How do I disable UEFI Secure Boot?

info-symbol
UEFI Secure Boot (Unified Extensible Firmware Interface) is the successor of BIOS (Basic Input Output System) and is used in new 64-bit complete computers with Windows 8 and above.

The standard enabled UEFI runs only signed bootloaders for security reason. Therefore, it is not possible to boot the computer from a CD or USB drive, unless the option is disabled.


Note
Due to the fact that the existing GPT partitions require mandatory UEFI, Windows x64 may not boot after disabling secure boot.
