Performing a Boot Repair on Ubuntu 22.04 step by step instructions
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:
- 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.
- Make sure you select the option to “Try Ubuntu” since we do not want to reinstall Ubuntu – that is a last resort!
- After your PC is loaded into the live environment, open a command line terminal and use the following
aptcommands to install the Boot Repair tool.
$ sudo add-apt-repository ppa:yannubuntu/boot-repair $ sudo apt update $ sudo apt install -y boot-repair
- Once the application is installed, launch it with the following command.
The application will begin scanning your hard drive for installations, and this could take a few minutes.
- The first thing you should try now is the “Recommended repair” option. This will scan for and fix some of the most common boot issues.
Boot Repair will then perform this function. When it is done, you can reboot your system to see if that fixed the problem.
- 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.”
In this menu, you have the option to reinstall GRUB or choose a new location to store the boot loader configuration, which can be helpful if you suspect that GRUB is preventing you from booting. You can also scan the file system for errors and a slew of other things.
In this tutorial, you saw how to install Boot Repair in a live Ubuntu environment and use it to troubleshoot boot issues on Ubuntu 22.04 Jammy Jellyfish Linux. Boot issues can be very frustating, but this simple tool can check for all of the most frequent issues and get your PC back up and running in a few minutes. In a worst case scenario, reinstalling GRUB can remedy issues with your boot loader.
