Você pode tentar executar o script abaixo no LiveCD (possivelmente versões atualizadas no link). O script tenta automatizar parcialmente o processo para você. Ele foi escrito e testado para uma unidade NVMe, portanto, talvez seja necessário alterar um pouco as coisas se você estiver usando uma unidade SATA / IDE com um caminho /dev/sd* . Se você não estiver usando o EFI, poderá excluir qualquer linha contendo efi ou EFI executando sed -i -e '/efi/d' -e '/EFI/d' crypt-fix.sh após salvar o script no computador. Terá que adicionar alguma lógica de detecção para isso eventualmente.
