Boa tarde pessoal.Estou com um notebook que não inicia o ubuntu.
Tentei ir pelo modo mais fácil, fazer um backup com live cd e depois formatar, mas o problema é que quando entro com o live cd para fazer o backup, não encontro a pasta home. E nesse caso é muito importante o backup.
Pesquisei em vários fóruns sobre o problema mas não consegui resolver.
O primeiro erro que apresentou, era uma tela preta (tipo terminal), onde aparecia erro que não foi encontrado o arquivo normal.mod )aparecia o caminho desse arquivo, mas não lembro qual é) e logo abaixo aparecia "grub rescue>"
Depois consegui fazer uns processos de uns tutoriais e agora aparece a mesma tela preta, só que aparece escrito diferente: "GNU GRUB version 2.04 Minimal BASH'like line editing is suported. For the fist word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions." e logo abaixo: "grub>"
Fiz outros passos seguindo outros tutoriais nessa etapa, mas sem sucesso. quando digito "exit" nessa tela, parece que o notebook tenta iniciar, porém me parece que é pela placa de rede e não pelo HD, como está configurado na BIOS.
Utilizei o programa Boot Repair usando um live cd do ubuntu que gerou o relatório abaixo:
