У меня есть сервер Ubuntu 14.0.4. Цель состоит в том, чтобы кикстарт установил 2 установки Ubuntu бок о бок с двойной загрузкой.
Ubuntu установлен нормально на sdaX
. Я использовал dd
для клонирования этого в sdaY
. Я изменил UUID, fstab
и могу даже загрузиться в sdaX
и просмотреть содержимое sdaY
. Однако, когда я пытаюсь загрузиться в sdaY
я получаю /sbin/init No such file or directory
и паника ядра.
Я отредактировал grub, чтобы убедиться, что он смотрит на sdaY
.
Может кто-нибудь придумать, что я пропустил, чтобы сделать этот раздел загрузочным. Если это не удастся, любой способ восстановить установку Ubuntu с помощью командной строки.
Примечание: и fdisk -l sda1
и sda5
говорят, что таблица разделов не найдена.
