Не могу загрузиться в Ubuntu 16.04 после установки Ubuntu 18.04 (на отдельном разделе)

Question

У меня есть мультизагрузочная система с двумя жесткими дисками:

Windows и некоторые старые версии Ubuntu в /dev /sda
Ubuntu 16.04 на /dev /sdb1

Затем я установил Ubuntu 18.04 на пустой раздел /dev /sdb2. Я не помню, где находился старый загрузчик, поэтому я выбрал /dev /sdb для нового загрузчика.

Теперь я могу загрузить Ubuntu 18.04 без проблем, но при загрузке Ubuntu 16.04 я получаю следующее:

[   1.820371] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A

Я уже пробовал войти в режим восстановления и запустить sudo fsck -f /dev /sdb1, но безуспешно.

Как я могу это починить?

Поскольку я пытаюсь загрузить ту же ОС на том же оборудовании, что и раньше, я думаю, что моя проблема связана с новой версией или конфигурацией GRUB.

Проблема была в том, что /dev/sdb2 был отформатирован во время установки Ubuntu 18.04. Таким образом, его UUID изменился, и /etc/fstab больше не был корректным.

Мне пришлось загрузить Ubuntu 18.04, смонтировать /dev/sdb2 и обновить его UUID в /etc/fstab (смонтированного раздела).

UUID можно получить с помощью sudo blkid.

Угадайте: в Ubuntu 18.04 есть драйверы ядра, которые настраивают оборудование определенным образом, чего драйверы ядра в Ubunutu 16.04 не понимают или не учитывают при инициализации. Таким образом, если вы загружаете Ubuntu 16.04 после загрузки Ubuntu 18.04, то такое же базовое оборудование не работает должным образом, что приводит к этим ошибкам.

Диагностика: холодная загрузка Ubuntu 16.04 (выключите компьютер, отключите питание на несколько секунд) и проверьте, не исчезла ли проблема.

Обходной путь: Всегда холодная загрузка Ubuntu 16.04.
