Any changes you made in in /etc/default/grub file will be reflected to the GRUB2.įirst, backup the /etc/default/grub file before making any changes. The /boot/grub/grub.cfg file is automatically generated by grub-mkconfig using templates from /etc/grub.d and settings from /etc/default/grub.
If you do anything wrong with this file, then you will surely be end up with broken system.
This is the main file to boot into the Linux OS. You shouldn’t edit or modify this file, unless you are much familiar with GRUB2. Warning: The default configuration file for GRUB2 is /boot/grub/grub.cfg. Like I already said we can configure boot loader settings from command line or GUI. I tested the steps given below guide on Ubuntu 16.04 and 18.04 LTS desktops, however these instructions might work on all Linux operating systems that uses GRUB2 boot loader. We can configure the settings either by directly editing the grub configuration file using any text editor or using any GUI applications like Grub-customizer.

In this tutorial, let me show you how to configure GRUB2 Boot Loader settings in Ubuntu system. And then the Kernel takes charge, and initializes the rest of the operating system. It is responsible for loading and transferring control to the operating system Kernel. GRUB boot loader is the first program that runs when the computer starts. GRUB stands for GRand Unified Bootloader. You could boot into runlevel 3 - the standard system without a graphical desktop - or runlevel 1 - a single-user mode designed for administrative tasks.As you probably know, GRUB2 is default boot loader for most Linux operating systems. For example, this would allow you to boot into different “ runlevels.” By default, your Linux distribution probably boots into runlevel 5, which generally starts the system with a graphical desktop. Or, you can select a boot option and press e to edit that menu entry’s boot options by hand. You can press c to open a GRUB2 command-line environment, where you can run various GRUB2 commands.

However, these tools aren’t as easy-to-use and helpful as the graphical system repair tools you’d find on a Windows installation disc. If you ever need to fix your Ubuntu system, the options here may help. Boot into recovery mode and you’ll see a list of options designed to help you troubleshoot and recover an Ubuntu installation. Other Linux distributions may provide something similar. Ubuntu also provides a “Recovery Mode” option here. The most recent kernel appears at the top of the list, has the highest version number, and is selected by default. Ubuntu configured GRUB to hide these options under “Advanced options for Ubuntu.” Select it and press Enter and you’ll see a list of Linux kernels you can choose to boot. You can switch to the older Linux kernel by rebooting into your GRUB boot loader and selecting the old kernel. For this reason, Linux distributions generally keep at least one older Linux kernel around. It may refuse to boot after you update, or you may experience hardware problems. However, in some cases, a new Linux kernel might have a problem on your system. This all happens automatically the next time you boot. To switch to a new Linux kernel, you have to reboot your operating system and boot into it. The Linux kernel is the core of the operating system, and new Linux kernels with updates and fixes often arrive via your Linux distribution’s package manager. GRUB2 is also where you can choose between your installed Linux kernels. Press Escape or reboot your computer to leave the memory-testing environment. Select it and press Enter to quickly perform a memory test without having to burn Memtest86+ to a disc or create a bootable USB drive from it. This menu entry will boot the Memtest86+ memory-testing tool. For example, Ubuntu offers a “Memory test (Memtest86+)” option. You can also access some additional tools here, although the exact options available will depend on your Linux distribution.

Your Linux distribution should automatically configure GRUB to list your other installed operating systems when you install it. If you have other operating systems installed - whether they’re Windows or other Linux distributions - you can use select and boot them from here.
