Как зафиксировать, когда личинка больше не монтирует раздел начальной загрузки при запуске?

Эта система имеет раздел начальной загрузки на устройстве dm-набега.

Я обновил систему стандартными методами от более старой Ubuntu до последнего LTS. Теперь, если ядро обновляется "Кв. - получают обновление", новое ядро не загрузится. И при этом записи не перечислены на экране начальной загрузки GRUB.

Я решил, что личинка обновления работает, как я ожидал бы, обновляя раздел, смонтированный при начальной загрузке/. Однако, когда я загружаю его, GRUB читает корневой диск / папка начальной загрузки. Это не монтирует набег isw_dbbbejgeca_Volume0p1 к начальной загрузке / перед запуском.

Если я скопирую содержание смонтированного / загрузочного диска к папке, то размонтирую его и скопирую все содержание в корневой диск / папка начальной загрузки, то система затем загрузит новые ядра и покажет все обновления в меню GRUB.

Я нуждаюсь в помощи, чтобы удостовериться, что GRUB смонтирует основанный на набеге раздел начальной загрузки.

Затем некоторый вывод от инструмента восстановления начальной загрузки.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge 
(in order to enable-raid enable-lvm) and reinstall the 
grub2 of mapper/server01-root into the MBR of sdb, using 
the following options:
        mapper/isw_dbbbejgeca_Volume0p1/boot,
The boot flag would be placed on sdc1.
Additional repair would be performed:
        unhide-bootmenu-10s


=================== Advice in case of suggested repair
Warning: continuing without internet would leave your system 
unbootable. Please connect internet.
Do you want to continue?


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdb (128GB) disk!


=================== User settings
The settings chosen by the user will not act on the boot.

Я не уверен в предложениях.

The boot flag would be placed on sdc1.

sdc1 является диском с резервной копией, это не будет там всегда. Мне не нужна установка начальной загрузки на том диске I, думают.

Я волнуюсь, что это может стать незагрузочным. Это восстановление начальной загрузки требует Интернета, но тот сервер не будет получать доступ к Интернету.

Так, я прошу, чтобы Вы совместно использовали некоторые команды личинки, чтобы сделать другие шаги:

 purge and reinstall the grub2 of mapper/server01-root into the MBR of sdb, using the following options:
    mapper/isw_dbbbejgeca_Volume0p1/boot,
 Additional repair would be performed:
    unhide-bootmenu-10s
