This is how to solve this problem : ( If someone else has the same problem! ) 

    public ActionResult DeleteConfirmed(int id)
  {
    Var a = db. Pages.Where(p => p.PageGroup == id).ToList(); 

     foreach (var item in a) 

        { 
           System.Io.File.Delete(Server.MapPath("/images/" + item.ImageName));
        }

           var d = db.PageGroups.Find(id);
           db.PageGroups.Remove(d);
           db.SaveChanges();

           return RedirectToAction("Index");
      }
