Eu recentemente instalei o Ubuntu no meu sistema, e como minha instalação anterior do grub2 era confusa, decidi reinstalar o grub2 nessa partição do Ubuntu.
De qualquer forma, não funcionou totalmente: o grub-install não deu nenhum erro, ainda que na reinicialização, o grub não mostre seu menu, mas apenas sua linha de comando.
Eu consigo inicializar todos os sistemas operacionais no meu computador, mas é algo que eu gostaria de evitar a longo prazo (digitar 4 linhas de código, com um mapa de teclado americano é um pouco mais lento do que rolar para uma entrada específica ).
Eu tentei várias configurações do GRUB_TERMINAL, mas não obtive nenhuma alteração.
Não há nenhuma mensagem de erro que eu possa ver antes do prompt de linha de comando, somente a mensagem de introdução do comando grub.
Aqui está meu /boot/grub/grub.cfg

Existe alguma parte do processo de configuração que eu perdi? O Grub sempre trabalhou fora da caixa no passado, pelo menos quando instalado no Ubuntu, o que é altamente possível.
Agradecemos antecipadamente
Editar: Usando o aptitude para baixar novamente e reinstalar o grub corrigiu o problema agora. Mas ainda assim gostaria de saber o que estava causando o problema.
