After turning on the power first starts the boot loader is a special program that determines the availability of operating systems on disk and manages their launch. Most Linux distributions, including Mint with the Grub bootloader.
The graphical interface of this program there. To change the appearance of its Windows it is possible by manually editing the configuration file /boot/etc/default/grub. However, there is another way to install third-party programs, giving the opportunity to change text settings using a graphical interface. An example of such a program Grub Customizer. In this article we will understand how to install Grub Customizer on Linux Mint 19.
Install Grub Customizer in Linux Mint
To install Grub Customizer standard tools — with the help of application Manager mintinstall — will not work, because the program is not in the official repositories. Will have to use a personal repository of a developer, but you need to add it to the list of sources to which the operating system is allowed access. This can be done in two ways. Via terminal or graphical interface.
Adding the PPA via terminal emulator
To add repository execute the command in the terminal:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
Then update the packages list (otherwise the system won’t see the new repository):
sudo apt-get update
Adding the PPA using the GUI
To find the tab to configure repositories in Linux Mint follow this path: Menu → System → software Sources. In the opened window, select PPA repository and click Add.
This opens another window, this time with a field to enter the name or address of the repository. There type in ppa:danielrichter2007/grub-customizer and click OK.
If the specified repository is found, the system will ask you to confirm adding it. Otherwise, check the spelling of the name (address).
After a minute or two will add two new source applications. When this happens, the system will prompt you to update the list of packages in the cache APT.
Click OK in the upper right corner to start the update. If this is not done, the system will not use the new repository, respectively, will fail to install Grub Customizer.
Install and run the program
When the repository is added, can be performed by installing Grub Customizer on Linux Mint 19 with the command:
sudo apt-get install grub-customizer
After another couple of minutes everything will be ready. To run the program there are two ways: through the terminal or through Menu → System. Grub Customizer doesn’t load immediately, it takes time to read information about the systems installed on the computer.
When the screen appears something like what you see in the screenshot, you can start changing the settings. How you configure Grub Customizer, see the separate article.
How to remove Grub Customizer
If the program you no longer need, you can remove Grub Customizer through the terminal with the command:
sudo apt-get remove --purge grub-customizer
Not to clog the system, you can delete the repository. In the terminal use this command:
sudo add-apt-repository --remove ppa:danielrichter2007/grub-customizer
sudo apt-get update
This can also be done using a GUI OS in the sources settings applications. Check the junk repository and click Delete, then confirm your action. Don’t forget to update your package list by pressing OK in the upper right corner.
Grub Customizer — a godsend for those who do not know how to work with configuration files. It can be used for a few minutes to customize the appearance and settings of the boot loader. Installation and removal should cause no difficulties if you follow the instructions from this article, but if issues do appear, do not hesitate to ask them in the comments.
