UEFI replaces BIOS in Windows 8

UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs is designed to replace BIOS (Basic Input/Output System). It is designed to improve software interoperability and address limitations of BIOS. Some advantages of UEFI firmware include:

 

  • Better security by helping to protect the pre-startup—or pre-boot—process against bootkit attacks.
  • Faster startup times and resuming from hibernation.
  • Support for drives larger than 2.2 terabytes (TB).
  • Support for modern, 64-bit firmware device drivers that the system can use to address more than 17.2 billion gigabytes (GB) of memory during startup.
  • Capabililty to use BIOS with UEFI hardware.

NOTE: All 64-bit versions of PCs running Windows certified by the Windows Certification Program will use UEFI instead of BIOS.
