How to Disable UEFI Secure Boot in Windows 10

These days, if you buy a computer pre-installed with Windows, it comes with UEFI boot system. UEFI is not something that Microsoft invented, instead it is a protocol existing even before Windows 8. Some Mac devices have been using UEFI for a longer time.

With UEFI comes the feature of “secure boot” which boots only those bootloaders that are signed in to UEFI firmware. This security feature prevents rootkit malware and provides an additional layer of security.

The downside of secure boot is that if you want to boot from a Linux USB or if you want to use a bootable Windows USB, it won’t allow that. Sometimes, it may also create problems in dual booting with Linux.

The good thing is that you can easily disable the secure boot. All you have to do is to access the UEFI firmware settings, go to the Boot option and disbale it.

Don’t worry. I won’t leave you hanging like that. Let me show the steps in detail.

Disabling UEFI secure boot in Windows 10

Some systems don’t let you change the secure boot option without setting an admin password. I’ll discuss the issue in later steps.

Step 1: Access the UEFI settings

You may access the UEFI settings by powering on your system and using the F2/F10 or F12 keys at the boot time. If that doesn’t work, don’t worry. You can go to the firmware settings from within Windows as well. Here’s how.

Search for UEFI and go to Change advanced startup options in Windows menu.

Troubleshooting tip: Disable secure boot option disabled?

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. If that is the case, no need to panic just yet. There is a way around it.

Using arrow keys, move to Security tab. Look for Set Supervisor Password here.

Attention!

Either save this password somewhere safe where you can access it years later as well. Use a password manager or a cloud service or a draft in your email. Basically, you should not lose this password.
You may also clear the supervisor password after disabling the secure boot.

Once you have set the supervisor password, move to Boot tab now. This time you’ll see that you can actually access the Secure Boot option and change its value. Press the Enter key and change its value to Disabled.

  • hey i hope you can help me with this. so i went ahead to disable secure booting in windows 11. it looks different but thats all about it, i disabled it and exited the uefi settings. then Bitlocker popped up to me and i couldnt move on without entering my recovery key, which i am not finding anywhere in my microsoft account. how can i fix this? :)

  • If all you run is Windows only, there is no harm in leaving Secure boot on. I personally turned it off because I got tired of disabling when I was installing a Linux distro alongside Windows or even just Linux alone. Some sort of support it well, some do not. Best just to leave it off if you have any intention of installing an OS other than Windows.

  • I do not get any options for UEFI Firmware Settings, in the Advanced Options of Troubleshoot app.
    Have tried many times , with no success at all.
    I run Windows 10, desperate to setup Linux (Fedora Live on USB), with no luck.
    Help please.

    • That’s okay. You can access it after you reboot your system. When the logo of your system manufacturer comes up, press F2 or F10 or F12 or Del keys (it varies for manufacturers). You should be able to access boot settings.
