GRUB не стартовая система по умолчанию

Моя система не загружается, пока я не нажимаю, вводят в личинку.

Почему не GRUB_TIMEOUT установка работы? Я имею, работал update-grub и Личинка Customizer, но ничто не помогает. Мой os-prober также не работает. Они оба работали, когда я был на 14,04, теперь я использую 14.10.
