Questions tagged [grub-legacy]

grub-legacy is the first revision of GRUB, the GRand Unified Bootloader. Grub legacy version numbers run up to 0.9x.

This tag is for GRUB Legacy (version 0.9x) only. For questions about versions 1.x and above, use the tag (note that versions numbered 1.9x are GRUB 2, not GRUB Legacy).

GNU GRUB (GRand Unified Bootloader) is a bootloader. It was originally intended as a common bootloader for various new operating systems conforming to the multiboot specification. Nowadays, many Linux distributions have adopted GRUB as their default bootloader.

There are two major versions of GRUB, with incompatible configuration files:

  • GRUB1, now known as GRUB Legacy, with version numbers up to 0.97;
  • GRUB2, with version numbers up to 1.98.
