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.

Cosa è GRUB
GRUB è la sigla che sta per "GRand Unified Boot loader" ed è il menu iniziale che ci permette di scegliere quale sistema operativo far partire nel caso in cui ne abbiamo più di uno installato sul nostro PC. la posizione di GRUB nel processo di boot: 1) accensione del PC 2) si attiva il BIOS (Basic Input/Output System) 3) viene letto il MBR (Master Boot Record), ovvero il primo settore del disco, per caricare in memoria ed eseguire il Boot Loader GRUB. Nei sistemi più recenti viene invece letta la partizione UEFI per caricare il Boot Loader 4) si attiva il Boot Loader GRUB. Se esiste più di un sistema operativo installato appare sempre il menu di scelta di grub, altrimenti non appare mai e lo si può richiamare tenendo premuto il tasto SHIFT 5) si attiva il Kernel Linux Gestione del menu GRUB A) gestione da terminale Qui di seguito elenco i file che compongono la configurazione di Grub. Tuttavia sconsiglio di modificare questi file a meno che non si sappia esattamente cosa si stia facendo: [*] /boot/grub/grub.cfg ⇒ file di configurazione principale [*] /etc/default/grub ⇒ file di configurazione del menu [*] /etc/grub.d/*.* ⇒ altri file di configurazione del menu si tratta di comuni file di testo, quindi facilmente modificabili, ma dato il loro scopo è anche facile, non conoscendo bene grub, fare disastri. Per chi è interessato, metto qui un riferimento di una guida per la modifica da terminale delle configurazioni (a vostro rischio) http://ubuntuforums.org/showthread.php?t=1195275 [*] update-grub ⇒ comando per aggiornare la configurazione (eseguito automaticamente dal sistema quando ad esempio si aggiunge un nuovo kernel) B) "Grub Customizer" un'interfaccia grafica per gestire Grub2 questo programma rende meno ostica la modifica di alcune opzioni di grub per coloro che vogliono qualche personalizzazione diversa dallo standard. Anche in questo caso però sconsiglio di modificare le opzioni tecniche di avvio delle diverse sessioni a meno che non si sappia esattamente cosa si stia facendo. Quello che si può fare senza grossi pericoli è ad esempio modificare il tema "grafico" di grub con la scheda "Impostazioni aspetto". Temi già pronti si possono trovare in rete, così come delle guide per crearne di nuovi. Installazione di Grub Customizer [*] https://launchpad.net/grub-customizer [*] sudo add-apt-repository ppa:danielrichter2007/grub-customizer [*] sudo apt-get update [*] sudo apt-get install grub-customizer Documentazione per approfondire il tema info -f grub -n 'Simple configuration' (documentazione presente nel sistema da terminale) http://www.gnu.org/software/grub/ http://it.wikipedia.org/wiki/GNU_GRUB http://wiki.ubuntu-it.org/AmministrazioneSistema/Grub http://members.iinet.net/~herman546/p20/GRUB2%20CLI%20Mode%20Commands.html http://www.gnu.org/software/grub/manual/grub.html https://help.ubuntu.com/community/Grub2

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.

DIY pt1: Building fast and small Linux kernel
https://www.kernel.org/ This kernel will be very fast, it will make your system r4espond 10 - 15% faster. U can do even better latency for desktop usage if U patch your kernel with ck-patch (CPU scheduler) Security will be defeated here, because it doesnt go with performance. U dont need to care if you dont have server. I will make other video for building very secured Linux kernel for servers and firewalls. Be very carefull with your hardware here, otherwise Ure kernel will not boot, pay attention wit CPU configuration, GPU configuration as well as chipset configuration... As I mentioned in video, this will work on every linux distro, just copy kernel in boot, install modules and select new kernel in grub.. For final small kernel image, it is very important to start from scratch with "make allnoconfig" otherwise, there will be needless feautures which will be hard to get rid off.. If somethings go wrong, just press "e" in grub and select your old kernel and uncheck old initrd image... which you will need to check with # because Our builded kernel doesnt requie initrd (i didnt cover this in video because i dont have and use initrd).... If everything go well, U can delete old kernel and initrd from boot and delete checked initrd image in grub.cfg.. be sure to check every of those selected kernel feautures and study them (some ary very complicated to understand but it will be worth), I will not explain them in video... Keep in mind that this feautures will improve performance on my current hardware or any intel in general.... If U use amd, it may be different but pretty similar. Also, pay attention to EFI support under "proc type and feautures" if U use UEFI bios mode. Also notice that i disablet etherent because im only using wireless This IS NOT How to, because it will not work if you just copy my config, it is more DIY, to help you build fast kernel once you know how to build one... This kernel wil be respondable with low latency level but it may be slow on high cpu loads, for example when u compiling with parallel options. U can change this if u change tickless system in general setup and scheduling system in Proc type... but this will defeat real-time latency... So, it all depends on you and your needs. In both cases, it will be much faster than generic kernel.

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!

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.

Hi Guys, Today I m gonna show you how to configure G.R.U.B (Boot Loader) GRUB Configuration file i.e grub.conf located in #cd /boot/grub use vim to edit the file #vim grub.conf i)on line no.10 default=0 defines how many o.s. to load with. ii) on line no.11 timeout =10 sets the counter, that the grub image will hold on the screen while booting iii) on line no.12 splashimage = (hd0,0)/splash.xpm.gz read below splashimage option consists of 2 parameter and image file location hd0:- means the 1st hard disk of the system 0 :- means the partition of the first hard disk. (for e.g. : in a system has 2 hard disk and in 1st hard-disk it got 3 drives c: d: e: and in 2nd hard-disk it got 2 drives f: g: then hard-disk1 called as hd0 and then hard-disk2 called as hd1. Partitions are numbered as c: - 0 d: - 1 e: - 2 f: - 3 g: - 4 } but in our condition we have only one hard-disk and single partition. we don't have to be worried about all these iV) splash.xpm.gz : is the image file which u see when your system starts, (.xpm.gz) is the format of the image which is used for this particular purpose. we can have our own image v) on line no. 14 title is the keyword followed by the title name you can have whatever title you want title mygrub restart the system to check Thanks for Watching

[ENG] Broken laptop's monitor: Disabling it and boot WITHOUT a visible GRUB menu
Blog post: http://antoniodanieleblog.blogspot.com/2016/09/dead-laptop-monitor-multiboot-possibility.html Disclaimer: http://antoniodanieleblog.blogspot.it/p/the-unknown-antoniodanieles-blog.html [ACTUAL DESCRIPTION] In this new video I show how to solve an intricated problem: What if your laptop's monitor is broken and you can't see the BIOS settings and the GRUB menu? In this video you're going to see: -How to disable the laptop monitor and force the use of an external one by using a kernel parameter. -How to use the grub-reboot command in an "user-friendly" way, by using a script to automatize everything. [ERRATA] 1) 04:17 From the video I thought it was obvious, but I'll sign it as an ERRATA anyway, the kernel option follows the format "video=INTERFACE:OPERATION", where INTERFACE is the name of the interface in the output of xrandr, and OPERATION is "d" for "disable" and "e" for "enable". 2) 07:29 Here I intend to say that you have to first boot to other systems WITHOUT the parameters, because you won't know them, and, after checking the output of xrandr, take note of it, return to the main distro and add the needed options. 3) 14:20 The script contains a fatal inattention, I forgot to add the command "exit" to the first if. The actual piece of code should be like this: if [ $# -ne 1 ] then echo "Fedora or Windows needed" exit fi 4) 17:00 This is a more general speech. If you still see the laptop monitor activated at the login manager, perform the login. While in Debian, the output of xrandr signals that the LVDS inteface is disconnected (therefore completely unusable), in Fedora, after the login, the screen is turned off but the interface is still connected.

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
