An example of a computer with one operating system per storage device is a dual-booting computer that stores Windows on one disk drive and Linux on another disk drive. In this case a multi-booting boot loader is not strictly necessary because the user can choose to enter BIOS configuration immediately after power-up and make the desired drive ...
Note: The column MBR (Master Boot Record) refers to whether or not the boot loader can be stored in the first sector of a mass storage device. The column VBR (Volume Boot Record) refers to the ability of the boot loader to be stored in the first sector of any partition on a mass storage device.
The Multiboot specification is an open standard describing how a boot loader can load an x86 operating system kernel. [1] [2] The specification allows any compliant boot-loader implementation to boot any compliant operating-system kernel. Thus, it allows different operating systems and boot loaders to work together and interoperate, without the ...

MS-DOS, Windows 3.x and Windows 9x can be chainloaded via modified versions of IO.sys and the Windows 9x boot sector. Linux and BSD are loaded either by handing off control of the boot process to GRUB or LILO or by using EasyBCD's own NeoGrub module (which is based on GRUB4DOS). Mac OS X is loaded via the Darwin bootloader.
LILO (Linux Loader) is a bootloader for Linux and was the default boot loader for most Linux distributions [when? Unlike loadlin , it allowed booting Linux without having DOS on the computer. [ 3 ] As of 2009, most distributions have switched to GRUB as the default boot loader. [ 4 ]
systemd-boot is a free and open-source boot manager created by obsoleting the gummiboot project and merging it into systemd in May 2015. [1] [2] [3] [4]gummiboot was developed by the Red Hat employees Kay Sievers and Harald Hoyer and designed as a minimal alternative to GNU GRUB for systems using the Unified Extensible Firmware Interface (UEFI).
