How To Tweak The Grub Customizer To Improve Your Dual-Boot Experience

It is no secret that most Linux users have at least two operating systems on a single machine. One being Linux and other…. Well in most cases is a Windows OS.

Grub, as it turns out is among the most widely used dual-boot mechanisms among Linux enthusiast. Based off a GNU project, the boot loader package does not only allow users to boot one of the multiple operating systems they have installed in their PCs but also gives them the ability to select a specific Kernel configuration.

Like most programs, it does sport some flaws a few of which are “No such partition” error message which sometimes appears when booting or having the last operating system that user installed at the top of the list every time they restart their computers even though the default is set for another operating system.

This isn’t much of a problem for those that have fingers readily placed on the arrow button every time they restart their PCs but it can spiral out of control when the Linux Kernel refuses to install properly because it boots into the wrong OS every time you need to restart after running an update on your Linux OS.

People have found a way around this but it requires typing in complex commands in the Grub menu which could be a bit intimidating for those new to Linux.
This tutorial is going to show you how to have the OS of your choice at the top of the list with having Grub mess things up.

Step One

The first thing you need to do is download a Grub customizer and interestingly with just this software and few tweaks, you will be to K.O both problems.
Download Grub customizer with these commands:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Step Two

With the customizer installed, you can now change the Grub OS boot order by simplifying
selecting the operating system of your choice and then click “Save”.


A little hint and some warning signs are that the Grub Customizer doesn’t run smoothly and you might find things cramped up in the “Advanced Option for” folders and since the arrow moves from one item at a time, you might end misplacing your entry if you try to move too quickly.
In the case that something like that happened like in this picture where Zorin 11 seem to disappear, don’t panic, it has just been moved to the “Advance Option for” folder.


Step Three

The third step is to head over to the “General Settings” on the Grub Customizer, and change the “Predefined” option to the “Previously booted Entry” this way the Pc will always boot to the last used OS when restarted thus you won’t be running into any problems when you have to restart after a Kernel update.
