What is GRUB?

  • GRUB is acronym for GRand Unified Bootloader.

GRUB is a complete program for loading and managing the boot process. It is the most common bootloader for Linux distributions. A bootloader is the first software that runs when a computer starts. It loads the kernel of the operating system and then the kernel initializes the rest of the operating system: shell, display manager, desktop environment, etc.

总结：BootLoader负责加载内核。BootManager在于找到了多个引导，如果选择进入的系统。
