UEFI is used together with GPT hard drive generally. As everybody knows, compared with the familiar MBR, the GPT hard drive partition framework has lots of outstanding advantages. For instance, the hard drive using GPT partition framework can support volume as large as 18 EB (MBR only supports volume within 2TB), and the GPT doesn’t limit partition quantity (MBR supports at most four primary partitions). However, since the traditional BIOS has certain limitations, users can’t experience advantages of GPT partition framework under BIOS system, let alone boot Windows operating system through GPT system partition. As the replacer of traditional BIOS, UEFI is favored by computer manufacturers and users because of the features such as powerful expansibility, compatibility and easy-to-use operation. Along with the popularity of Windows 8, UEFI gradually own more users.
