Hands-on Booting Summary

Hands-on Booting: Learn the Boot Process of Linux, Windows, and Unix by Yogesh Babar

Master the booting procedure of various operating systems with in-depth analysis of bootloaders and firmware. The primary focus is on the Linux booting procedure along with other popular operating systems such as Windows and Unix.

Hands-on Booting begins by explaining what a bootloader is, starting with the Linux bootloader followed by bootloaders for Windows and Unix systems. Next, you'll address the BIOS and UEFI firmware by installing multiple operating systems on one machine and booting them through the Linux bootloader. Further, you'll see the kernel's role in the booting procedure of the operating system and the dependency between kernel, initramfs, and dracut. You'll also cover systemd, examining its structure and how it mounts the user root filesystem. In the final section, the book explains troubleshooting methodologies such as debugging shells followed by live images and rescue mode.

On completing this book, you will understand the booting process of major operating systems such as Linux, Windows, and Unix. You will also know how to fix the Linux booting issues through various boot modes.

What You Will Learn

Examine the BIOS and UEFI firmware
Understanding the Linux boot loader (GRUB)
Work with initramfs, dracut, and systemd
Fix can't-boot issues on Linux

Who This Book Is For

Linux users, administrators, and developers.

Chapter 1: IntroductionChapter Goal: Why should we learn booting? Why is it important? No of pages : 2Sub -Topics1. Why booting? 2. What booting really is? 3. What happens when you start your computer4. Supply goes to CPU
Chapter 2: Multi-BootChapter Goal: First stage of booting is firmware and boot loader. There are different firmware's and every OS vendor has their own boot loader. To make readers understand it better, in this chapter we will install different operating systems (windows, Linux, Unix etc.) on one machine and would boot them through Linux boot loader. No of pages: 75 pagesSub - Topics 1. BIOS firmware2. Creating partition layout3. Installation sequence of different operating systems: a) Windows XP b) Solaris 2008 c) PC-BSD 9.0 d) Windows server 2k3 e) Windows seven f) Fedora 15 g) Red Hat Enterprise Linux 74. Booting sequence of every operating system. 5. Multi booting every operating system through Linux bootloader GRUB & through windows boot loaders (NTLDR / BCD) 6. UEFI firmwarea. Why UEFI when we already have BIOS? b. Advantages of UEFI7. Creating GPT partition table8. Installation sequence of latest operating systems: a. Oracle Solaris 11b. Windows 10c. Fedora 31d. Red Hat Enterprise Linux 89. Booting sequence and flowchart of each and every OS. 10. The 100 operating systems booting through one boot loader project.
Chapter 3: GRUB BootloaderChapter Goal: This topic will cover the GRUB bootloader in much depth. No of pages : 40 pages. Sub - Topics: 1.What is new in GRUB version 2? and why do we need it? 2.GRUB 2's structure on BIOS based system. 3. GRUB 2's structure on UEFI based system.4. Manual booting with GRUB 2.5. UEFI shell in detail.6. How to fix the corrupted GRUB.7. Some can't boot scenarios (related to bootloader) and how to fix them.8. Secure Boot 1. What is secure boot? 2. Linux and secure boot? 3. Shim bootloader of Ubuntu. 4. How to add new keys to UEFI? 5. How to sign kernel modules?
Chapter 4: KernelChapter Goal: This chapter covers the kernel's role in operating system's booting sequence. No of pages: 15Sub - Topics: 1. The kernel (vmlinuz) as an image file. 2. Who and how vmlinuz file is extracted? 3. Kernel will start the first process of Linux which is Systemd.
Chapter 5: InitramfsChapter Goal: In order to understand the rest of booting sequence we need to understand the basics of initramfs, and why we need initramfs ? No of pages: 15Sub - Topics: 1. Why Initramfs? 2. Structure of Initramfs. 3. How kernel extracts the initramfs in memory?4. How kernel mounts the initramfs as root?
Chapter 6: DracutChapter Goal: Dracut is a tool which generates the initramfs. Initramfs is responsible for loading the appropriate modules which are necessary for successful booting. No of pages: Around 17Sub - Topics: 1. How dracut makes initramfs image?2. How dracut choose modules to add in initramfs?3. How to customize the initramfs?4. Dracut command line options.5. How to blacklist or add modules in initramfs?
Chapter 7: SystemdChapter Goal: The systemd process (first process of Linux) will be launched from initramfs. Once it launched its purpose is to mount the root filesystem and switch to it. No of pages: 55Sub - Topics: 1. Structure of systemd.2. How does systemd reduces boot time?3. Booting flow of systemd inside initramfs.4. Plymouth5. Switching to new root filesystem.
Chapter 8: Debugging ShellsChapter Goal: Systemd provide various shells to debug the cant boot issues. This topic will cover the booting flow to reach to these shells as well as how to use these shells to fix the cant boot issues. No of pages: 35Sub - Topics: 1. Various dracut shells inside initramfs. 2. Emergency shell.3. The default Rescue mode.4. Flowchart of so far booting sequence.
Chapter 9: Live ImagesChapter Goal: The chapter will cover how does Live images of Operating System boots. No of pages: 4Sub-Topics: 1. Filesystem used inside Live images.2. How does the live images boot.
Chapter 10: Rescue ModeChapter Goal: Rescue mode plays a vital role in fixing the cant boot issues. No of pages: 15.
