How To Reset Ubuntu to Factory Settings

Ubuntu 15

In this guide, we will walk you through the process of resetting Ubuntu to its factory settings. This process is particularly useful when you encounter problems that prevent you from logging in or using Ubuntu normally. Before we begin, it’s important to note that you should always back up your important files before attempting any system changes, as these methods can result in data loss.

Quick Answer

To reset Ubuntu to its factory settings, you have two options. First, you can try installing a new desktop environment, such as Xubuntu, Lubuntu, or Ubuntu MATE, which can often resolve login issues. If that doesn’t work or you want a fresh start, you can reinstall Ubuntu using a USB installer. Remember to back up your important files before attempting any system changes.

Installing a New Desktop Environment

If you’re experiencing login issues, one potential solution is to install a new desktop environment. This can often resolve login problems, and it’s relatively straightforward to do.

To install a new desktop environment, you’ll first need to open a terminal. You can do this by pressing Ctrl+Alt+F1. Once the terminal is open, you’ll need to run the following commands:

sudo apt-get update
sudo apt-get install xubuntu-desktop

The sudo apt-get update command updates your package lists to ensure that you’re installing the latest version of the desktop environment. The sudo apt-get install xubuntu-desktop command installs the Xubuntu desktop environment.

You can replace xubuntu-desktop with lubuntu-desktop or ubuntu-mate-desktop if you prefer those desktop environments. Once the new desktop environment is installed, you can try logging in again to see if the problem is resolved.

Reinstalling Ubuntu from a USB Installer

If installing a new desktop environment doesn’t resolve your problem, or if you simply want to start fresh, you can reinstall Ubuntu from a USB installer. This process involves downloading the Ubuntu ISO file and writing it to a USB drive.

To download the Ubuntu ISO file, open a terminal and run the following command:

wget http://releases.ubuntu.com/20.04/ubuntu-20.04.3-desktop-amd64.iso

This command downloads the Ubuntu 20.04.3 ISO file. You can replace 20.04 with the version you want to download.

Once the ISO file is downloaded, you can write it to a USB drive using the ddrescue command. To do this, run the following commands:

sudo apt-get install gddrescue
sudo ddrescue -d -D --force ubuntu-20.04.3-desktop-amd64.iso /dev/sdX

The sudo apt-get install gddrescue command installs the ddrescue utility, which is used to write the ISO file to the USB drive. The sudo ddrescue -d -D --force ubuntu-20.04.3-desktop-amd64.iso /dev/sdX command writes the ISO file to the USB drive.

In this command, /dev/sdX should be replaced with the correct device name for your USB drive. Be sure to select the correct device, as this command will overwrite the contents of the USB drive.

Once the ISO file is written to the USB drive, you can use it to reinstall Ubuntu. This will reset Ubuntu to its factory settings.

Conclusion

Resetting Ubuntu to its factory settings can be a useful troubleshooting step when you’re experiencing problems. Whether you choose to install a new desktop environment or reinstall Ubuntu from a USB installer, it’s important to always back up your important files first. With these steps, you should be able to reset Ubuntu and get back to using it normally.

Can I reset Ubuntu to factory settings without losing my files?

No, resetting Ubuntu to factory settings will erase all your files and settings. It’s important to back up your important files before attempting the reset.

How long does it take to reinstall Ubuntu from a USB installer?

The time it takes to reinstall Ubuntu from a USB installer can vary depending on your computer’s hardware and the speed of your USB drive. Generally, it can take anywhere from 30 minutes to an hour.

Can I choose a different version of Ubuntu to reinstall?

Yes, you can choose a different version of Ubuntu to reinstall. When downloading the Ubuntu ISO file, make sure to replace "20.04" in the command with the version you want to download.

Will reinstalling Ubuntu remove all the installed applications?

Yes, reinstalling Ubuntu will remove all the installed applications. You will need to reinstall them after the reset.

Can I reinstall Ubuntu from a DVD instead of a USB drive?

Yes, you can reinstall Ubuntu from a DVD instead of a USB drive. Instead of using the ddrescue command, you will need to burn the ISO file to a DVD using appropriate burning software.

What should I do if I encounter errors during the reinstallation process?

If you encounter errors during the reinstallation process, it’s recommended to check the integrity of the downloaded ISO file and the USB drive. You can also try using a different USB drive or downloading the ISO file again.
