A bootable device can be storage devices like floppy disk, CD-ROM, USB flash drive, a partition on a hard disk (where a hard disk stores multiple OS, e.g Windows and Fedora), a storage device on local network, etc. [7] A hard disk to boot Linux stores the Master Boot Record (MBR), which contains the first-stage/primary bootloader in order to be ...
boot.xxyy – these 512-byte files are backups of boot sectors, either the master boot record (MBR) or volume boot record (VBR), created when LILO overwrites a boot sector. xx and yy are the major and minor device numbers in hex; [ 5 ] for example, the drive sda has numbers 8, 0, hence its MBR is backed up to boot.0800 while the partition sda3 ...
The boot partition is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. For example, in the standard Linux directory layout ( Filesystem Hierarchy Standard ), boot files (such as the kernel , initrd , and boot loader GRUB ) are mounted at /boot/ . [ 1 ]
Version 7 Unix: /etc listing, showing init and rc Version 7 Unix: contents of an /etc/rc Bourne shell script. In Unix-based computer operating systems, init (short for initialization) is the first process started during booting of the operating system. Init is a daemon process that continues running
In Linux systems, initrd (initial ramdisk) is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs (from INITial RAM File System) refer to two different methods of achieving this. Both are commonly used to make preparations before the real root file system can be ...
When debugging a concurrent and distributed system of systems, a bootloop (also written boot loop or boot-loop) is a diagnostic condition of an erroneous state that occurs on computing devices; when those devices repeatedly fail to complete the booting process and restart before a boot sequence is finished, a restart might prevent a user from ...
The boot ROM of NXP systems on a chip (SOCs) support configuring the peripherals through specific pins of the system on a chip. On the i.MX6 family it also supports configuring the boot order through efuses. The boot ROM of several NXP SoCs have many ways to load the first stage bootloader (from eMMC, microSD, USB, etc.).
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project.GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular ...
