If you are having trouble booting into your Ubuntu 22.04 system, there is a tool called Boot Repair that can remedy a broad range of frequent issues. Usually trouble with booting can be due to the GRUB boot menu or a corrupt file in the /boot directory. Whatever the case may be, Boot Repair is an excellent software to help us start troubleshooting.
Plymouth is an application originally developed by Red Hat and later adopted basically by all the most commonly used Linux distributions. The software runs very early in the boot process, and provides eye-candy animations which accompany the user until he is prompted to login into the system. When Plymouth is used, boot messages are hidden, although they can be visualized simply by clicking the esc key. Some users, however, may prefer to visualize boot messages by default, and avoid any animation.
Checking the file system for errors is an important part of Linux system administration. It is a good troubleshooting step to perform when encountering bad performance on read and write times, or file system errors. In this tutorial, we will explain a procedure on how to force fsck to perform a file system check on the next system reboot or force file system check for any desired number of system reboots, whether it is the root or a non-root mount point.
LUKS (Linux Unified Key Setup) is the de facto standard encryption method used on Linux-based operating systems. As we saw in previous tutorials, when we want a partition or raw disk encrypted using LUKS to be automatically unlocked at boot, we need to enter a dedicated line into the /etc/crypttab file. Doing so, we are prompted to provide the encryption password interactively. This is quite straightforward on laptop or desktop machines, but how can we unlock a volume on an headless server? One solution is to use dropbear to get ssh access at an early boot stage, in the initramfs, in order to provide the volume password.
Samba is a free and open source interoperability suite of programs which allows us to share files and printers between machines running Linux or Windows. A Samba share is pretty easy to configure and can easily be accessed on clients, since the vast majority of Linux file explorers has built-in support samba. In certain situations, however, we may want to mount a Samba share at boot, just like a normal filesystem on a specified mountpoint.
The purpose of this tutorial is to show how to set kernel boot parameters in Linux. When a user boots their Linux system, the GRUB boot loader can set various parameters as it loads the Linux kernel. You can think of these parameters as arguments, the same type you are probably accustomed to using with commands in your terminal.
If you want to run Ubuntu 22.04 Jammy Jellyfish on your system but you already have Windows 10 installed and do not want to give it up completely, you have a couple of options.
One of the best ways to secure your Linux system is by setting a password in GRUB. By having a boot password, no one can boot into your system or access single user mode without supplying a password when the system first turns on.
Configuring a computer as dual boot system is a popular solution for users that wish to use Linux and Microsoft Windows on the same device. However, getting the two operating systems to share the same computer can be a bit tricky. In particular, Windows has its own boot loader and Linux uses GRUB. It’s easiest to have a dual boot system when GRUB is used as the boot loader, as it can be easily configured to boot into Windows as well as Linux.
In this guide, we’ll go through the step by step instructions to add Windows 10 to the GRUB menu. This way, you can select between Windows and your installed Linux distro when the computer first boots up. This guide assumes that you’ve already installed Linux and Windows on the same computer, and simply need to add Windows as an option to your GRUB menu.

A great feature of many Linux distributions is that you can create a live USB (or CD/DVD) key and boot directly into it. This allows you to try out an operating system, troubleshoot an existing installation, or install Linux onto the system’s hard drive.
Fedora is one of those distributions of Linux that allows us to boot into a usable environment directly from USB. In order to do that, we just need to write the Fedora installation file (.ISO format) to the USB thumb drive.
In this guide, we’ll go over the step by step instructions to create a Fedora bootable USB key via either command line or GUI. Follow along with us to get your USB key setup through Fedora’s Media Writer tool or the ddrescue command utility.

The root account, sometimes called super user, is the admin account on a Linux system, and is essential for performing all kinds of administrative tasks. You’ll need access to it in order to install or remove packages, manage other user accounts, and a lot more things. Anytime you access the root account, either through the su or sudo commands, you’ll be prompted for the root password.
If you have forgotten the password to your system’s root account, you don’t necessarily have to go back to square one and reinstall the whole operating system. It’s possible to recover and reset the root password, even without the old password. In this guide, we’ll take you through the step by step instructions of recovering a forgotten root password on Linux. This will work regardless of the Linux distribution you’re running, as long as its using the GRUB bootloader. Other bootloaders will have similar instructions.
