Naprawa Kali Linux Grub przy użyciu opcji Live CD nie działa

Próbowałem zainstalować Kali Linux, ale nie udało się to z powodu problemu z połączeniem internetowym . Następnie próbowałem naprawić plik grub przy użyciu opcji Live CD Kali Linux. Wykonałem wszystkie polecenia. Jednak nie widzę Kali Linux na liście systemów operacyjnych.

Czy coś robię źle?

Jeśli instalacja się nie powiedzie, po co jej szukać ... Często nieudana instalacja powoduje wycofanie zmian ...

Jeśli jednak instalacja zakończyła się powodzeniem, ale nie pojawiła się w GRUB-ie:
