In legacy BIOS compatibility mode the UEFI firmware functions as a standard BIOS instead of UEFI firmware, which improves compatibility with operating systems that weren't designed with UEFI in mind.
Enter the BIOS/UEFI setup utility when the computer is starting, disable Secure Boot, and enable Legacy/CSM boot mode.
disable Secure Boot
enable Legacy/CSM boot mode
