O Grub não inicializa o Linux automaticamente, mas a edição da linha de comando funciona

Question

Eu tenho 2 discos rígidos no meu computador. No primeiro instalei o Windows 7 com Linux (Ubuntu) - com diferentes partições.

No começo da inicialização, eu tinha a opção para escolher Linux / Windows .

Mas agora, tenho um problema com o GRUB. Ao iniciar, eu tenho esta tela .
Consegui carregar o Linux com a linha de comando, que carrega o kernel manualmente.

Parece que tenho um problema com o arquivo grub.cfg .

Qual é a melhor maneira de corrigir grub.cfg ? Para que, ao inicializar, eu tenha a opção de escolher o Linux / Windows 7 como antes.

Em seguida, clique em "Opções avançadas", vá até a guia "Localização do GRUB" e selecione a partição em que o GRUB está. Em seguida, clique em Aplicar. Você configurou o firmware UEFI ou BIOS (Legacy BIOS) ativado?
