Volume créé. Passe encore la commande (copier-coller à rebours) :
Bloc de code: 
asr restore --s / --t /Vol*/BOOT --erase --noprompt
  • la commande utilise l'exécutable Apple asr (apple_software_restore) > pour restaurer (= cloner en "mode blocs" absolu) le volume OS X Base System de l'OS de secours démarré (désigné par son point de montage /) => au volume BOOT. BOOT va être reformaté > renommé : OS X Base System comme la source > cloné d'un OS de secours de 1,3 Go > rendu démarrable à la fin par l'inscription d'un chemin de démarrage sur son en-tête. 2 passes : Restoring / Verifying > la progression en chacune marquée par tranches de 10%.

Poste le retour quand tu auras récupéré -bash-3.2# en signal de fin.
 
Voila le bon retour de la commande :

Parfait : feu vert pour la réinstallation ! -->

- dans la fenêtre des 4 Utilitaires macOS > lance l'option : "Réinstaller macOS" => et choisis Macintosh HD comme destination de l'installation lorsque cela te sera proposé.​

Merci pour ton aide en tout cas, je suis en train de ré-installer l'os.

Comment je devrais "supprimer la partition auxiliaire OS X Base System pour récupérer son espace au Conteneur qui aura été recréé."?
 
Une fois que tu auras ouvert ta session d'utilisateur > tu trouveras un terminal at: Applications > Utilitaires > Terminal.
