Turning on Secure Boot in Windows 11 isn’t just some fancy feature — it helps keep your PC safe from dodgy malware trying to load before Windows even starts. But fair dinkum, it’s not a simple flick of a switch. You’ll need to dive into your BIOS or UEFI firmware — which on some computers can feel like trying to crack a secret code. If Secure Boot isn’t enabled by default, you might hit a snag, especially if your system is still running in Legacy mode or hasn’t been updated. No worries, though — this guide will walk you through it step by step so you’re not left scratching your head. Once you’re done, your machine will have an extra layer of security worth the effort.
How to Enable Secure Boot in Windows 11
Getting Secure Boot sorted is a bit of a process, but once it’s done, it’s like putting a deadlock on your front door. Keeps out the baddies, makes sure your system boots up the right way, and honestly, it’s a good habit if you give a toss about security. Just keep in mind, sometimes you might need to disable other features like Fast Boot or switch from Legacy to UEFI mode — because Windows can be a bit cranky about that sort of thing.
Check if Your System Supports Secure Boot and Get Ready
- First off, see if your PC can do Secure Boot. Some older models might not support it, or the firmware might be missing the option altogether.
- Make sure your firmware is up to date. Head to the manufacturer’s website and look for BIOS/UEFI updates. Sometimes, they roll out new firmware with Secure Boot support.
- Backup your important stuff. Seriously, just in case. Changing BIOS settings isn’t a walk in the park, but better safe than sorry.
How to Access BIOS/UEFI Settings
This is where it gets a bit annoying. You need to reboot your PC and press a key like F2, Delete, F10, or Esc during startup. The exact key depends on your hardware. Usually, the first splash screen gives you a hint (“Press Del to enter setup” or similar). If you’re stuck, just Google your computer model + “enter BIOS”.
Navigate to Boot or Security Tab
- Inside the BIOS, look for tabs called “Boot”, “Security”, or sometimes “Authentication”. BIOS layouts vary a lot — some are more confusing than others.
- If you see Secure Boot, beauty. If not, check if your firmware is set to Legacy Boot. If it is, switch it to UEFI Mode first. That’ll usually be under *Boot Mode*, *Boot Option*, or similar.
Enabling Secure Boot and Switching to UEFI
- Find the Secure Boot toggle and switch it to Enabled. Usually just selecting the option does the trick — might be a dropdown or a checkbox.
- If your system’s still in Legacy mode, switch it over to UEFI — Secure Boot only works with UEFI. On some systems, changing this might mean disabling and re-enabling TPM or Secure Boot later (check your motherboard manual if you’re unsure).
Save, Exit, and Confirm
Once you’ve got Secure Boot turned on, save your settings — usually F10 or select Save & Exit. Your PC will reboot with Secure Boot hopefully activated. Sometimes it doesn’t work first go, so you might need to go back in and tweak a few bits. No worries, it’s normal for things to take a couple of attempts to get right.
Tips for Enabling Secure Boot in Windows 11
- Make sure your firmware supports it. Some machines — especially older or custom builds — might not play ball without a firmware update.
- Be aware that enabling Secure Boot can cause issues if you’re dual-booting Linux or other OSes not signed for Secure Boot. Might need to sign your bootloader or just turn it off.
- Disable Fast Boot sometimes, as it skips over certain checks making it tricky to get into BIOS.
- After you switch it on, check it’s active: reboot, then run Windows Security or check in msinfo32.exe under Secure Boot State.

Could be your hardware’s a bit old, or you need a firmware update. Sometimes, it’s just not supported on your motherboard or you’re stuck in Legacy mode. Check your manual or BIOS to be sure — no magic tricks here.
Will enabling Secure Boot slow my PC down?
Nah, it’s not about speed. It’s about security. You probably won’t notice any difference, but in rare cases, if things aren’t set up right, it might cause booting issues.

- Check or switch to UEFI mode, disable Fast Boot if needed.
- Find and enable Secure Boot.
- Save your settings and reboot.
