would take u longer to make the query as u need to make a different name for each forum section and permissions for each
but here are two querys to get you started

Main section

INSERT INTO `forum` VALUES ('1', '0', 'Main Category', 'Main Category', 'Main Category Description', 'Main Category Description', '86017', '0', '1', '0', '0', '', '0', '', '0', '0', '', '0', '-1', '', '', '-1', '1,-1', '', '', '1,2,-1', 'lastpost', 'desc', '');

Forum inside main section

INSERT INTO `forum` VALUES ('2', '0', 'Main Forum', 'Main Forum', 'Main Forum Description', 'Main Forum Description', '89799', '0', '1', '0', '0', '', '0', '', '0', '0', '', '0', '-1', '', '', '1', '2,1,-1', '', '', '2,-1', 'lastpost', 'desc', '');

This is only a guide
