Explanation
Secure Boot is a feature of UEFI (Unified Extensible Firmware Interface) that prevents unauthorized software from running during the boot process. Secure Boot verifies the digital signature of the boot loader and the operating system, and only allows them to run if they are signed by a trusted authority. However, Secure Boot can also prevent some legitimate software, such as firmware updates, from running if they are not signed or recognized by the system. Therefore, the technician may need to disable Secure Boot in order to install a firmware update for the system board UEFI from a USB key.
