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

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 [ 1.820395] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun [ 2.023723] usb 2-1.6: string descriptor 0 read error: -22 ssd1: clean, ... files, ... blocks [ 5.074685] usb 2-1.6: string descriptor 0 read error: -22 Welcome to emergency mode! After logging in, ... 

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.
