Secure Boot is a security feature of modern computers that helps prevent malicious software loading (malware) during startup.

Secure Boot ensures that only the software approved by the computer manufacturer can be charged at startup and prevents malware from being performed before the operating system is loaded, reducing the risk of virus.

Secure boot activation can be done from the BIOS or UEFi settings (firmware unit).

Microsoft has introduced this feature on the list of system requirements to be able to install and run the Windows 11 operating system.
