To fetch a type of entity you have to add the entity_type condition to it.

You have to fetch nodes, so the code for it will be as follows:

    $query = new EntityFieldQuery();
    $query->entityCondition('entity_type', 'node');

The entity condition is set using the function **entityCondition** in which you can set the entity type as node. Once you have set the entity condition, you can execute the query. The **node ids** are returned in an array in the node key of the result. The complete code to display the nodes will be as follows:

    $query = new EntityFieldQuery();
        $query
        ->entityCondition('entity_type', 'node');
    
    
        $result = $query->execute();
        $nodes = array();
        if (isset($result['node'])) {
          $nids = array_keys($result['node']);
          $nodes = node_load_multiple($nids);
        }
    
        $list = array();
        foreach ($nodes as $node) {
          $options = array('absolute' => TRUE);
          $url = url('node/' . $node->nid, $options);
          $list[] = '<a href='.$url.'>'.$node->title.'</a>';
        }
    
        $theme_args = array('items' => $list, 'type' => 'ol');
        $content = theme('item_list', $theme_args);
    
        $block = array(
          'subject' => t('A block to display results from entityquery'),
          'content' => $content,
        );
        return $block;

Thank you.
