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.
EasyBCD 2.3 introduced additional support for creating and managing entries for UEFI-based Windows entries in the boot menu. [2] As of June 20, 2011 with the release of EasyBCD 2.1, it is no longer free for use in commercial environments which require the purchase of a paid license, however it remains free for home and non-profit use without ...

Since Windows NT 3.1 (the first version of Windows NT), [4] Microsoft has defined the terms as follows: The system partition (or system volume) [5] is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. [6]: 1087 This partition holds the boot sector and is marked active. [7]: 970
After over 100 people were killed in a South Korea plane accident, here are the worst accidents and crashes in aviation history.
In UEFI systems, the Linux kernel can be executed directly by UEFI firmware via the EFI boot stub, [8] but usually uses GRUB 2 or systemd-boot as a bootloader. [ 9 ] [ 10 ] 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 ]
The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting.
