i installed vista and XP on my system to have dual boot but the Xp was not booting as the ntldr boot loader will not be found. i then deleted the XP from the partition i put it in but even after deleting it, anytime i boot my system the XP and Vista all will appear as boot options though the Vista is the default. now i want to remove the XP completely from the system and not to appear as a boot option. what can i do to achieve this.
