grub rescue с lvm без файловой системы
Я пытался спасти Grub, но не смог его исправить, если я использую ls в grubrescue, и при выборе любого из них (также (hd0,1)) всегда возникает ошибка, сообщающая об отсутствии файловой системы
Система представляет собой Ubuntu 18.04 x64, работающую на виртуальной коробке, разделенные файлы .vmdk. Также пытался смонтировать с помощью компакт-диска Ubuntu Live и смонтировать раздел, но он пуст
Я наблюдал и пробовал разные вещи с других форумов. но ничего не помогло, я также использовал диск восстановления загрузчика и вывод следующий, и я не знаю, что делать, знаю
