Secure Boot is a feature on UEFI- based clients that helps increase the security of a client by preventing unauthorized software from

running on a client during the boot sequence. It checks whether each software has a valid signature, including the operating system (OS)

that is being loaded during booting.

The thin client device comes enabled with UEFI and Secure Boot. Due to this feature, you cannot boot from USB keys unless you enter the

BIOS, disable Secure Boot, change the boot mode to Legacy, and enable the Boot from USB option.
