Installing Grub CustomizerThe tool in question is called Grub Customizer, created by Daniel Richter. He’s provided a PPA to make installing the tool quick and easy.
Open a terminal window (Ctrl+Alt+T or Applications > Accessories > Terminal) and type in the following commands.
Grub Customizer will now show up in the Applications > System Tools menu.
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
Or you can open it from the command line.
Hide Boot Menu OptionsOver time, your boot menu can get cluttered with old versions of the Linux kernel. In a previous article, we showed you how to remove these manually; Grub Customizer makes this process much easier.
When Grub Customizer starts up, you’ll see a list of all the items that show up in the boot menu.
To hide entries that you don’t want to see anymore, simply uncheck the checkbox next to them.
Click the Save button at the top-left to make your changes permanent.
You can uncheck entire sections if you don’t want Grub2 to probe for new operating systems, or give you the option to test your computer’s memory.
Note that, unlike the manual method, this process does not actually remove the kernels from your computer, it just hides them from the boot menu.
Customize Grub BehaviorGrub Customizer can do much more than hide boot menu entries! Opening up the Preferences window lets you customize almost every aspect of Grub.
For example, you can set the default boot menu entry to a certain position, or a specific item.
If you’re bored by the default white-text-on-black-background look of Grub2, you can add a background image and customize text colors.
And, for Grub2 experts, you can set advanced settings much more easily than by editing the configuration files manually.
Grub Customizer is a great addition to any Linux installation that uses Grub2!
Thanks to How-To Geek commenter Hugues for recommending this program!
