SYSLINUXThe Syslinux Project is a suite of five different boot loaders for starting up Linux distros on computers. It was primarily developed by H. Peter Anvin. The Syslinux Project consists of five different boot loaders: The eponymous SYSLINUX, used for booting from the filesystem ISOLINUX, used for booting from the ISO 9660 filesystem PXELINUX, used for booting from a network server using the Preboot Execution Environment (PXE) system EXTLINUX, used for booting from Btrfs, ext2, ext3, ext4, , NTFS, , and XFS filesystems MEMDISK, emulates a RAM disk for older operating systems like MS-DOS The project also includes two separate menu systems and a development environment for additional modules.
Multi-bootingMulti-booting is the act of installing multiple operating systems on a single computer, and being able to choose which one to boot. The term dual-booting refers to the common configuration of specifically two operating systems. Multi-booting may require a custom boot loader. Multi-booting allows more than one operating system to reside on one computer; for example, if a user has a primary operating system that they use most frequently and an alternate operating system that they use less frequently.
GNU GRUBGNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system's partitions. GNU GRUB was developed from a package called the Grand Unified Bootloader (a play on Grand Unified Theory).
