What is Secure Boot?

Secure Boot protects the boot process against security attacks from malicious code like malware and ransomware. Secure Boot is firmware-dependent and requires that the computer BIOS is set to UEFI mode. The Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots).  Most modern PCs are capable of Secure Boot, but in some instances, there may be settings that cause the PC to appear to not be capable of Secure Boot. These settings can be changed in the PC firmware. Firmware, often called BIOS (Basic Input/Output System), is the software that starts up before Windows when you first turn on your PC. 

The process of changing the BIOS settings are the same or with little differences on various manufacturer PCs. You can check the article about “All Laptops And Desktops System BIOS Boot Keys“.
