Lubuntu
Hello, you can download Lubuntu from its official website. For A) installing, no purchase is needed—just follow the installation instructions. For B) booting from a USB, use a reliable USB image and ensure your system meets the requirements beforehand.
Download the installation from a USB drive and follow the instructions provided.
Make sure you're referring to a USB drive, not a USB port. If you're downloading from the internet, you'll need to transfer the file to the USB before installation.
You can also utilize unetbootin, which offers numerous distributions in its selections. Simply select, click, and it will automatically download and install the chosen Linux distribution onto your USB drive. Alternatively, you can pick your preferred ISO file directly.
If you want to transfer it to an external hard drive, the steps are similar but not identical. Rufus isn’t compatible with external drives, so you’ll need a different tool or method.
