I just can't handle Metro even after promising an open mind, so I've already got Win7StartforWIn8 installed.

What options do you have in CSM, UEFI or UEFI & Legacy is needed.


Found some Asus K55N screenshots, but not options in CSM.

Thanks Ray. What's buggin me now is that nothing in the Manuals refers to the 16gb Recovery Drive it offers to make under Recovery. I went ahead and sacrificed my installer stick for this since i have others, and it confirms it is copying the Recovery partition, but I can't find anything on the web about how this is run to recover to Factory condition.

I assume its bootable since it formats the stick wiping everything out. Anyone familar with it? I wonder why Asus keeps it such a big secret.

Reinstall is based on RESET.

This is a tutorial by Lenovo using the Windows 8 USB Drive Recovery app.

Methodology to create Recovery Media and reload a Lenovo Think system with Microsoft Windows 8 preload


Lenovo said:
NOTE: From this point forward in the recovery process, the choices for actual operating system recovery depend on the existing state of the computer hard drive.

Below are the instructions if there is an existing Microsoft Windows 8 install on the hard drive.
1.Select the target operating system of Microsoft Windows 8 to reload over existing Lenovo preload.
2.Select "Yes" to repartition the drives or "No" to keep existing partitions. For a clean install, the drives should be repartitioned.
3.Select "Fully Clean the drive".
4.Click Reset to begin the process.
5.The reset/recovery process takes approximately 90 minutes.
6.Once the reset/recovery is complete, the system will reboot into Microsoft Windows 8.

Below are the instructions if the hard drive is blank.
1.Select "Yes" to repartition the HDD or "No" to keep the existing partitions.
2.Click either choice, but these instructions follow the repartition scenario.
3.Select "Fully Clean the drive" as this will take several minutes to complete.
4.Click Reset to begin the process.
5.The reset/recovery process takes approximately 90 minutes.
6.Once the reset/recovery is complete, the system will reboot into Microsoft Windows 8.

I ran Reset to test it and it did a full Factory Recovery. What I still don't understand is how the Recovery USB drive fits in since it won't boot even under CSM or UEFI.

Also above it gives steps for if the HD is blank. But where does it get the Factory Image then if the Recov partiiton is gone from the HD? If it's still using Reset how does it tap the image on the stick?

I am rewriting the stick again to see if I can get it to boot. Will also check if Reset will pick it up.

Basically the factory recovery is a reset like in the tutorial below. A Reset can be done from within Windows or Winre at boot.

http://www.eightforums.com/tutorials/2302-reset-windows-8-a.html


When you start to do a Reset, Windows will automatically look for connected installation media. If you don't have the recovery USB connected, then Windows will prompt for you to connect it or installation media to be able to start the Reset.

What issue are you having?

Does it say you have secure boot enabled (true) in step 1 and 2 in that tutorial?

If true, the you would want to disable secure boot by using step 3 in that tutorial.

So if we don't have UEFI, how does one enable Secure Boot?

Hello Gregor, and welcome to Eight Forums.

No worries. If your motherboard doesn't have UEFI firmware, then you won't have Secure Boot either. :)

Hi Brink, thanks for the quick reply,

So I am trying to downgrade Windows 8 to 7 and I'm following this guide: http://www.eightforums.com/tutorials/13326-downgrade-windows-8-windows-7-a.html

Do you have a new PC with Windows 8 Pre-installed?
