Eu consertei. Parece que meu grub2 voltou ao grub. Reinstalado o grub2 e o kernel foi encontrado. De volta ao kernel 3.2.0-30
Eu estraguei um pouco. Esperando que alguns aqui possam me ajudar.
Eu tentei instalar o mais novo catalisador 12.8. Infelizmente, isso quebrou meu sistema. Eu estava preso no modo gráfico baixo. Eu finalmente consegui restaurar os drivers proprietários e entrar no Ubuntu novamente. Mas agora estou preso no kernel 3.2.0.26. Eu tinha instalado o kernel 3.2.0-30, mas o sistema não o vê mais. Eu tenho o kernel 3.2.0-29 também, mas o sistema não pode ver isso também. No menu do grub. Quando eu uso sudo update-grub , eles são listados.
Aqui está a saída que recebo:
Searching for GRUB installation directory ... found: /boot/grub
Cannot determine root device. Assuming /dev/hda1
This error is probably caused by an invalid /etc/fstab
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
Searching for splash image ... none found, skipping ...
Found kernel: /boot/vmlinuz-3.2.0-30-generic
Found kernel: /boot/vmlinuz-3.2.0-29-generic
Found kernel: /boot/vmlinuz-3.2.0-27-generic
Found kernel: /boot/vmlinuz-3.2.0-26-generic
Found GRUB 2: /boot/grub/core.img
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done
Eu procurei em todos os lugares para encontrar uma solução para o meu problema, mas não consigo encontrar nenhuma solução.
Se você precisar de qualquer saída de log para descobrir o problema, por favor, deixe-me saber quais.
Atualização: aqui está a saída para o grub.cfg

Como posso definir o kernel 3.2.0.30 como o kernel padrão? De acordo com este arquivo, o kernel 3.2.0-30 não existe.
Eu consertei. Parece que meu grub2 voltou ao grub. Reinstalado o grub2 e o kernel foi encontrado. De volta ao kernel 3.2.0-30
