Kernel Panic - não está sendo sincronizado: VFS Não é possível montar Root está em bloco desconhecido (0,0)

1

Recebi um erro Kernel Panic após atualizar o servidor Ubuntu. Depois de passar o menu do GRUB, recebi o seguinte erro.

Eu tenho hospedado um mediawiki nesse servidor que não está armazenado em backup. Eu não quero perder esses dados.

Eu reparo chuva de inicialização, mas não ajudou   link

Eu tentei aplicar a correção em postagem 41930 e tive problemas.

Então os problemas começaram ...

O que devo tentar em seguida?
