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 Change default boot order, and waiting time on Linux (Multi-boot)
Editing GRUB using nano and Linux therminal to change boot menu settings: This video is describing how to change the boot order and booting wait timeout. If you don't like to use sudo at the begining of each command, you can type su and press Enter. It will ask for your password, and it would keep it. Ok, let's get started. Note: First, write or remember the order of your boot menu items, and keep in mind that line numbers start from 0, and Not 1. Open your terminal window by pressing Ctrl+Alt+T 1- Type:     sudo nano /etc/default/grub (This will open grub, which is the place for all these boot configs) 2- Find     GRUB_DEFAULT= X 3- Change the Value of X to the line number that you like to be your default boot. 4- To change the default waiting time, Find and change the value of Y in GRUB_TIMEOUT= Y 5- Press Ctrl+O to Save 6- Press Ctrl+X to Exit 7- Type:     sudo update-grub to update your settings That's it.

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.

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.

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.

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.

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.

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.

Linux: Set a GRUB 1 Password
The steps in this video work on GRUB1. These will not work in the newer GRUB versions. You will set a md5 encrypted password to protect Linux's boot and kernel options. Typically you will use a better password than the one presented in the movie!

AntiX Core - Custom Install Part II - Install a different Kernel
Antix Core by default comes with a free/libre/gnu kernel. Depending on your hardware, you may need a nonfree/non-gnu kernel. Luckily antix has you covered, but you'll need to install the kernel from the repos. We will show you how! Here are some notes to help you out. updating the kernel in antix (core install, but instructions work for base and full as well) if you need non-free firmware, you are going to need a non-free kernel. By default, antix-core comes with a gnu-libre-free kernel that does not include many firmware nor will it necessarily work with non-free firmware you install yourself. so to update your kernel, as root, apt-get update apt-cache search kernel antix (this will show you all the kernels available!) be careful to select the correct one. I'm using linux-image-3.11.5-antix.1-486-smp and linux-headers-3.11.5-antix.1-486-smp these are 32 bit kernels. 64 bit are available if you are using the 64bit version of antix when you have the kernels, as root type "update-grub" and your grub boot menu will automatically update with new entries for your new kernel. Your ORIGINAL KERNEL WILL STILL BE THE DEFAULT. Test out your kernel by selecting it from the boot menu. If all is well, then feel free to edit /boot/grub/menu.lst to move your old kernel to an option line and the new kernel to the top. Actually, if you just comment out the top antix menu entry, then the new default will be the latest kernel. Thanks for watching, and have Fun! d.o. antix.mepis.org antix.freeforums.org

Linux as a Boot Loader - Peter Chubb
Once upon a time, you could put a floppy disk with the Linux kernel on it into a PC and it would boot. Nowadays, you have to use a separate program (LILO, GRUB, U-Boot, Blob, LART, RedBoot, etc., etc.) to load Linux, set up some parameters, and then start it running. When you have new hardware, this sucks. You have to port not one but two programs that have intimate knowledge of the hardware. And you generally have to port USB stacks, Network drivers, etc.

Customize your PC GRUB . GRUB bootloader is the software that loads the Linux kernel. It is the first software that starts at a system boot.This program is responsible for detecting and loading any OS on your personal computer. --------------------------------------------------------------- If your computer is dual booted then by default PC boots to Linux. To manipulate it (if I want it to boot into windows by default ( I have ubuntu + windows installed ) ) you have to change GRUB file a little in my case if I want to boot into windows by default then steps are: execute sudo gedit /etc/default/grub then change GRUB_DEFAULT=0 value to you windows partition ( in my case it is 4 ) so I would change it to GRUB_DEFAULT=4 then save the file and update GRUB using sudo update-grub and reboot to see change ----------------------------------------------------- Like, Dislike, Share and Subscribe!
