June 2010) (Learn how and when to remove this message) In Unix -like operating systems , a boot folder is the directory which holds files used in booting the operating system, typically /boot . The usage is standardized within Linux in the Filesystem Hierarchy Standard .
The first stage bootloader, which is a part of the MBR, is a 512-byte image containing the vendor-specific program code and a partition table. [6] As mentioned earlier in the introduction part, the first stage bootloader will find and load the second stage bootloader. [6] It does this by searching in the partition table for an active partition. [6]
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 ...
The boot loader in or loaded by the MBR displays a menu of logical drives and loads the selected boot loader from the PBR of that drive. An example of a computer with one operating system per storage device is a dual-booting computer that stores Windows on one disk drive and Linux on another disk drive.
GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
In the example 2 above, GRUB 2 stores its core.img in a BIOS boot partition. When used, the BIOS boot partition contains the second stage of the boot loader program, such as the GRUB 2; the first stage is the code that is contained within the Master Boot Record (MBR).
To overcome this, Linux distributors encouraged users to create a partition at the beginning of their drives specifically for storing bootloader and kernel-related files. GRUB, LILO and SYSLINUX are common bootloaders. By convention, this partition is mounted on the filesystem hierarchy as /boot.
LILO (Linux Loader) is a bootloader for Linux and was the default boot loader for most Linux distributions [when? Unlike loadlin , it allowed booting Linux without having DOS on the computer. [ 3 ] As of 2009, most distributions have switched to GRUB as the default boot loader. [ 4 ]
