Learn how to enable secure boot on UEFI BIOS to enhance your computer’s security and protect your system
In today’s increasingly digital world, ensuring the security of your computer is more important than ever. With the growing prevalence of cyberattacks, it’s essential to adopt proactive security measures. One such measure is enabling Secure Boot on your computer’s UEFI BIOS (Unified Extensible Firmware Interface Basic Input/Output System). Secure Boot helps protect your system from malware and unauthorized software, especially during the boot process, which is a critical stage in your system’s startup sequence. In this article, we will guide you through how to enable Secure Boot on UEFI BIOS to enhance your computer’s security and protect your system from potential threats.
What is Secure Boot and UEFI BIOS?
Before diving into how to enable Secure Boot, it is crucial to understand what Secure Boot and UEFI BIOS are and how they contribute to your computer’s overall security.
UEFI BIOS is a modern version of the traditional BIOS that governs how your computer starts up. It is the first software your computer runs when you power it on and is responsible for initializing your hardware components before booting your operating system (OS). UEFI is faster, more feature-rich, and offers advanced security options compared to legacy BIOS.
Secure Boot is one of these advanced security features offered by UEFI BIOS. It ensures that your system boots only using software that is trusted by the Original Equipment Manufacturer (OEM). This means it verifies that the bootloader and operating system kernel have not been tampered with by malware or unauthorized software. If the system detects any discrepancies, it will block the boot process and prevent the system from running potentially harmful software.
The Importance of Secure Boot for Computer Security
Enabling Secure Boot offers numerous benefits for computer security, including:
- Prevention of Rootkits and Bootkits: Secure Boot prevents malware from loading during the boot process, effectively defending against rootkits and bootkits—malicious software that infects the system before the OS starts.
- Protection Against OS Corruption: It ensures that only legitimate, signed operating systems and bootloaders are allowed to load, minimizing the risk of OS corruption.
- Enhanced Data Integrity: By ensuring that no unauthorized code runs during boot, Secure Boot adds an extra layer of protection to your system’s data integrity.
- Trusted Hardware Initialization: It ensures that all firmware and hardware components of the computer are initialized correctly and securely.
How to Enable Secure Boot on UEFI BIOS
Now that we understand the significance of Secure Boot, let’s go through the step-by-step process of enabling Secure Boot on a computer with UEFI BIOS.
Step 1: Access the UEFI BIOS
To enable Secure Boot, you must first access your system’s UEFI BIOS settings. Follow these steps:
- Restart your computer: Begin by restarting your PC or turning it on if it’s off.
- Enter UEFI BIOS: As soon as your computer begins to boot up, press the appropriate key to enter the BIOS settings. Common keys are F2, Del, Esc, or F10, but this may vary depending on your system’s manufacturer.
- Wait for the BIOS screen: Once you press the key, you will be directed to the UEFI BIOS menu.
Step 2: Locate the Secure Boot Option
In the UEFI BIOS menu, you will need to find the Secure Boot settings. These settings are usually located under the “Security,” “Boot,” or “Authentication” tab, depending on your system’s manufacturer.
Here’s how to find it:
- Navigate to the Boot tab or the Security tab using the arrow keys.
- Look for the option labeled Secure Boot. It may also be labeled as Secure Boot Control or something similar.
Step 3: Enable Secure Boot
Once you’ve located the Secure Boot option, follow these steps to enable it:
- Select the Secure Boot option: Use the arrow keys to highlight the Secure Boot setting.
- Change the setting: Typically, the Secure Boot setting is set to Disabled by default. Use the +/- keys or the Enter key to change the setting to Enabled.
- Save and exit: After enabling Secure Boot, save your changes and exit the BIOS. You can usually do this by pressing F10 or selecting “Save and Exit” from the BIOS menu.
Step 4: Reboot Your System
Your system will reboot, and Secure Boot will be enabled during the boot process. You may see a prompt indicating that Secure Boot is active. The system will now only boot with trusted software, further enhancing the security of your system.
Troubleshooting Secure Boot Issues
While enabling Secure Boot can significantly improve your system’s security, it can sometimes lead to issues. Below are some common troubleshooting tips for resolving Secure Boot-related problems:
1. Compatibility Issues with Operating Systems
If you are running an older operating system or a non-signed OS (such as some Linux distributions), you may encounter boot problems after enabling Secure Boot. In this case, try the following:
- Ensure your OS supports Secure Boot. Most modern versions of Windows (8 and later) and popular Linux distributions (e.g., Ubuntu) are compatible with Secure Boot.
- If your OS is not signed, consider disabling Secure Boot temporarily to install the OS and then re-enable it once the installation is complete.
2. Secure Boot Disabled After Update
In some cases, a BIOS update or system firmware update may reset the Secure Boot setting. If this happens, simply follow the steps to enable Secure Boot again. You can also check the system manufacturer’s website for firmware updates or additional support if the issue persists.
3. Incorrect Boot Order
If you are unable to boot after enabling Secure Boot, it could be due to an incorrect boot order. Make sure your primary storage device (e.g., SSD or HDD with the OS installed) is set as the first boot option in the UEFI BIOS.
Other Security Measures to Complement Secure Boot
While enabling Secure Boot is a great first step, it is essential to combine it with other security measures to ensure your system is fully protected. Consider the following:
- Keep your system updated: Regularly install software updates, including firmware, drivers, and OS updates to patch security vulnerabilities.
- Enable Full Disk Encryption (FDE): Use encryption tools like BitLocker (for Windows) or FileVault (for macOS) to encrypt your hard drive, ensuring your data remains secure even if your device is lost or stolen.
- Use a Trusted Antivirus: Ensure that you have a reputable antivirus program running to protect against malware, ransomware, and other threats.

Conclusion
Learning how to enable secure boot on UEFI BIOS to enhance your computer’s security and protect your system is a crucial step in securing your device. By preventing unauthorized software from loading during the boot process, Secure Boot helps safeguard your system from malware, rootkits, and other malicious threats that could compromise your data and integrity. Following the steps outlined in this guide will help you enable this important security feature and keep your system protected. Don’t forget to combine Secure Boot with other security practices like software updates, encryption, and antivirus protection to ensure comprehensive security.
