Unified Extensive Firmware Interface(UEFI) is set of specifications that allow interaction between components of both software and hardware of a system. It usually operates between an operating system and a firmware. This interface is meant to replace the BIOS(Basic Input and Output Setup). It is commonly becoming a house-hood name in new generation computers since its development.
You can not ignore the fact that it prevents a user from installing other Operating Systems or different version of the same Operating System in a computer due to the fact that it doesn't use Operating System or Multi-boot system from the BIOS. It supports booting by reading partition table and filesystems. That makes most Operating System developers to use it to make a system boot to a particular OS(Operating System). It also makes your system to be more secured against malicious software that might be detrimental to the whole operations.
There is a way to get around it if you are willing to install other OS or trying to setup other version of the same Operating System.
