Ubuntu занимает слишком много времени в загрузке, как это исправить?

Question

У меня установлен Ubuntu 16.04 вдоль боковых окон. (Двойная загрузка)

Когда я установил Ubuntu, он загружался очень быстро, но теперь это занимает слишком много времени.

Это занимает 57 секунд.

Startup finished in 4.377s (firmware) + 4.664s (loader) + 3.718s (kernel) + 44.850s (userspace) = 57.610s

Что такое dev-sda7.device, которое занимает слишком много времени?

Вот результат работы cat /etc/fstab
