  1. Connect the USB Drive: Insert the bootable USB drive into the target computer.
  2. Access the Boot Menu: Restart the computer and press the designated key (usually F2, F10, F12, or Del) to access the boot menu. The specific key may vary depending on the computer manufacturer.
  3. Select the USB Drive: From the boot menu, choose the USB drive as the boot device.
  4. Follow On-Screen Instructions: The computer will now boot from the USB drive, and you can follow the on-screen instructions to install the operating system, run the utility, or explore the live environment.

IV. Troubleshooting Common Issues

  • UNetbootin Not Recognizing USB Drive: Ensure the USB drive is correctly connected and functioning properly. Try different USB ports or a different USB drive.
  • Distribution Not Booting: Verify that the downloaded ISO image is not corrupted. Try redownloading the image from a reliable source.
  • Slow Boot Process: The boot process can be slow if the USB drive is old or has a slow write speed. Consider using a faster USB 3.0 drive.
  • Errors During Installation: Check the integrity of the downloaded ISO image. Consult online forums or the distribution’s website for specific troubleshooting steps related to the chosen operating system.
  • Persistence Not Working: Ensure that the chosen distribution supports persistence. Check the UNetbootin settings and ensure that the persistence option is enabled.

V. Advanced Usage and Features

  • Using a Custom ISO Image: UNetbootin allows you to use your own downloaded ISO images. Select the “Diskimage” option and browse to the location of the ISO file on your computer.
  • Persistence Feature: For Linux distributions, the persistence feature allows you to save changes made within the live environment back to the USB drive. This is particularly useful for customizing the live environment or saving data between sessions. Be mindful of the space allocated for persistence, as it limits the available space for other files.
  • Remastering Distros: While not directly supported by UNetbootin, you can combine it with other tools to create customized distributions or add specific packages to existing ones.
