What Is Secure Boot & How It Works

Secure Boot is a safety feature developed by PC manufacturers to boot computers only with trusted software. It was initially introduced in Windows 8, followed by all the latest versions.

The fundamental purpose of a secure boot is to protect your computer from all types of malware. During secure boot, when a system restarts, the firmware examines the signatures of each part of the boot software (firmware drivers, operating system, EFI Application, etc.). If the signatures are satisfactory, the firmware controls the operating system, and the computer reboots.

What Happens If I Enable/Disable Secure Boot

Since the Secure Boot is a protection mechanism, enabling a Secure Boot keeps your PC safe from all malware attacks. Some malware packs load as soon as you start your PC. They are called Rootkits. Rootkits can save passwords, login details, and keystrokes, transfer sensitive files, and capture cryptographic data. For data security, optimal speed, and smooth operation, it is vital to enable the secure boot.

However, if you want to use previous Windows, certain graphic cards, and unauthorized software, the secure boot should be disabled. After disabling secure boot, the PC doesn't check the digital signature of the operating system. So, you can perform the following actions:

  • Booting Windows with an external hard drive or USB.
  • Dual Booting like Windows with Linux or Fedora.
  • Booting with Windows password recovery tools.
  • Operating previous Windows Versions.

In short, enabling and disabling secure boot depends upon your requirement. If you want maximum security, you should allow it to. If you wish to use extravagant third-party apps, you can disable Secure Boot.

How to Enable/Disable Secure Boot on your Computer

So far, we have explained what Secure Boot is and what happens when you enable/disable it. This section presents a step-by-step guide to enable/disable secure boot on your computer.

How to Enable Secure Boot

Before enabling Secure Boot, ensure your system has a Windows 8 or above operating system, the latest UFI, and necessary firmware options.

After that, follow these steps to enable Secure Boot on your PC.

Step 1. Remove operating systems, software, and graphic cards incompatible with Secure Boot.

Step 2. Go to the PC BIOS Menu. For that, Press and hold the shift key and select "Restart." After that, go to Troubleshoot > Advanced Options.

Step 5. Exit the menu after saving these changes. You can now boot to any media supporting secure boot. You can also install a new operating system. However, the Windows partition storage type will be GPT Partitions instead of mbr.

Step 6. After installing the operating system, you can cross-check the enabling of Secure Boot. To do that, type "msinfo32.exe" in the open box and check the status of the Secure Boot state. It says "On," which means the Secure Boot is enabled.

How to Disable Secure Boot

If your PC doesn't allow third-party software, that means Secure Boot mode is functional. You can follow these steps to disable it.

Step 1. Before disabling, check the latest updates of the Secure Boot system. It will show an updated list of software, graphic cards, etc., compatible with your computer. This will let you know whether disabling is required or not.

Step 2. Once again, open the BIOS Menu. From Windows, hold the Shift key while selecting Restart. Go to Troubleshoot > Advanced Options.

The Bottom Line

SecureBoot is an advanced security feature that works as a wall against malware. It helps improve the speed, performance, and efficiency of your PC. The system works for Windows 8 or above. However, when you need to run previous Windows or unauthorized apps and graphic cards, you must disable them.

This article provides a step-by-step guide on how to enable and disable Secure Boot. So that you can use the feature as per your requirement, give it a read and let us know your views about this software.


1. What is the disadvantage of Secure Boot?

Since Secure Boot is only compatible with Windows 8 or above, you can't use previous Windows versions with this. Plus, it blocks unlicensed software, which sometimes is required to get the job done. It also stops the system from accepting certain graphic cards, which can hinder running professional software and games.

2. Is Secure Boot UEFI or legacy?

Secure boot only supports the operating system with the latest UFI native boot. The legacy boot is a fundamental input/output system (BIOS) firmware. It doesn't support a Secure Boot.

3. Does Windows 10 require UEFI Secure Boot?

Microsoft wants PC Manufacturers to enable Secure Boot in the latest systems if they want an official Windows sticker and certification. However, old systems can upgrade to Windows 10 without UEFI Secure Boot.

4. Is Secure Boot mandatory?

Nope, it's a choice. You can enable or disable it as per your requirement. The operating system will work fine without it.
