WHAT IS THE SECURE BOOT?
Secure Boot or secure boot is a mode that Windows brings, and that prevents the execution of any unsigned or certified software at system startup. This is intended to prevent malware or unreliable applications from loading when you start your computer.
However, sometimes it is necessary to disable it to install certain hardware drivers, run older operating systems, or boot from USB devices.
