Secure Boot is a security feature in Windows that helps protect your PC from malware and other threats by ensuring that only authorized software is loaded during the boot process. However, there may be situations where you need to disable Secure Boot, such as when installing a new operating system or running a legacy application. In this article, we will walk you through the process of disabling Secure Boot in Windows, and provide you with the information you need to make an informed decision.
Understanding Secure Boot
Before we dive into the process of disabling Secure Boot, it’s essential to understand what it is and how it works. Secure Boot is a feature that was introduced in Windows 8 and is designed to prevent malware from loading during the boot process. It does this by checking the digital signature of the software that is loaded during boot, and only allowing software that has a valid signature to run.
Secure Boot uses a combination of hardware and software components to ensure that only authorized software is loaded. The hardware component is the UEFI (Unified Extensible Firmware Interface) firmware, which is the software that controls the PC’s hardware components. The software component is the operating system, which is responsible for loading the software that is required to boot the PC.
Types of Secure Boot
There are two types of Secure Boot: UEFI Secure Boot and Legacy Secure Boot. UEFI Secure Boot is the most common type and is used in most modern PCs. It uses the UEFI firmware to check the digital signature of the software that is loaded during boot. Legacy Secure Boot, on the other hand, uses the BIOS (Basic Input/Output System) firmware to check the digital signature of the software.
Secure Boot Modes
Secure Boot can operate in one of three modes: UEFI mode, Legacy mode, and UEFI with Compatibility Support Module (CSM) mode. UEFI mode is the most secure mode and is used in most modern PCs. Legacy mode is used in older PCs that do not support UEFI. UEFI with CSM mode is used in PCs that support both UEFI and Legacy modes.
