GRUB (GNU GRand Unified Bootloader)
An open source boot loader used to boot operating systems during start up, presenting users with a boot menu allowing them to choose between multiple operating systems installed on a computer.
What is GRUB?
GRUB (GNU GRand Unified Bootloader) is an open source boot loader used to boot operating systems during start up. It is the default boot loader for most Linux distributions and is also available for BSD, Solaris, and other operating systems.
When a computer first turns on, the BIOS initializes hardware components and then looks for a boot loader. GRUB allows the user to select which operating system to load at start up if multiple OSes are installed. It presents a boot menu with options for the various OSes and kernels available.
Some key features of GRUB include:
- Support for multiple operating systems - allows dual-booting Linux, Windows, macOS, etc.
- Modular design that makes it highly customizable
- Support for LVM and RAID partitions
- Support for multiple filesystems including ext, ReiserFS, XFS, FAT, and NTFS
- Graphical menu interface with background images and themes
- Password protection for boot menus
GRUB is highly flexible and customizable through editing its configuration file. Advanced users can tweak GRUB to alter boot options, change boot locations, set default OSes, customize menus, and more.
