Проблемы ядра Linux: Ubuntu16.04 не может загружаться

Недавно я обновился с ubuntu 14.04 до 16.04. Я арендую выделенный сервер, тогда я не могу получить доступ к GRUB при запуске. Поэтому я не могу загрузиться (нет ответа на пинг), и я не знаю, почему. Мой хост позволяет загружать с живым CD-образов (ubuntu 12.04) для восстановления моего сервера, затем я смонтировал свои разделы и начал сессию chroot. Я попытался установить последний linux-образ (4.4.0-47), и установка работала как шарм. Я выполнил команду update-grub.

Вот /boot/grub/menu.list

Я также попытался установить еще одну версию ядра, как вы можете видеть (4.4.0-34 ).

Другая информация: похоже, что журналы новостей не записываются при загрузке ubuntu16.04 (например, Syslog или dmesg). Я знаю, потому что я сделал команду «ls -t -lh» в / var / log для сортировки файлов по времени. Мой последний dsmeg до обновления.

Можете ли вы помочь мне решить эту проблему с загрузкой? Спасибо за вашу помощь. Задайте мне информацию
