Reinstalling Ubuntu from the Terminal can seem daunting, but it’s a straightforward process once you know the steps. Whether you’re looking to start fresh or fix an issue with your current system, reinstalling can be the quickest route to a clean slate. The following guide will walk you through the necessary steps to reinstall Ubuntu using the Terminal, ensuring that you can get back to a fully functioning system in no time.
Step by Step Tutorial: Reinstalling Ubuntu from the Terminal
Reinstalling Ubuntu from the Terminal involves a series of commands that will remove your current installation and replace it with a fresh one. Before proceeding, make sure you have backed up any important data.
Step 1: Boot into Recovery Mode
First, you’ll need to boot into Recovery Mode to access the Terminal.
Booting into Recovery Mode involves restarting your computer and holding down the Shift key (or sometimes the Esc key) as it boots up. This will bring up the GRUB menu, where you can select the ‘Advanced options for Ubuntu’ and then choose ‘Recovery mode.’
Step 2: Open a Terminal Window
From the Recovery Mode menu, select ‘root’ to open a Terminal window with root access.
In Recovery Mode, you’ll see a menu with several options. The ‘root’ option drops you into a Terminal session where you have full access to run commands as the root user, which is necessary for reinstalling the system.
Step 3: Reinstall Ubuntu
Use the command apt-get install --reinstall ubuntu-desktop to reinstall the Ubuntu desktop system.
This command tells the package manager to reinstall the ‘ubuntu-desktop’ package, which is essentially the entire Ubuntu desktop system. This process might take a while as it downloads and installs all the necessary files.
Step 4: Reboot the System
Once the installation is complete, type reboot and press Enter to restart your computer and boot into your fresh Ubuntu installation.
After the installation, a reboot is necessary to start using the newly installed system. Your computer should now boot up as if it were a new installation, with all default settings restored.
After completing these steps, your computer will restart and you’ll be greeted with a fresh installation of Ubuntu. All previous configurations and user data will have been wiped clean, so you can start customizing your system from scratch.

- Reinstalling the system will remove any third-party software you’ve installed, so you’ll need to reinstall these programs afterward.
