How To: Enter the system BIOS or UEFI in Windows 8
Access to the system BIOS will depend on Windows 8 installed on your computer.
If you upgraded to Windows 8 from Windows 7, then you will follow the instructions under UPGRADE.
If your computer came from the factory with Windows 8 installed, then follow the instructions under PREINSTALLED.
NOTE: On Windows 8 operating systems that came preinstalled on the laptop from the factory, the BIOS has been replaced by UEFI (Unified Extensible Firmware Interface).
