How to reset the Ubuntu system?

To reset the Ubuntu system, you can follow these steps:

1. Backup important data: Make sure to save important files and data to an external storage device or cloud storage before performing the reset to prevent any loss.

2. Creating Ubuntu installation media: Download the latest version of the Ubuntu ISO file and burn it onto a DVD or create a bootable USB installation device.

3. Start the computer: Insert the Ubuntu installation media into the computer, then restart the computer. Ensure that the computer boots from the installation media.

4. Choose installation option: On the Ubuntu installation interface, select either “Install Ubuntu” or “Try Ubuntu without installing” depending on whether you want to reinstall the system or try the new system first.

Follow the installation wizard: choose the appropriate options such as language, time zone, and keyboard layout according to the prompts on the screen.

6. Choose the partition option: In the partition options, select the “Erase disk and install Ubuntu” option to completely wipe and reinstall the Ubuntu system. If you only want to reset the system without erasing the data on the hard drive, you can choose other appropriate partition options.

7. Create a new username and password during the installation process, which will be used to log into the newly installed Ubuntu system.

8. Installation complete: Wait for the installation process to finish and follow the on-screen prompts to restart the computer.

Once the reset process is complete, your Ubuntu system will be restored to its initial state, allowing you to reconfigure and use it again. Remember to reinstall any necessary software and restore your backup files.
