In this article, I will show you how to use Boot Repair on Ubuntu. I will be using Ubuntu 18.04 LTS for the demonstration. Let’s get started.

Installing Boot Repair:

You usually install Boot Repair on an Ubuntu live boot as you may not be able to boot into your operating system installed on the hard drive at that time. So this is what I am going to focus on in this article.

You can make an Ubuntu bootable USB stick of any latest version of Ubuntu Live DVD ISO image. I have a dedicated article on that topic, which you can read at https://linuxhint.com/rufus_bootable_usb_install_ubuntu_18-04_lts/

Once you’re done with making a bootable USB stick of Ubuntu Live DVD ISO image of your choice, boot from it and select Try Ubuntu without installing from the GRUB menu as shown in the screenshot below.

Now connect to your network and open a Terminal window (Press <Ctrl> + <Alt> + t)

Boot Repair is not available in the official package repository of Ubuntu. So you have to install it from the Boot Repair PPA.

Now add the PPA of Boot Repair with the following command:

$ sudo add-apt-repository ppa:yannubuntu/boot-repair

Now press <Enter> to continue.

The Boot Repair PPA should be added and the APT package repository cache should be updated.


Now you can install Boot Repair with the following command:

$ sudo apt install boot-repair

Now press y and then press <Enter> to continue.

Boot Repair should be installed.

Now you can start Boot Repair Application Menu:

You can also start Boot Repair from the command line with the following command:

$ boot-repair

Boot Repair should start.

As you can see, there are many advanced options in Boot Repair.

I will talk about these in the next sections of this article below.

Backing Up Partition Table with Boot Repair:

You can backup your partition table from Boot Repair. It is important as if your partition table gets corrupted somehow, you will be able to recover the partitions and get your data back. Otherwise, you may loose all your data.

To backup your partition tables, just click on Backup partition tables, bootsectors and logs button as marked in the screenshot below.

Now select a location where you want to save the partition table data and click on Save.

Once the partition table is saved, you should see the following message. Just click on OK.

Now you should be able to find a zip file in the directory that you selected earlier as you can see in the screenshot below.

Repairing File Systems with Boot Repair:

At times, your file systems may get corrupted and Ubuntu won’t be able to fix it automatically on boot. It may result in boot failure. You can fix the file system with Boot Repair. Just check the Repair file systems option from the Main options tab as marked in the screenshot below and click on Apply.

It should take a while to repair the filesystem and fix boot problems. Once it’s done, you should be able to boot into your installed operating systems as usual again.

Changing GRUB Location with Boot Repair:

You can tell where GRUB is installed on your hard drive from the advanced options of Boot Repair. If you have multiple hard drives installed on your computer that has GRUB installed, then you may want to set which hard drives you want to repair here.

To change GRUB location, go to the GRUB location tab of Boot Repair. Now select the hard drive partition from the OS to boot by default drop down menu. If you’re using UEFI based motherboard, then also select the hard drive partition which is used as EFI System Partition from Separate /boot/efi partition drop down menu.
