Unlike the legacy PC BIOS, UEFI does not rely on boot sectors, defining instead a boot manager as part of the UEFI specification. When a computer is powered on, the boot manager checks the boot configuration and, based on its settings, then executes the specified OS boot loader or operating system kernel (usually boot loader [ 62 ] ).
In the UEFI Shell, the SmbiosView command can retrieve and display the SMBIOS data. [15] [16] One can often enter the UEFI shell by entering the system firmware settings, and then selecting the shell as a boot option (as opposed to a DVD drive or hard drive).
GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
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.
rEFInd, a boot manager for UEFI systems. coreboot is a free implementation of the UEFI or BIOS and usually deployed with the system board, and field upgrades provided by the vendor if need be. Parts of coreboot becomes the systems BIOS and stays resident in memory after boot. Das U-Boot is a bootloader for embedded systems. It is used on ...
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.
The Windows Boot Manager (BOOTMGR) is the bootloader provided by Microsoft for Windows NT versions starting with Windows Vista and Windows Server 2008.It is the first program launched by the BIOS or UEFI of the computer and is responsible for loading the rest of Windows. [1]
EasyBCD has a number of bootloader-related features that can be used to repair and configure the bootloader. From the "Manage Bootloader" section of EasyBCD, it is possible to switch between the BOOTMGR bootloader (used since Windows Vista) and the NTLDR bootloader (used by legacy versions of Windows, from Windows NT to Windows XP) in the MBR from within Windows by simply clicking a button.
