Tutorial to disable UEFI secure boot in Windows 8

These days, if you buy a computer pre-installed with Windows, you’ll end up with either Windows 8 or Windows 8.1. Starting with Windows 8, Microsoft replaced BIOS with UEFI. UEFI is not something that Microsoft invented, instead its a protocol in existence before Windows 8. Some Mac devices have been using UEFI for some time now.

With UEFI comes the feature of “secure boot” which boots only those boot loaders that are signed in to UEFI firmware. This security feature prevents rootkit malware and provides an additional layer of security. But it has a down side, if you want to dual boot Windows 8 with Linux, Secure Boot will not allow it. Therefore it is advised to disable secure boot in Windows 8 to allow dual booting with Linux.

Disable UEFI secure boot in Windows 8 and 8.1

There have been too many noises around secure boot. Because of these rumors, some people almost believed that dual boot to Linux is not possible with pre-installed Windows 8. While that is true for Arm PCs, secure boot can be disabled in Intel based system. Honestly, disabling UEFI secure boot is not at all a herculean task and same can be said for dual booting Linux with Windows 8 UEFI.

While it is fairly straight forward to access BIOS settings, you press F10 or F12 at boot time, it’s not the same case with UEFI. To access UEFI settings, you’ll have to go from within Windows. Let’s see how to access UEFI settings to disable secure boot in Windows 8.

Step 1: Go to PC settings

Open the settings charms in Windows by pressing Windows+I keys. At the bottom, you’ll see the option of Change PC settings. Click on it.

Step 1 to disable secure boot in Windows 8 or 8.1

Step 2: Go to Advanced startup

There will be a slight difference in PC settings for Windows 8 and Windows 8.1. Depending upon which one you are using, you can follow the respective procedure described below:

Windows 8: In Windows 8, you need to go to General PC settings and select Advanced startup and then click on Restart now:

Window 8.1: In Windows 8.1, go to Update and recovery from left sidebar:

accessing UEFI secure boot in windows 8.1

Then click Restart now under Advanced startup:

Don’t worry! It won’t restart right after it, instead it will provide some option that you will see on next boot.

Step 4 Access UEFI settings

After you have clicked Restart now button, you will be presented with some options to choose from in the next screen. Select Troubleshoot here:


In Troubleshoot menu, select Advanced options:


In Advanced options menu, choose UEFI Firmware settings:


Next, click on Restart button to reboot your system in UEFI settings which ‘may’ seem to have similar interface as BIOS.

Step 5: Disable secure boot in UEFI

By this time you must have been booted in to UEFI utility. You can change various settings here but all we want to do right now is to disable secure boot option to allow dual booting of Ubuntu or any other Linux

Move to Boot tab, there you’ll find Secure Boot option which is set to enabled. Use the arrow key to go to Secure Boot option and then press enter to select it. Use + or – to change its value. Confirm it when prompted. Press F10 to save the changes and exit the UEFI settings.

As mentioned by some readers in the comments, if you are using an Acer laptop, you might see that option to disable secure boot has been greyed out. Please follow this tutorial to disable secure boot in Acer notebooks.

Next you’ll be booted in to Windows normally. Now you should be able to dual boot Windows 8 with Ubuntu or other Linux OS. I’ll be writing on how to dual boot Ubuntu with Windows 8 UEFI in coming days. Stay tuned.

I hope this tutorial helps you to disable secure boot in Windows 8 and Windows 8.1. Any questions or suggestions are always welcomed. Feel free to drop a comment.

    Did this last week!! Had to dig for the info.. Good Work foss!!

    • Abhishek Prakash

      By the way.. I did not get the link to your flicker account (for 14.04 wallpaper). Could you please post the link on Facebook page or Google+ page (if you use either)?

      • suinjato

        • Abhishek Prakash

          Got it.. thanks :)

  • Senior Dev.Khalid

    Hi please answer me I’ll format my hard and repartion it and i’ll install windows8 then Ubuntu 14.04 LTS should I do that or if i managed to choose windows or Ubuntu in this case i won’t need to disable this feature?
    thanks in dvance

    • Abhishek Prakash

      Hi Khalid,

      I did not understand your question correctly. If you have Windows 8 pre-installed, you should disable this secure boot in order to dual boot it with Linux.

      If you have a laptop on which you plan to install Windows 8 first and then Ubuntu, you don’t need to bother with UEFI as it won’t be there anyways.

      I hope it clarifies.

  • Akshay

    Advance Option Doesn’t show UEIF Setting.WHY????

    • Abhishek Prakash

      It must, try to follow the exact steps.

      • matyot

    uefi settings is not showing the secure boot under the boot tab.

    • Muhammed Butt

      possible if you using an older machine without uefi

  • Venky Govind

    Hi.. I’m using a recent ASUS N550JV laptop. The BIOS option to disable Secure Boot has been greyed out (unable to change it from “enable” to “disable”). Kindly help!!

    • Abhishek Prakash

      Try to disable “legacy support” first and then see if you could disable secure boot.

      • Venky Govind

        I have attached screenshots of my bios for your info…

        It says Secure boot can be enabled only when platform key is user and launch CSM is disabled. So I think I just have to enable CSM to disable secure boot… Am I right?

  • yeshwanth

    • Abhishek Prakash

      I’ll have to check if there are different kind of settings from different manufacturer.

  • Naut

    Hi, I have a problem with my pc. It doesn’t show the security tab in the bios. and I cannot see uefi settings in the settings.

  • Rodrigo

    • matyot

      Hello Rodrigo,
      I can’t see UEIF settings, unther Startup Settings I have some choices but no one involves UEFI or boot …
      Do you have some additionnal advices?

  • Bethany

    Abhishek: Thank you for the info!! To anyone who can’t find the Secure Boot option under the Boot menu, check under the security tab, that’s where it was on my system.

    • Mathearo

      Thank man!! You just saved my life!!!

      • Sébastien

        Same for me ! Thanks!

  • Ashok Gupta

    Mr.Abhi No UEFI Firmware settings in Advance Options !!!!

  • michael

    doesn’t work on a Toshiba P850. The secure book option is greyed out.

  • Carl Gitchel

    I am one of those who did not find UEFI among the Advanced Options. However, since this laptop was an old Vista machine I suspect UEFI was not part of the Windows 8 upgrade, therefore not present in the 8.1 overhaul. Which may explain the slow speed problems I have with Windows 8. When I hit F2 on reboot I was taken to a BIOS screen, so I assume this will behave fine on a dual boot setup.

    • Abhishek Prakash

      Yes. Indeed you don’t have UEFI but the older BIOS. You can simply dual boot with bothering about disabling secure boot.

  • T C Yağmur Birdinç

    After I booted in UEFI mode, I couldn’t find anything about “Secure Boot” but I could change the boot order starting with CD/DVD-ROM. After that I could boot with ubuntu boot DVD and install it. Important thing was to boot in EUFI mode; so thank you :)

    • Abhishek Prakash

      Welcome :)

  • sderose

    Step 5: “UEFI Firmware Settings” — no such item is there.

    • Mani

      If u get 5 options instead of the uefi settings, select the bios setup

  • koyax

    UEFI Firmware settings not showing up… The other options are there though
    Any ideas?

  • Octachoron

    When I get to step 5, instead of a UEFI utility, I encounter a blue startup menu with options like press F1 for system information, f2 system diagnostics, f9 boot device options, f10 bios setup, f11 system recovery, f12 network boot. How do I get to the UEFI utility from this?

  • twado

    pure help foss. tanx!!

  • Heemanshu

    there is no secure boot option to disable in my bios settings . i am having asus laptop

  • Jose Gato Luis

    Abhishek great tutorial.

    For the people having problems disabling secure boot (in my case an Acer Aspire):

    If you cannot disable Secure Boot, try setting a supervisor password in the security tab. After that you can disable secure boot.

    Abhishek maybe you could update the tutorial

  • Telmo “Trooper”

    Thank you for this quick tutorial, you saved me a lot of trouble.

  • Abraham Lincoln Brigade

    Microsoft says that you MAY have to disable Secureboot I wonder. It also says that some machines are configured such that you can’t. I have not gotten there yet but I suspect I won’t have that prob on an HP. Would be nice to have a work around up my sleeve though. Reference

  • Don Boss Jaime

    I’m using windows 8, after disabling secureboot my unit restarted as expected but did not continue to start menu. How long will this usually take to proceed to start menu?

  • Aditya Wisnu Pradipta

    Hey guys. Don’t know whether I’m doing something wrong or this how-to is outdated.
    I have Elitepad 900 from HP with Win 8.1 (RT, I think)
    I want to get rid of the freakin system and go with Android, if possible.

    I followed your steps, but step 5), it doesn’t happen.
    I did everything as you described, but when I click restart, I will get login screen and after unlcocking it, start menu…I guess, the UEFI crap should’ve been before, right?
    What am I doing wrong?

    “Ubuntu Website Warns Windows 8 Users: Don’t Use WUBI”

    Anyone have any experience installing Ubuntu on a Windows 8 ASUS notebook?

    Can you install the new version of Ubuntu (14.10) if it’s 64-bit, or are there still issues?

  • cact25

    I hav an XP machine which I installed Win 8.1 on. I cannot find a boot.ini file, yet on bootup, it displays a Win 8 startup menu With Win 8 first and “older operating systems” next.

  • Dying_in_this_Crap_World

    Big Issue: Cannot access bios after enabling secure boot, what a load of motherfucking bull shit.

    • Abhishek Prakash

      Calm down!!

      At the boot, try F0, F2, F10 or Del button. Your BIOS is always accessible.

  • Tony Q. King

    Hi- it’s me again! Good article on disabling UEFI in Windows.
    But right now I have this UEFI crap in my Grub. And As I have an old mboard and BIOS, –
    aqk@aqk-785GM-P45:~$ sudo dmidecode | grep ‘Vendor|Version: V|BIOS Revision|Processor’
    [sudo] password for aqk:
    Vendor: American Megatrends Inc.
    Version: V11.6
    BIOS Revision: 8.15
    Processor Information
    Type: Central Processor
    Version: AMD Phenom(tm) II X2 560 Processor

    I wish to get rid of the UEFI and have a simple GRUB as I had before.
    Any ideasd on how to get it off of Ubuntu and Grub?

    You can see my today’s query at ….

    OR! Would you suggest I flash my BIOS with latest upgrade? (I am not sure if there is one)

    This is great for some, so thanks.
    My system, however is booting to a flashing screen of solid changing colours. This is where I’d normally use Knoppix DVD to boot and then copy my important files to another location. Obviously I can’t do this now as I haven’t previously disabled UEFI within Windows 8 (which I truly hate). Looks like I’m snookered. Poxy Microsoft strikes again.

  • Wolfgang Pfeiffer

    Provided I didn’t miss anything:
    On Windows 8.1 to get into step 4 – UEFI settings – it might be enough tosimply press the power button (see picture), select restart and at the same time hold down the Shift key.

    • Abhishek Prakash

      This may vary for different manufacturer and hence I wrote the generic one :)

    Abhishek, I hope you still read these messages and can help me! I am running on windows 8.1 using an Asus i7-4790S. When i try to disable secure boot, it is grayed out and you cannot change it. There is no supervisor password to set, only an administrative and user password. I have made/installed both of those passwords and still am unable to change it. Here are some screenshots of the settings on those screens i hope you can help :D.

    • Abhishek Prakash

      Hi Ricky,

      Sorry for my late reply. When there are too many comments, I miss a few of them. I presume you tried setting up the supervisor password or enabling the legacy boot mode on?

  • David Warner

    you don’t need to go down that road anymore,im on a hp desktop and when win 8 came out you had to do all this from with in with new ubuntu 14.04 included i can boot Ubuntu from usb from starting PC,and also now when i duel boot ubuntu mate it gives me the old option of installing windows side by side during the install of mate,which win 8 did not do when it first came out 😉

  • Dickson Pareja

    will this made my windows start slower? / Won’t I be able to update to windows 10 when it comes out? I read that it will require secured boot enabled
