The loader requires Secure Boot to be turned off in your BIOS. If it's still enabled, the loader will notify you. Here's how to disable it.
1. Get into your BIOS
Two ways to enter your BIOS / UEFI settings.
Windows 11
- Open Settings
- Go to System > Recovery
- Under Advanced startup, click Restart now
- After the PC restarts, choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart
Windows 10
- Open Settings
- Go to Update & Security > Recovery
- Under Advanced startup, click Restart now
- After the PC restarts, choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart
Or press a key at boot
Restart your PC and mash Del, F2, or F10 before Windows starts loading. Which key depends on your motherboard - watch the boot screen for a hint like "Press Del to enter setup". Laptops sometimes use F1 or Esc.
2. Disable Secure Boot
- Navigate to the Boot tab. Some BIOS put Secure Boot under Security or Authentication instead.
- Find Secure Boot (sometimes labeled Secure Boot State or Secure Boot Control) and set it to Disabled.
- Save and exit (usually F10 or an on-screen Save & Exit option).
If you can't find Secure Boot in the menus, most modern BIOS interfaces have a built-in search - try pressing F9 and searching for "secure boot".
3. Verify it worked
Once Windows boots back up, open msinfo32 (Windows key + R, type msinfo32, Enter). Look for these in the System Summary:
- BIOS Mode: should say UEFI
- Secure Boot State: should say Off
Manufacturer-specific guides
If you can't find the setting using the above, your motherboard or PC manufacturer's support site usually has a walkthrough with screenshots. Note: these guides describe how to ENABLE Secure Boot - the location of the setting is the same, you just want to set it to Disabled instead of Enabled.

Still stuck?
If you've tried everything and Secure Boot is still showing as On, open a ticket with your motherboard model and Windows version.
