How to Disable Secure Boot in BIOS/UEFI

Step 1: Restart Your Computer
Start by restarting your computer. Ensure you are ready to press the necessary keys to enter the BIOS/UEFI settings immediately after the restart.

Step 2: Enter BIOS/UEFI Settings
As soon as your computer begins to restart, repeatedly press the key specific to your motherboard to enter the BIOS/UEFI settings. This key could be F2, Del, F10, or Esc. The correct key is usually displayed on the screen during the initial boot process.

Step 3: Navigate to Boot or Security Settings
Once you’re inside the BIOS/UEFI menu, use the arrow keys to navigate to the ‘Boot’ or ‘Security’ tab. This is where you’ll typically find options related to system boot settings and security features.

Step 4: Locate the Secure Boot Option
In the ‘Boot’ or ‘Security’ tab, look for a setting labeled ‘Secure Boot’. It might be under a sub-menu, so check any advanced settings if you don’t see it immediately.

Step 5: Disable Secure Boot
Select the ‘Secure Boot’ option using the arrow keys and press Enter. Change its setting to ‘Disabled’ or ‘Off’. This action will turn off the Secure Boot feature, allowing your computer to boot from unsigned or non-trusted sources.

Step 6: Save Changes and Exit
After disabling Secure Boot, navigate to the ‘Save & Exit’ menu or press the appropriate key (often F10) to save your changes. Confirm that you want to save and exit the BIOS/UEFI settings.

Step 7: Restart Your Computer
Your computer will automatically restart. With Secure Boot disabled, your system will now be able to boot from any compatible drive or operating system, including those that require non-traditional boot paths.
