Salut.

Aller un petit effort :

Peux-tu démarrer en mode Recovery (cmd+r lors du boot) et là dans le menu tu sélectionnes Utilitaires/Terminal.
Là tu tapes la commande :
diskutil list
et tu fais un copier des résultats.
Tu quittes le terminal puis dans le menu à 4 choix, tu cliques sur "Obtenir de l'aide"
Là tu ouvres un navigateur et tu peux te connecter au forum macg pour faire un coller du résultat ci-dessus, de préférence entre balises Code :
