GRUB 2 bootloader is in continuous development. Some information may change over time, as features are added or removed and fixes introduced. For latest updates, please take a look at Updates section below.
This tutorial focuses on GRUB version 2, the next generation of the popular bootloader. If you are looking for the original (legacy) GRUB tutorial, please take a look at this article.
Welcome to the GRUB 2 bootloader tutorial! You must have read my GRUB legacy guide. In the last two and a half years, it alone has garnered some half a million views, proving to be quite popular and useful to computer users worldwide.
I want to recreate the same success with my GRUB 2 tutorial. My goal is to provide people running any flavor of UNIX-like operating systems or multi-booting their computers and using GRUB as their bootloader with a simple, no-nonsense, step-by-step, proven and working tutorial that should allow them to quickly, easily and painlessly control the boot sequence of their systems.
In this tutorial, you will learn how to work with GRUB 2, add and remove menu entries, customize titles and boot options, dual-boot and triple-boot operating systems, combine legacy GRUB and GRUB 2, and we will even see how Windows fits into this scheme. After that, we will learn how to recover from errors and mistakes.
