Dual Booting Windows 8 and Ubuntu UEFI using Rufus

What is UEFI?

Short for Unified Extensible Firmware Interface, UEFI is a specification that defines a more modernized model for the interface between computer operating systems and platform firmware during the boot, or start-up, process.

The UEFI specification offers advanced features over BIOS such as secure boot, low-level cryptography, network authentication and universal graphics drivers. The Secure Boot functionality in UEFI provides the basis for the Microsoft Secure Boot feature in Windows 8 that enables the OS to detect rootkits and similar malware attacks.

What is Rufus?

Rufus is a utility that helps format and create bootable USB flash drives, such as USB drives, memory sticks etc.

It can be particularly valuable for situations where:

• You have to make USB installations media from bootable ISO’s (Windows, Linux, UEFI, etc.) 
• You have to deal with a system that doesn't have an OS installed
• You have to flash a BIOS or other firmware from DOS 
• You need to run a low-level utility

Users can download Rufus from here.
