About UEFI and the Startup Menu

  • PrintPrint

UEFI overview

Unified Extensible Firmware Interface (UEFI) is firmware code from a chip on your motherboard that provides extra functionality, beyond the Basic Input/Output System (BIOS). UEFI is a way to do things with your computer before an operating system is loaded. To name a few features, UEFI can provide extra graphic menus and system information on a computer, and basic diagnostics on both a computer and a tablet. How does it do this? UEFI works with the BIOS to initialize the computer or tablet's hardware before handing hardware control over to the operating system. UEFI can also load and display software programs from storage devices to provide even more functionality, such as more detailed system information and extended hardware diagnostics.

Frequently Asked Questions about UEFI

Click a question below to find an answer to a frequently asked question about UEFI.
Secure Boot is a feature that is enabled by the Unified Extensible Firmware Interface (UEFI) that prevents the loading of unauthorized operating systems and software after the computer is powered on. It is a major defense against a security threat called root kits.
For more information about Secure Boot, see the HP Support document Secure Boot (Windows 8) .
Both BIOS and UEFI are firmware code stored on chips on the motherboard.
The Basic Input/Output System (BIOS) is responsible for setting up devices used by your system so that those devices can send and receive data. The BIOS has a limited amount of memory as well as other design constraints that limit what you can do with your computer before the operating system loads.
Unified Extensible Firmware Interface (UEFI) works with the BIOS and as an extension to the BIOS, to allow more functionality than what the BIOS alone is able to provide. UEFI provides more graphical menus, more detailed diagnostics, and allows the BIOS to contain more rich features, such as Secure Boot. UEFI can also open EFI compatible software from other storage locations, such as a hard drive or a USB storage device, for even more functionality.
The Extensible Firmware Interface (EFI) was originally developed by Intel. In 2005, the Unified EFI Forum was created. The United EFI Forum manages the Unified Extensible Firmware Interface (UEFI) specification. All of the EFI specifications developed by Intel are labeled version 1.x. UEFI specifications start at version 2.0.
