GNU-EFI and TianoCore are supported as main development platforms for writing binary UEFI applications in C to launch right from the rEFInd GUI menu. Typical purposes of an EFI application are fixing boot problems and programmatically modifying settings within UEFI environment, which would otherwise be performed from within the BIOS of a personal computer (PC) without UEFI.
UEFI support in Windows began in 2008 with Windows Vista SP1. [22] The Windows boot manager is located at the \EFI\Microsoft\Boot\ subfolder of the EFI system partition. [23] On Windows XP 64-Bit Edition and later, access to the EFI system partition is obtained by running the mountvol command. Mounts the EFI system partition on the specified drive.
fwupd is an open-source daemon for managing the installation of firmware updates on Linux-based systems, developed by GNOME maintainer Richard Hughes. [1] It is designed primarily for servicing the Unified Extensible Firmware Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel 4.2 and later.
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project.GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular ...
If UEFI Secure Boot is supported, a "shim" or "Preloader" is often booted by the UEFI before the bootloader or EFI-stub-bearing kernel. [11] Even if UEFI Secure Boot is disabled this may be present and booted in case it is later enabled. It merely acts to add an extra signing key database providing keys for signature verification of subsequent ...
rEFIt is a boot menu and maintenance toolkit for EFI-based machines like the Intel Macs. It can be used to boot multiple operating systems, including triple-boot setups with software such as Apple's Boot Camp Assistant. It also provides a way to enter and explore the EFI pre-boot environment. [6]
The CD can also boot from a customized DVD which has almost 4.6 GB of free space for backed-up files. This makes it good for storing all the information that is needed from a hard drive and then formatting it. To burn the DVD, one must burn the image file first and then add all the separate files and folders. [9]
The distribution Ubuntu added support for UEFI Secure Boot as of version 12.10. [121] Furthermore, the Linux kernel can be compiled with the option to run as an EFI bootloader on its own through the EFI boot stub feature. HP-UX has used (U)EFI as its boot mechanism on IA-64 systems since 2002.
