Estou muito perdida. Eu fiz uma nova instalação do Ubuntu 10.04 em um laptop. Primeira reinicialização foi bem. Eu corri todos os upgrades recomendados, e agora toda vez que eu começo eu recebo apenas um
grub>_
prompt. Nenhuma mensagem de erro, apenas o prompt, e um pequeno banner no topo dizendo a versão do grub e me dizendo que tenho uma edição mínima do estilo bash. Eu tentei:
1) Reinstalando o grub via
sudo grub-install sda
(Existe apenas um disco com apenas duas partições, uma primária e outra para swap)
2) Alterado
GRUB_HIDDEN_TIMEOUT=10
GRUB_TIMEOUT=30
GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=90"
GRUB_CMDLINE_LINUX="rootdelay=90"
em / etc / default / grub. Sem sorte. Eu posso inicializar com o seguinte:
grub> set root=(hd0,1)
grub> probe (hd0,1) -u
c00fadde-f7e8-45e7-a4da-0235605f756
grub> linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235605f756 rootdelay=90
grub> initrd /boot/initrd.img-2.6.32-21-generic
grub> boot
E então tudo parece estar bem a partir daí. No prompt do grub, se eu tentar
configfile /boot/grub/grub.cfg
A tela é limpa e recebo outro grub > prompt.
Então, sério, qual poderia ser o problema?
