GRUB and initrd: Load the OS on the Boot Process. It does some health checks to the system. When they’re done executing, they pass control of the computer back to the BIOS and and the PC enters a basic, usable state and is ready to begin. On a disk that contains valid bootstrap code, the last two bytes of the MBR should always be 0x55 0xAA.5If the last two bytes of the MBR do not equal 0x55 and 0xAA respectively, the BIOS will assume that the disk is not bootable and is not a valid boot option – in this case, it will fall back to the next device in the boot order list (as configured in the BIOS setup). The boot program then loads the next stage, which in the case of Oracle Solaris, is GRUB itself. If the BIOS does not find a device, it will try the next device in the list. The filesystem header, which will contain information specific to and important for the filesystem itself. At this point, you’ll normally be presented with an option to quickly hit a key to enter the BIOS setup from where you can configure hardware settings and control how your PC boots. always load the bootsector of the 3rd partition) and the offset of the boot code within the partition bootsector might change (e.g. The bootloader must also obtain information about the underlying machine hardware (either via the BIOS or on its own) in order to correctly load the desired operating system from the correct partition and provide any additional files or data that might be needed. Boot sequence is the order in which a computer searches for nonvolatile data storage devices containing program code to load the operating system (OS). The BIOS then looks at the sequence of storage devices identified as boot devices in the CMOS Setup. An error at this point is almost always a hardware problem. BIOS is short for Basic Input-Output system. BIOS is the main part of Booting process of a Computer. As covered above, the bootstrap code in the MBR will usually load … The CPU follows the JMP instruction and seeks to the beginning of the bootstrap code contained within the partition bootsector, and starts to execute. Depending on the filesystem, this can be several sectors in length, or however long it needs to be to fit this stage of the bootloader. Without it (such as on floppy disks), the entire disk could only contain one partition, which means that you can’t have things like different filesystems on the same drive, which in turn would mean you could never install Linux and Windows on the same disk, for example. Please copy/paste the following text to properly cite this HowStuffWorks.com article: Copyright © 2021 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company. ↩, Assembly is the most primitive programming language, and consists of individual instructions directly read and executed by the CPU. Booting from the network involves a different process on systems with BIOS firmware. Here are the steps − All rights reserved. Once your PC has been powered on, the BIOS begins its work as part of the POST (Power-On Self Test) process. The exact layout of a partition depends what filesystem the partition has been created or formatted with, but generally looks something like this: Again, depending on the OS and filesystem, the exact layout of the partition will certainly differ. Easy-peasy-lemon-squeezy, as my wife would say!! [In … Here is a rough sequence of events for the default installation of Debian with the Linux kernel on the typical PC platform. Whenever you turn on your computer, the first thing you see is the BIOS software doing its thing. This typically includes information about: Any special drivers, such as the ones for small computer system interface (SCSI) adapters, are loaded from the adapter, and the BIOS displays the information. It looks for a peripheral component interconnect (PCI) bus and, if it finds one, checks all the PCI cards. GRUB 2 is a powerful, modular bootloader more akin to an operating system than a bootloader. Over time and with better technology, erasable ROM chips were developed that could be cleared by placing them in a box and blasting them with a dosage of UV (ultraviolet) radiation, then reprogramming their contents with ROM chip programming hardware. This boot sector is called the Master Boot Record (MBR). On IBM-compatible PCs (basically, everything) the final two bytes of the 512-byte MBR are called the boot signature and are used by the BIOS to determine if the selected boot drive is actually bootable or not. The actual bootloader file for GRUB 2 is not a file called GRUB2, but rather a file usually called core.img. After a firmware and hardware initialization process, which depends on the machine's architecture, the kernel is started by means of the boot loader GRUB 2. It’s currently used in Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10, as well as Windows Server 2008 and Windows Server 2012. Once NTLDR is loaded and executed by the second-stage bootloader, it executes a helper program called NTDETECT.COM that identifies hardware and generates an index of information about the system. The BIOS will try to initiate the boot sequence from the first device. … What that means is that technically the actual bit indicating that a partition is bootable can actually be present (set to a value of 0x80) one more than one (or all!) The core functionality of GRUB 2 is supplemented with modules, normally found in a subdirectory of the /boot/grub/ directory. This key is often displayed during the boot process with a message “Press F2 to access BIOS”, “Press to enter setup”, or something similar. Because of how little space is allocated for the bootstrap code in the partition bootsector, the code it contains normally ends with another JMP command instructing the CPU to jump to the next sector in the partition, which is often set aside for the remainder of the partition code. It is a self-contained bootloader with many more options, especially designed to be compatible with newer functionality in modern operating systems and designed with EFI and GPT in mind (though only certain versions of BOOTMGR support loading Windows from a GPT disk or in a UEFI/EFI configuration). All of the major bootloaders mentioned below have support for loading multiple operating systems, a process known as “dual-booting” or “multi-booting.”. 1. First and foremost, the MBR contains something called the partition table, which is an index of up to four partitions that exist on the same disk, a table of contents, if you will. It checks the PS/2 ports or USB ports for a keyboard and a mouse. ↩, Almost every major hardware component now has firmware controlling it baked into its logic hardware, but we’re ignoring microcontroller firmware here. Boot refers to the process of launching the operating system. Looking to the appropriate boot drive, the BIOS will first encounter the boot record, which tells it where to find the beginning of the OS and the subsequent program file that will initialize the OS. When your PC is first powered up, a lot happens. The power supply takes some time until it … However, for legacy compatibility reasons, the MBR almost always loads the first sector of the active partition, meaning another only-512 bytes. Until recently, most computers used the Basic Input Output System (BIOS or legacy BIOS) for managing the boot process. The BIOS will try to initiate the boot sequence from the first device. "Boot" is short for "bootstrap," as in the old phrase, "Lift yourself up by your bootstraps." The differences between EFI/GPT and BIOS/MBR. On FAT32, this is called the FAT (file allocation table). Once the instructions are found, the CPU takes control and loads the OS into system memory. Along the way, you'll learn about various other boot … Next, the BIOS checks to see if this is a cold boot or a reboot. Once control of the PC has been handed-off from the BIOS to the bootstrap code in the MBR and from the MBR to the bootstrap code in the partition bootsector, and from there there to the executable boot files on the active partition, the actual logic involved in determining which operating system to load, where to load it from, which parameters/options to pass on to it, and completing any interactions with the user that might be available, the actual process of starting the operating system begins. The boot process can be initiated in one of a couple ways. 440 bytes is incredibly small. Once the OS initializes, the BIOS copies its files into memory and the OS basically takes over control of the boot process. After pressing the correct keyboard command from the previous … When that got old and tiring, electrically-erasable programmable ROM (EEPROM for short) was developed – with it, an electronic signal on specially-selected pins of the EEPROM chip would trigger an erase, and the chip could be programmed directly from where it was located on the motherboard. Since it did not find the correct system files, it could not continue. The kernel is often referred to as the core of any operating system, Linux included. The Role of POST in the Startup Process . Step 4. Bios boot process BIOS stands for Basic Input / Output System. The following diagram demonstrates the steps involved in a system boot process −. The computer system undergoes several phases of initialization from the power-on event until it offers the fully functional operating system (OS) to the user. It turns out that, during this boot sequence, the BIOS is doing a remarkable amount of work to get your computer ready to run. If you have ever left a disk when you restarted your computer, you have probably seen this message. After the GRUB boot sector code loads the rest of GRUB into memory, the boot process continues. NTLDR stores its boot configuration in a simple, text-based file called BOOT.INI, stored in the root directory of the active partition (often C:\Boot.ini). The Initial RAM Disk (intrd) is designed to … An end-of-sector marker, very similar to the 0x55 0xAA boot signature we saw earlier in the MBR. This hard drive is known as “the boot device,” “startup disk,” or “drive 0” and can usually be picked or set in the BIOS setup. Thus ends the lengthy journey that begins with the push of a button and ends with an operating system’s kernel loaded into the memory and executed. The BIOS code is baked into the motherboard of your PC, usually stored on what is called an EEPROM 1 and is considerably hardware-specific. Your operating system is a very sophisticated boot program that takes total control over your computer. More information about NTLDR, BOOT.INI, and NTDETECT.COM can be found in the linked articles in our knowledgebase. In the diagram below, the boot sequence for all standard computers and operating systems is shown: As you can see, the boot process is broken down into several major components, each of which is a completely-separate subsystem with many different options and variations. The BIOS is the lowest level of software th… Computers manufactured in the last few years allow you to enter the BIOS setup using one of the five keys shown below during the boot process. It does this by checking the value at memory address 0000:0472. partition(s) simultaneously! Since this first block, the boot-block, is small and the bootloader is very minimalist and can’t do much else, for example, read a file system or load a kernel image. instead of being the first 2 KiB of the partition, it might be the second KiB or 6 KiB starting from the 2nd multiple of the current phase of the moon) – but the basic concept remains the same. UEFI has a detailed setting menu, more useful than traditional BIOS. The POST process ends when the BIOS detects a valid system disk, reads the … 1. The very first (three) bytes of the partition bootsector contain a single JMP instruction, telling the CPU to skip xx bytes ahead and execute the next stage of the bootloader from there. Every hard disk has an MBR, and it contains several important pieces of information. It’s low-level software that resides in a chip on your computer’s motherboard. If there are any external peripherals connected to the computer, disconnect them. ↩, It’s the BIOS that’s responsible for a variety of error messages such as “. This article summarizes the process by which traditional BIOS PCs load an operating system, covering the basics and details of the BIOS, MBR, and bootsector. The actual bootloader files on the disk form the final parts of the boot loading process. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. This is an invalid configuration and can cause many different boot problems though! When your computer powers on and starts running your operating system, it goes through a series of operations before it actually starts your operating system. Of course, this is an easy fix. BOOTMGR is the newer version of the bootloader used by Microsoft Windows, and it was first introduced in the beta versions of Windows Vista (then Windows Codename Longhorn). Depending on the OS you’re loading, it might actually look up a hard-coded partition instead of the active partition (e.g. The BIOS code is baked into the motherboard of your PC, usually stored on what is called an EEPROM 1 and is considerably hardware-specific. The startup routines and overall functionality of the simpler components like the RAM and PSU is hardwired into them as a series of logic circuits (AND/NAND and OR/NOR gates), while more complicated parts such as the video card have their own microcontrollers that act as mini-CPUs, controlling the hardware and interfacing with the rest of your PC to delegate and oversee the work. In BIOS based system, MBR(Master Boot Record) is read from disk and the stage1 boot loader is activated(446bytes) and it’s task is to load stage2 boot loader that resides in the first MB of the disk ↩, In fact, the BCD file is a standard Windows registry hive, and it can be mounted for editing with tools like regedit.exe. The BIOS loads when your computer starts up, and the BIOS is responsible for waking up your computer’s hardware components, ensures they’re functioning properly, and then runs The BIOS then displays some details about your system. As each individual component receives life-giving electricity, it is powered up and brought online to its initial state. Most of the people are not interested to know about booting process. While GRUB eventually won out over Lilo and eLilo, it was replaced with GRUB 2 around 2002, and the old GRUB was officially renamed “Legacy GRUB.” Confusingly, GRUB 2 is now officially called GRUB, while the old GRUB has officially been relegated to the name of “Legacy GRUB,” but you’ll thankfully find most resources online referring to the newer incarnation of the GRUB bootloader as GRUB 2. This article explores the Linux boot process from the initial bootstrap to the start of the first user-space application. The BIOS is where hardware meets software for the first time, and where all the boot magic begins. Windows NT, 2000, and XP as well as Windows Server 2000 and Windows Server 2003 use the NTLDR bootloader. On modern filesystems for newer operating systems, the bootstrap code can take advantage of enhanced BIOS functionality to read and execute more than just 512 bytes, but in all cases, the basic steps remain the same: The bootstrap code in the partition is not the end of the road, it’s only another step along the way. When working properly, the boot process is a well-oiled machine, but when disaster strikes, it can be a very difficult process to understand and debug. Once the BIOS POST and AddOn ROM procedures have completed, the BIOS loads the first 512 bytes from the hard drive of the selected boot device – these 512 bytes are what is commonly known as the MBR, or the Master Boot Record. At the Boot interface, select UEFI/BIOS Boot Mode, and press Enter. The BIOS has tried to boot the computer off of the disk left in the drive. If no disk in the boot device list has the correct 0x55 0xAA boot signature, the BIOS will then display an error such as the infamous “No boot device is available” or “Reboot and select proper boot device.”. RELATED: What Does a PC's BIOS Do, and When Should I Use It? It must also read its own configuration file from a regular file stored on the boot partition’s filesystem, so it needs to at the very least have full read support for whatever filesystem it resides on. Electrical components of the PC are initially responsible for bringing your computer to life, as debouncing circuits take your push of the power button and trigger a switch that activates the power supply and directs current from the PSU to the motherboard and, mainly through it, to all the various components of your PC. This file is the last piece of the bootloader puzzle, and there are usually no restrictions as to its size or contents, meaning it can be as large and as complicated as it needs to be to load the operating system kernel from the disk and pass on control of the PC to the OS. ↩, There is a huge caveat emptor here: the bootable/active flag is actually a property of the individual (one of four) partition record, and not the partition table (list of partition records) or the MBR itself. Entering UEFI Settings for Windows 8: Open the Charms bar and click the Settings button. Earlier we mentioned that an important part of the BIOS’ work is to detect and map connected hard disks. the bootstrap code can’t just tell the CPU to JMP to location 0xABC and execute the boot file from there) – it’s a normal file stored amongst other normal files in the filesystem on the disk. UEFI runs in 32-bit or 64-bit mode, and the addressable address space is increased based upon BIOS, the boot process is much faster. Some resources that can come handy when troubleshooting the bootloader are listed below: These additional articles and resources in our wiki and from other websites online contain additional information relevant to this topic: Originally, the BIOS was stored on what was termed a ROM (“read-only memory”) chip: the BIOS code was hard-coded into the chip and could never be changed. As discussed previously, there are many different bootloaders out there. Unlike Legacy GRUB, the GRUB 2 configuration file is more of a script and less of traditional configuration file. While the executable bootloader files could theoretically contain hard-coded information pertaining to the operating systems to be loaded from the disk, that wouldn’t be very useful at all. If the computer is already running a local user, including root or an unprivileged user, the user can programmatically initiate the boot sequence by using the GUI or command line to initiate a Information about the device's operating system, Information about other identifiers assigned to the device, The IP address from which the device accesses a client's website or mobile application, Information about the user's activity on that device, including web pages and mobile apps visited or used, Information about the geographic location of the device when it accesses a website or mobile application. There are 4 phases to starting up the system: 1. ↩, On a little-endian machine like all x86 CPUs, that would be a single word 0xAA55 while on a big-endian architecture like PowerPC, it would be read and written as 0x55AA. First, if power is turned off, turning on the power will begin the boot process. Given how tiny the bootstrap code section of the MBR is, the only useful purpose it can really serve is to look up another file from the disk and load it to perform the actual boot process. On a correctly-created MBR disk, only one partition can be marked as active at a time.4. This section briefly describes some of those activities for a typical PC. After Windows is installed, if you need to switch firmware modes, you may be able to use the MBR2GPT tool.. Kernel. Well, to put things in context, 440 bytes is only 0.3% of the capacity of an ancient 1.44 MiB floppy disk – barely enough to fit any form of useful code – and way, way too small to do something as complicated as call up the operating system kernel from the disk. BIOS means Basic Input Output System. Typically, a Macintosh structure uses ROM and Windows uses BIOS to start the boot sequence. GRUB’s configuration file containing a whitespace-formatted list of operating systems was often called menu.lst or grub.lst, and found under the /boot/ or /boot/grub/ directory. After checking the CMOS Setup and loading the interrupt handlers, the BIOS determines whether the video card is operational. If it does not find the proper files on a device, the startup process will halt. While a number of different bootloaders have existed for Linux over the years, the two predominant bootloaders were Lilo and GRUB, but now most Linux distributions have coalesced around the all-powerful GRUB2 bootloader. To access your BIOS, you’ll need to press a key during the boot-up process. The BIOS is the lowest level of software that interfaces with the hardware as a whole,2 and is the interface by means of which the bootloader and operating system kernel can communicate with and control the hardware. Another bootstrap code segment, containing the next stage of the bootloader process. It’s the BIOS that’s responsible for a variety of error messages such as “keyboard error or no keyboard present” or warnings about mismatched/unrecognized memory. BOOTMGR marked a significant departure from NTLDR. A value of 1234h indicates a reboot, and the BIOS skips the rest of POST. We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services. Regardless of whether the BIOS was configured to boot from a local hard disk or from a removable USB stick, the handoff sequence is the same. The bootloader process is certainly a lot more nuanced and complicated than most realize, and it has both been designed and evolved to work in a fairly-standardized fashion across different platforms and under a variety of operating systems. This significantly more-complicated bootstrap code must actually read the table-of-contents for the filesystem on the partition,7 The second-stage bootloader from older versions of file systems oftentimes placed complicated restrictions on the bootloader files they needed to load, such as requiring them to appear in the first several kilobytes of the partition or being unable to load non-contiguously allocated files on the partition. The implementations of each component can differ greatly depending on your hardware and operating system, but the rules they follow and the process by which they work are always the same. Common keys you may need to press include Delete, F1, F2, and Escape. They assume control of the computer and its display, and let you do things like set up RAID arrays or configure display settings before the PC has even truly finished powering up.
