What does uefi hard disk mean?

uefi hard disk means UEFI hard disk.

Unified Extensible Firmware Interface (UEFI) is a personal computer system specification that defines the software interface between the operating system and system firmware as an alternative to BIOS. The extensible firmware interface is responsible for power-on self-test (POST), contacting the operating system, and providing an interface between the operating system and the hardware.

UEFI was formerly the Intel Boot Initiative developed by Intel in 1998 and was later renamed Extensible Firmware Interface (EFI). Intel handed it over to the Unified Extensible Firmware Interface Forum (Unified EFI Forum) for promotion and development in 2005. To highlight this, EFI was also renamed UEFI (Unified EFI). The founders of the UEFI Forum are 11 well-known computer companies, including hardware manufacturers such as Intel and IBM, software manufacturer Microsoft, and BIOS manufacturers AMI, Insyde and Phoenix.

● Pre-EFI initialization module
