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. Available on Itanium-based computers only. [24]
The EFI System partition holds a filesystem and files used by the UEFI, while the BIOS boot partition is used in BIOS-based systems and accessed without a filesystem by holding raw binary code. The size requirements for a BIOS boot partition are quite low so it can be as small as about 30 KiB; however, as future boot loaders might require more ...
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.
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 partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
KDE Partition Manager is a disk partitioning application originally written by Volker Lanz for the KDE Platform.It was first released for KDE SC 4.1 and is released independently of the central KDE release cycle.
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.
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.
