Boot process in Linux
Linux Booting Process Steps: 6 Stages of Linux Boot Process (Startup Sequence) Press the power button on your system, and after few moments you see the Linux login prompt MUSIC CREDITS :ON MY WAY KEVIN MACLEOD-IN COMPETECH.COM https://creativecommons.org/licenses/by/3.0/ ISRC: USUAN1600062 Have you ever wondered what happens behind the scenes from the time you press the power button until the Linux login prompt appears? The following are the 6 high level stages of a typical Linux boot process. 1. BIOS BIOS stands for Basic Input/Output System Performs some system integrity checks Searches, loads, and executes the boot loader program. It looks for boot loader in floppy, cd-rom, or hard drive. You can press a key (typically F12 of F2, but it depends on your system) during the BIOS startup to change the boot sequence. Once the boot loader program is detected and loaded into the memory, BIOS gives the control to it. So, in simple terms BIOS loads and executes the MBR boot loader. 2. MBR MBR stands for Master Boot Record. It is located in the 1st sector of the bootable disk. Typically /dev/hda, or /dev/sda MBR is less than 512 bytes in size. This has three components 1) primary boot loader info in 1st 446 bytes 2) partition table info in next 64 bytes 3) mbr validation check in last 2 bytes. It contains information about GRUB (or LILO in old systems). So, in simple terms MBR loads and executes the GRUB boot loader. 3. GRUB GRUB stands for Grand Unified Bootloader. If you have multiple kernel images installed on your system, you can choose which one to be executed. GRUB displays a splash screen, waits for few seconds, if you don’t enter anything, it loads the default kernel image as specified in the grub configuration file. GRUB has the knowledge of the filesystem (the older Linux loader LILO didn’t understand filesystem). Grub configuration file is /boot/grub/grub.conf (/etc/grub.conf is a link to this). The following is sample grub.conf of CentOS. #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-194.el5PAE) root (hd0,0) kernel /boot/vmlinuz-2.6.18-194.el5PAE ro root=LABEL=/ initrd /boot/initrd-2.6.18-194.el5PAE.img As you notice from the above info, it contains kernel and initrd image. So, in simple terms GRUB just loads and executes Kernel and initrd images. 4. Kernel Mounts the root file system as specified in the “root=” in grub.conf Kernel executes the /sbin/init program Since init was the 1st program to be executed by Linux Kernel, it has the process id (PID) of 1. Do a ‘ps -ef | grep init’ and check the pid. initrd stands for Initial RAM Disk. initrd is used by kernel as temporary root file system until kernel is booted and the real root file system is mounted. It also contains necessary drivers compiled inside, which helps it to access the hard drive partitions, and other hardware. 5. Init Looks at the /etc/inittab file to decide the Linux run level. Following are the available run levels 0 – halt 1 – Single user mode 2 – Multiuser, without NFS 3 – Full multiuser mode 4 – unused 5 – X11 6 – reboot Init identifies the default initlevel from /etc/inittab and uses that to load all appropriate program. Execute ‘grep initdefault /etc/inittab’ on your system to identify the default run level If you want to get into trouble, you can set the default run level to 0 or 6. Since you know what 0 and 6 means, probably you might not do that. Typically you would set the default run level to either 3 or 5. 6. Runlevel programs When the Linux system is booting up, you might see various services getting started. For example, it might say “starting sendmail …. OK”. Those are the runlevel programs, executed from the run level directory as defined by your run level. Depending on your default init level setting, the system will execute the programs from one of the following directories. Run level 0 – /etc/rc.d/rc0.d/ Run level 1 – /etc/rc.d/rc1.d/ Run level 2 – /etc/rc.d/rc2.d/ Run level 3 – /etc/rc.d/rc3.d/ Run level 4 – /etc/rc.d/rc4.d/ Run level 5 – /etc/rc.d/rc5.d/ Run level 6 – /etc/rc.d/rc6.d/ Please note that there are also symbolic links available for these directory under /etc directly. So, /etc/rc0.d is linked to /etc/rc.d/rc0.d. Under the /etc/rc.d/rc*.d/ directories, you would see programs that start with S and K. Programs starts with S are used during startup. S for startup. Programs starts with K are used during shutdown. K for kill. There are numbers right next to S and K in the program names. Those are the sequence number in which the programs should be started or killed. For example, S12syslog is to start the syslog deamon, which has the sequence number of 12. S80sendmail is to start the sendmail daemon, which has the sequence number of 80. So, syslog program will be started before sendmail. There you have it. That is what happens during the Linux boot process.

How to Restore and Customize Ubuntu GRUB Bootloader
GRUB bootloader gets overrided if you install Windows after Ubuntu. I make this video tutorial on how to restore and customize the GRUB loader. Common Problem: You install Windows after you install Ubuntu. That erases the GRUB loader, and instead of being able to switch between Ubuntu and Windows, Windows will boot automatically. Steps: 1) Create a bootable USB Flash Drive of Ubuntu. - Download Ubuntu http://www.ubuntu.com/download/desktop - Download and install Universal USB Installer http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/ - Create bootable USB flash drive of Ubuntu 2) Restart computer and boot into Ubuntu. 3) Use try Ubuntu and install boot-repair. Commands: sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install boot-repair y boot-repair 4) Recommended repair. 5) Afterwards, if you restart, you can see the GRUB Bootloader again. You can select between Ubuntu and Windows. 6) Use Ubuntu Next parts will be customizing Ubuntu GRUB Bootloader: 8) Open a terminal: sudo fdisk -l 9) Keep track of what sda number is Windows partition on. 10) Customize GRUB bootloader cd /boot/grub sudo gedit grub.cfg 11) Delete any duplicate entries that do not match sda number correctly, and delete any extra entries that you may never use.

Learning Linux : Lesson 5 GRUB Bootloader
More videos like this at http://www.theurbanpenguin.com This week we are are 5 weeks into the schedule and we take a look at the GRUB bootloader, or the Grand Unified Bootloader. Using openSUSE the configuration for this is /boot/grub/menu.lst. The bootloader allows us to select the OS and any kernel options. We can add entries into the menu and, should we wish, delete entries. We will also look at securing the GRUB menu with a password, this way you can only select from menu items and not append additional kernel options. The risk of this is highlighted by booting with the init=/bin/bash; this gives us root access with need of a password. Adding the grub password and encrypting it with grub-md5-crypt will prevent this.

Boot Directory Explained (also Linux boot process)
/boot is an important folder in Linux. /boot folder contains all the boot related info files and folders such as grub.conf, vmlinuz image aka kernel etc. /boot/initrd-2.6.18-194.17.1 img file: Initrd in other words called as Initializing RAM Disk which loads temporary file system in to RAM at the time of booting process before actual file system mounting. This file is loaded by your kernel image file at the time of booting. This initrd image knows only one configuration file /etc/inittab file. The inittab file contains what are run levels, what init has to do in each run level and what is the default runlevel etc. /boot/vmlinuz-2.6.18-194.17.1 file: vmlinuz is a compressed Linux Kernel image which is used at the time of booting Linux operating system. Vmlinuz stands for virtual memory Linux kernel zipped. /boot/System.map-2.6.18-194.17.1.el file: This is a map file used by kernel. This file contains memory location mapped to the kernel variables or functions. Again this file is used by vmlinuz kernel image at the time of booting to set symbol names. /boot/grub/grub.conf : This file is used for boot loader grub to load grub related configuration so that this is used at the time of booting.

Why and How to install the LTS kernel in Arch Linux
Installing the LTS kernel in Arch Linux is recommended if you want more stability. But what is the kernel? What is the difference between the default and the LTS kernels? Which one should you use? You can find out in this video. I first recommended the LTS kernel in the video 10 Things to do first in Arch Linux https://youtu.be/jW4GFGOIUjc?list=PLSmXPSsgkZLt66s-M_gfQtMakc8iYJY6M In this video, I provide more details why I prefer the LTS kernel. To install the LTS kernel in Arch Linux, do the following steps. First, check your current kernel version: uname -r If it is not LTS, install the LTS kernel: sudo pacman -S linux-lts Update your bootloader, if you use GRUB run this command: sudo grub-mkconfig -o /boot/grub/grub.cfg Reboot your system. After the reboot, you should see the GRUB menu, if you don’t see it, press SHIFT or ESC key during the boot time to enter the menu. Then go to the Advanced options, and select to boot with the LTS kernel. After you logged in your system, check the kernel version and make sure it is an LTS version: uname -r Now, you can remove the latest kernel and keep only the LTS kernel: sudo pacman -R linux If you keep both kernels, Arch Linux will use the latest kernel by default after you reboot your system. I prefer the LTS kernel.

How to repair grub bootloader in Kali Linux 2.0 for dual boot Windows and Linux
How to repair grub bootloader in Kali Linux 2 0 for dual boot Windows and Linux ================================================ Hello. I am sure there are plenty of newbies around when it comes to linux, myself included. This is a guide of how to repair grub in the event your windows 10 removed the grub during the installation. First thing that you'll need to do is to boot from a kali linux live cd. After that, go to gparted so that you can get to see where kali was installed: usually it's in the file system that ends with ext4, depending with the file system you used during the installation. In my case, the kali linux system was in sda5, but it varies with different systems.

Linux Boot Process (RHEL 7 Latest)  From ServerGyan
Linux Boot Process (REHL 7) 1- The machine is powered on. The system firmware (BIOS --Basic Input/Output System or UEFI -- Unified Extensible Firmware Interface) runs POST, and starts to initialize some of the hardware. You can configure this using F2 on your system/ server. 2- The system firmware searches for a bootable device, either configured on BIOS or UEFI boot firmware or by searching master boot recored (MBR).This order is configured in BIOS. You can configure this using F2 screen for by pressing certain key combination. 3- The system firmware reads a boot loader from disk, then passes control of the system to boot loader. On REHL 7 this will be GRUB2 You can configure this using grub2-install 4- The boot loader loads configuration from disk and presents the user with possible configuration to boot. You can configure this using /boot/grub2/grub.cfg 5- Either user makes a choice or automatic timeout happens, the boot loader loads the configured KERNEL and INITRAMFS from disk and places then in memory. An INITRAMFS is a gzip-ed CPIO archive containing kernel modules for all hardware necessary at boot, init-scripts and more. ON RHEL 7, the INITRAMFS contains an entire usable system by itself. You can configure using: /etc/dracut.conf 6- The boot loader hands control of the system over to kernel, passing in any options specified on kernel command line in boot loader and the location of the INITRAMFS in memory. You can configure using: /etc/grub.d/ /etc/default/grub, and /boot/grub2/grub.cfg 7- Now the kernel initializes all hardware for which it can find a driver in the initramfs, then executes /sbin/init (as PID 1). On REHL 7 the initramfs contains a working copy of systemd as /sbin/init, as we all a udev daemon. Configure using init and command line parameters. 8- The systemd instance from the initramfs executes all unit of initrd.target target. This includes actual mounting on /sysroot configure using /etc/fstab 9- The kernel root file system is switched form initramfs root file system to system root file system that was previously mounted on /sysroot.systemd then re-executes itself using a copy of systemd installed on the system. 10- Systemd looks for a default target, either passed from the kernel command line or configured on the system, then starts (and stops) units to comply with the configuration for that target, solving dependencies between units automatically. In its essence, a systemd target is a set of units that should be activated to reach a desired system state. These targets will typically include at least a text-bases login or a graphical login screen with appear.

Invaders, i386 multiboot-compliant kernel game for GRUB
invaders [1] is the game for invading from boot menu. This is a clone of Space Invaders, just not your typical clone. Not in ncurses, or any graphics. You need to load it with GRUB, or any loader can boot it. It has different graphics designs, the aliens don't group up in a rectangular box, they fly down in line formation and zig-zag pathway with several lines, and they do not fire. You can have up to five shots at any given time. I couldn't compile it, I think it's due to 64bit, might need to set up the cross-compiling for i386, but I didn't try and it wouldn't help me to record the GRUB. And from the glance of the source code, it directly accesses to the video buffer 0xb8000. An emulator is the answer, so I compiled a QEMU 2.5.0 i386-softmmu, and that's what you saw in recording. I tried to use `-curses` it works partially in terminal, the arrow keys didn't register, but fire [space] did. I decided to go with `-sdl` with resizing. Anyone wants to fork it for making it a regular program, or dual for booting and normal program? It's quite unique, worth getting an update after nearly 15 years. And go check out the author's website's homepage, there is some kind crazy stuff going on there, trains and even built his own 3D printer, that guy must be a wizard by night. $$$$ # with qemu (i386-softmmu) % pc-bios/qemu-system-i386 -kernel invaders -sdl $$$$ * Version 1.0.0 (2001-05-22) * In C * By Erik Thiele * GPLv2 [1]: http://www.erikyyy.de/invaders/
