A MBR program may interact with the user to determine which partition on which drive should boot, and may transfer control to the MBR of a different drive. Other MBR code contains a list of disk locations (often corresponding to the contents of files in a filesystem) of the remainder of the boot manager code to load and to execute. (The first ...
On Apple Mac computers using Intel x86-64 processor architecture, the EFI system partition is initially left blank and unused for booting into macOS. [13] [14]However, the EFI system partition is used as a staging area for firmware updates [15] and for the Microsoft Windows bootloader for Mac computers configured to boot into a Windows partition using Boot Camp.
Accesses the file system on the boot drive (either FAT or New Technology File System, NTFS). If Windows was put in the hibernation state, the contents of hiberfil.sys are loaded into memory and the system resumes where it left off. Otherwise, reads boot.ini and prompts the user with the boot menu accordingly. If a non NT-based OS is selected ...
Rufus was originally designed [5] as a modern open source replacement for the HP USB Disk Storage Format Tool for Windows, [6] which was primarily used to create DOS bootable USB flash drives. The first official release of Rufus, version 1.0.3 (earlier versions were internal/alpha only [ 7 ] ), was released on December 04, 2011, with originally ...
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 ...
The UEFI (not legacy boot via CSM) does not rely on boot sectors, UEFI system loads the boot loader (EFI application file in USB disk or in the EFI system partition) directly. [1] Additionally, the UEFI specification also contains "secure boot", which basically wants the UEFI code to be digitally signed .
A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

This four-piece scheme allowed developers to dynamically add a new bootable filesystem, as the ext2 driver for OS/2 demonstrated. CD-ROM filesystem driver was added in OS/2 2.0, UDF was added in OS/2 4.0 and JFS was added in OS/2 4.5. ArcaOS, the latest packaging of OS/2, has a number of filesystem drivers available, including FAT32. [1]
