This GRUB Customizer Tutorial explains how to install the GRUB Customizer. The Grub Customizer by Daniel Richter allows the graphical configuration of the GRUB 2 and Burg boot loaders and is used by many linux distributions. It can be used to make simple changes such as the boot sequence (order of the menu entries) or to set the waiting time until the automatic start of the standard entry. The Grub Customizer does not provide a complete graphical interface for configuring all the subtleties of GRUB 2. How to customize the GRUB background image is shown here.

Install grub-customizer

1. Add PPA Repository

You can add the PPA repository with the following command.

add-apt-repository ppa:danielrichter2007/grub-customizer

2. Update

apt update 

3. install GRUB Customizer

You can now install the GRUB Customizer with the following command.

apt install grub-customizer -y

Now you can use GRUB Customizer.

Edit the GRUB menu order

Under the List Configuration tab we can change the Grub menu order. So if you want Windows at the top of the list, then you can. Select the menu item and use that arrows to move it around the menu.

Selecting an entry and right clicking on that entry enables us to edit the information used when booting with that entry.

Default Boot Entry

Your dual boot laptop may see that you work more with Windows than Linux, that’s cool with me.

In General Settings we can change the default entry. This can be the first entry, in my case Ubuntu, or we can change it to another option. In the above image I have set it to Windows. So if I power up the laptop and not touch it, it with automatically boot to Windows.

Insert cool image here!

What was the first thing that I used Grub Customizer for? To add a „cool“ background to my Grub menu.

Clicking on the background image button, we can load a JPEG image to use as a background.

So I inserted this vanity project cool image.

We can see a preview of the Grub screen, and it looks good.

We can also edit the colour of text, highlighted text, and text backgrounds. We can also change the font to something cool, but do be careful and some fonts may not work as expected.

When we are happy, click on Save and then reboot the machine to see your handiwork!
