Fixing Manjaro Linux Boot Problems: A Recovery Guide

A step-by-step guide to recover and fix a non-booting Manjaro Linux system after updates

Boot issues in Manjaro Linux often occur after system updates, especially when kernel or bootloader packages are updated. This comprehensive guide will walk you through the recovery process step-by-step, helping you get your system back up and running.

Prerequisites

Before starting the recovery process, you'll need:

  • A Manjaro Linux live USB/DVD (use the same version as your installed system if possible)
  • Basic knowledge of terminal commands
  • Access to your system's root password (if set)

Step 1: Boot from the Live USB/DVD

  1. Insert your Manjaro Linux live USB or DVD
  2. Restart your computer
  3. Access your BIOS/UEFI boot menu (usually by pressing F12, F11, or Esc during startup)
  4. Select the USB drive or DVD to boot from
  5. Choose "Boot Manjaro Linux" from the boot menu (not the installer option)
  6. Wait for the live environment to fully load

Step 2: Identify Your Manjaro Partition

First, you need to identify which partition contains your Manjaro installation:

Bash

Note down the partition that contains your Manjaro installation (e.g., /dev/sda2, /dev/nvme0n1p3, etc.).

Step 3: Mount Your Manjaro System

Now you'll mount your Manjaro partition and prepare to chroot into it:

Bash

Step 4: Prepare the chroot Environment

Before entering the chroot environment, mount the necessary system directories:

Step 5: Enter the chroot Environment

Now you can enter your installed Manjaro system through chroot:

Step 7: Exit and Reboot
