Two paths are wrong in the bullet list that goes below the paragraph that starts with "Now, we are going invoke the Drupal installation process...".
First correction:
The sites/all/settings.php file configured and pointing to a database Has the wrong path.
It should be "default" instead of "all" so it would be: The sites/default/settings.php file configured and pointing to a database
Second correction:
The sites/all/files directory ready to be used by the website has the same mistake.
It should be: The sites/default/files directory ready to be used by the website
