Performing a Boot Repair on Ubuntu 22.04 step by step instructions



DID YOU KNOW?
GRUB is the boot loader for Ubuntu. If your system is having trouble loading Ubuntu, it is usually indicative of an issue with GRUB trying to find the operating system. The instructions in this guide will help repair GRUB and point it to your operating system’s boot files.

Before starting, it should be noted that some of the more basic boot issues can be remedied by booting into recovery mode. To do so, press the Escape key while the computer first begins booting up. You will be presented with the following GRUB menu:

In recovery mode, you can choose from various options for fixing your system: clean (make free space), repair broken packages, check all file systems for errors, update the GRUB boot loader, etc. These are only basic options but will not perform a full boot repair which we will cover next:

Boot Repair

  1. The first thing we need to do is boot into a live environment so that we can do some troubleshooting. For this, we recommend creating a bootable Ubuntu 22.04 USB disk. See our other tutorial for help with that. After you have that ready to go, boot into the live environment at system start.

    $ sudo add-apt-repository ppa:yannubuntu/boot-repair
    $ sudo apt update
    $ sudo apt install -y boot-repair
    
  4. Once the application is installed, launch it with the following command.

  6. In case you are still having trouble, you can select the “Create boot info summary” option, which will run diagnostics and give you a text summary to share with experts for more help. The other path you can take is under “Advanced options.”
