Grub is the screen you see when you start your machines. Over a period of time with all the kernel updates, the grub is overloaded and becomes ugly. In many cases you wont be using an old kernel unless there is something dramatically wrong with the new one. So let’s see how to clean the grub and make it look slimmer and neater. You can do it the hard way every time or you can just install Grub Customizer which will solve the problem for you.
Grub Customizer is a graphic utility to customize GRUB 2 of your linux machine. Use the following commands to install the Grub Customizer.
1. sudo add-apt-repository ppa:danielrichter2007/grub-customizer
2. sudo apt-get update
3. sudo apt-get install grub-customizer
Hope this keeps your startup screen and GRUB 2 clean.
