CI's main index.php sets the paths of the system and application folders. If you are including index.php from another directory, these paths are set relative to your "including" directory.

Try changing the following lines in index.php

$system_path = 'system';
// change to...
$system_path = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'system';

// and...
$application_folder = 'application';
// change to...
$application_folder = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'application';

The dirname(__FILE__) will give you the absolute path of the index.php even if you include it somewhere else.

The problem with loading codeigniter from external file outside codeigniter installation is solved using the first answer which I marked as accepted. And the problem with calling default controller/method was resolved using constant (define). Here is the updated code for external.php file:

<?php
// Remove the query string
$_SERVER['QUERY_STRING'] = '';
// Include the codeigniter framework
define("REQUEST", "external");
ob_start();
require('./new/index.php');
ob_end_clean();
?>

And here is the default controller method:

public function index($flag = NULL) 
 {
  if (constant("REQUEST") != "external")
  {
    // some code here
  }
 }
