Four of the best Linux boot programs

Four of the best Linux boot programs
GuideWhen you enable your machine and the POST is successful, the BIOS (Basic Input and Output System) immediately locates the configured boot media and starts from MBR (Master Boot Record) or a GUID (globally unique identifier) partitioned table reads some commands, which is the first 512 bytes of content in the boot media. The Master Boot Record (MBR) contains two important sets of information. The first is the boot program, and the second is the partition table.What is a Bootstrap program?

Bootstrap programIt is a small program stored in the MBR (primary Boot Record) or GUID (globally unique identifier) partition table to help load the operating system to the memory. If you do not have a boot program, your operating system will not be able to load it into the memory.

There are some boot programs that we can install on the system along with Linux. In this article, I will briefly talk about several of the best Linux boot programs that can work with Linux.

Excellent boot program1. GNU GRUB

Gnu grub is a very popular and probably the most popular Linux boot program with multiple boot capabilities. It was invented by the original Eirch Stefan Broleyn (Overall guidance program. Gnu grub enhances the original GRUB and brings some improvements, new features, and vulnerability fixes.

Importantly, GRUB 2 has now replaced GRUB. It is worth noting that the name GRUB is renamed GRUB Legacy, but it is not actively developed. However, it can be used to guide the old system because the vulnerability fix continues.

GRUB has the following notable features:

1. Support for multiple Guidance
2. Supports multiple hardware structures and operating systems, such as Linux and Windows
3. Provides a Bash-like interactive command line interface, allowing you to run the GRUB command to interact with the configuration file.
4. Allow access to the GRUB Editor
5. Supports setting encryption passwords to ensure security
6. Provides guidance from the network and secondary features.

2. LILO

LILO (Linux boot program) Is a simple but powerful and extremely stable Linux boot program. Since GRUB has greatly improved and added many powerful features, it is becoming more and more popular. Therefore, LILO is not very popular among Linux users.

During LILO boot, the word "LILO" appears on the screen, and each letter appears before and after a specific event. However, since December 2015, LILO's development has stopped. It has many features, such as the following:

1. Interactive command line interface not provided
2. Support for some error codes
3. Network boot is not supported (LCTT: ELILO variants support TFTP/DHCP boot)
4. All files are stored on the first 1024 cylinders of the driver.
5. Restrictions on BTFS, GTPs, and RAID

3. BURG-new boot program

Based on GRUB, BURG is a relatively new boot program (Development was stopped in 2011 ). Since BURG originated from GRUB, it has some major GRUB features. Even so, BURG also provides some outstanding features, such as a new object format that supports multiple platforms including Linux, Windows, Mac OS, and FreeBSD.

In addition, BURG supports highly configurable text and icon-mode boot menus, and the "stream" to be added will support different input/output devices to work together in the future.

4. Syslinux

Syslinux is a lightweight boot program that can be guided from a CD drive or network. Syslinux supports file systems such as FAT on MS-DOS, ext2 on Linux, ext3, and ext4. Syslinux also supports Btrfs on a single uncompressed device.

Note that because Syslinux can only access files in its own partition, it does not have the ability to boot multiple file systems.

Conclusion

A Bootstrap program allows you to manage multiple operating systems on your machine and select one of them at a certain time. Without a boot program, your machine cannot load the kernel and the rest of the operating system.
