  • Open a terminal window.
  • Type sudo rm -rf /etc/ and press Enter.
  • This will delete the Linux system configuration files.

Step 7: Remove the Linux System Libraries

After removing the system configuration files, you need to remove the system libraries.

• Remove the Linux system libraries:

  • Open a terminal window.
  • Type sudo rm -rf /usr/lib/ and press Enter.
  • This will delete the Linux system libraries.

Step 8: Remove the Linux System Packages

After removing the system libraries, you need to remove the system packages.

• Remove the Linux system packages:

  • Open a terminal window.
  • Type sudo apt-get autoremove -y and press Enter.
  • This will remove the Linux system packages.

Step 9: Reboot the System

Once you have removed the Linux operating system, you need to reboot the system.
