Turning off Secure Boot on Windows 11 might seem dead easy, but heaps of folks get stuck or confused along the way. Secure Boot is a security feature built into your BIOS that stops untrusted software from starting up. Sometimes, you’ve gotta disable it—like if you’re trying to install Linux or older hardware that doesn’t play nice with Secure Boot. The thing is, accessing BIOS settings can be a bit of a maze because every brand does it differently, with their own menu names and keys. No worries, though — this guide breaks it down step by step, with a few tips from actual experience.
Because, of course, Windows has to make it a bit tricky sometimes, so don’t be surprised if you hit a few dead ends or if menu paths are a tad different. Once you get it sorted, you’ll be able to boot from pretty much anything, but remember, this helps other folk get in more easily too — so be careful if security matters. Better to turn it back on when you’re done, especially if it’s just a temporary fix or for testing.
How to Disable Secure Boot on Windows 11
Check your manufacturer’s BIOS layout first
Before you reboot, have a quick look at your computer’s manual or support site for specific instructions. Different brands like Dell, ASUS, HP, or Lenovo all have different BIOS layouts, which can be confusing. Typically, you’ll press F2, F10, Del, or Esc during startup. Sometimes, there’s a message on the black screen just after you turn on that hints which key to hit. Keep pressing that key quickly once the machine powers on. On some setups, tapping gently and repeatedly works better than holding the key down.
Enter BIOS Setup and navigate
Once you get into BIOS, take a deep breath — it’s normal to see a jumble of settings. Look for a tab or menu labelled Boot or Security. It varies depending on the brand — some might have it under Advanced Mode or called Secure Boot Configuration. Checking your manual or quick online search for your model can save a lot of head-scratching. Use arrow keys or your mouse if supported. Sometimes, the option is greyed out or missing unless you switch to Advanced or Custom mode.
Find and disable Secure Boot
When you spot the Secure Boot option, select it. You’ll usually see options like Enabled or Disabled. Change it to Disabled. If it’s greyed out, you might need to set a supervisor password first or switch to CSM (Compatibility Support Module). That sometimes does the trick. Flipping that switch is usually all you need — feels pretty good once it’s done!
Save and exit, then reboot
After turning Secure Boot off, look for the Save & Exit option — often under the Exit menu. Confirm your choice, then the system will restart. Some BIOS setups might ask you to confirm with a Yes. Don’t stress if you see some warning messages — they’re normal when messing with BIOS. Once Windows loads again, you can double-check it’s off: open the System Information app and check the Secure Boot State. If it says “Off,” you’re laughing.
Sometimes it takes a reboot or two to get Secure Boot disabled, especially on certain models. So don’t worry if it doesn’t work the first go. Remember, turning it off does make your system a bit more vulnerable — so re-enable it when you’re finished if security is a concern.
Tips for Disabling Secure Boot in Windows 11
- Check your BIOS manual or online guides — each brand has its quirks.
- Backup your data — better safe than sorry when poking around in BIOS.
- Be aware of security risks — disabling Secure Boot lowers security, so keep that in mind.
- Re-enable Secure Boot once you’ve finished — just reverse the steps.
- Ask a mate or look online if you’re stuck — sometimes the menus aren’t as intuitive as they seem.
Frequently Asked Questions
What is Secure Boot anyway?
It’s Windows’ way of making sure only trusted, signed software runs during startup — like a bouncer for your PC that stops dodgy stuff from sneaking in at boot time.
Why would I need to turn it off?
If you’re installing Linux or an older version of Windows, Secure Boot can block that. Or maybe your hardware just doesn’t play along with it. In those cases, you need to switch it off.
How do I tell if it’s on or off?
The easiest way is to hop into System Information in Windows and check the Secure Boot State. Or, peek inside the BIOS — it’ll usually say if it’s Enabled or Disabled.
Will turning it off slow my PC down?
Nah, it won’t hurt your performance. It just lowers a bit of security — so make sure you’re okay with that.
Can I turn it back on later?
Definitely. Just head back into BIOS, re-enable Secure Boot, save your changes, and reboot. Easy as, though sometimes you’ll need to disable it first before turning it back on.

Wrap-up
Disabling Secure Boot isn’t too tricky once you know where to look, but BIOS menus can be a bit of a head-scratcher. Some machines you can flip it off in seconds, others take a bit of prying around. Basically, it’s giving your PC permission to boot from things outside the normal pathway — handy for installing or testing, but it does leave some security gaps. Take your time, back up your data, and switch it back on when you’re finished. Hopefully, this helps save you some hassle rather than chasing dead ends. Good luck, mate!
