Recuperando Instalação do Ubuntu

Ubuntu 8.04.1

Para recuperar uma instalação que não aparece no Grub, mas que está numa determinada partição (ex: sda3) do HD, reinicie o computador a partir do live CD.

Usando o Terminal como root:

• mkdir /mnt/linuxtorecover
• mount -t ext3 -o rw /dev/sda3 /mnt/linuxtorecover

(*) As instruções abaixo não se aplicam ao GRUBv2 (Ubuntu 9.10 ou superior), nestes casos ver links mais abaixo.

Confira as informações do arquivo /mnt/linuxtorecover/boot/grub/menu.lst para ter certeza que está apontando para a partição correta.

• mkdir /home/ubuntu/root
  
• mount -t ext3 -o rw /dev/sda3 /
  
• mount -t ext3 -o rw /dev/sda3 /home/ubuntu/root
  
• cp -R /home/ubuntu/root/boot/grub /boot
  

Reinstalar o grub.

• /home/ubuntu/root/sbin/grub-install /dev/sda

sda indica o primeiro HD (sdb é o segundo...), e sda3 é a partição onde o linux está instalado nesse HD.
