This article mainly shows you "what are the common boot procedures in Linux", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "what are the common boot procedures in Linux" this article.

Bootstrapping is a means often used by computers to start input. After the computer is started, a small amount of instructions and data are input by the device, and then they enter other programs. This process is called boot. The bootstrap program in the microcomputer can input the program and data entered by the user through the keyboard into the random access memory.

Excellent bootstrap program Syslinux

Syslinux is a lightweight boot program that can boot from CD-ROM drives, networks, etc. Syslinux supports file systems such as FAT on MS-DOS, ext2 on Linux, ext3, ext4, and so on. Syslinux also supports Btrfs on an uncompressed single device.

Note that because Syslinux can only access files on its own partition, it does not have multiple file system boot capabilities.

GNU GRUB

GNU GRUB is a very popular and probably the most widely used Linux bootstrap program with multiple boot capabilities, based on the GRUB (unified bootstrap) invented by the original Eirch Stefan Broleyn. GNU GRUB enhances the original GRUB with some improvements, new features, and bug fixes.

Importantly, GRUB 2 has now replaced GRUB. It is worth noting that the name GRUB has been renamed GRUB Legacy, but there is no active development, but it can be used to boot older systems as bug fixes continue.

GRUB has the following remarkable features:

Support for multi-boot support a variety of hardware structures and operating systems, such as Linux and Windows provide an interactive command line interface similar to Bash, so that users can run GRUB commands to interact with configuration files to allow access to the GRUB editor support for setting encrypted passwords to ensure security support for booting from the network, as well as some minor features

LILO

LILO (Linux bootstrapper) is a simple but powerful and very stable Linux bootstrapper. Because GRUB has greatly improved and added many powerful features, and is becoming more and more popular, LILO is no longer very popular among Linux users.

When LILO boots, the word "LILO" appears on the screen, and each letter appears before and after a particular event. However, since December 2015, development of LILO has stopped, and it has many features such as the following:

Does not provide interactive command line interface support some error codes do not support network boot (LCTT translation: its variant ELILO supports TFTP/DHCP boot) all files stored on the first 1024 cylinders of the driver are subject to restrictions such as BTFS, GTP, RAID, etc.

BURG-the new bootstrapper

Based on GRUB,BURG is a relatively new bootstrapper (development stopped in 2011). Because BURG originated from GRUB, it has some of the main features of GRUB. However, BURG also provides some excellent features, such as a new object format that can support multiple platforms, including Linux, Windows, Mac OS, FreeBSD, and so on.

In addition, BURG supports highly configurable text and icon mode boot menus, and the planned addition of "streams" supports the ability of different input / output devices to work together in the future.
