Ho cercato invano il Q & A correlato per risolvere il mio problema, quindi lo postò qui:
Sono in esecuzione El Capitan con Windows 10 in fase di boot, ho modificato la partizione di Mac OS X e ridotto le sue dimensioni di 160 GB. Da allora non riesco ad avviarlo automaticamente (nessuna schermata di avvio del dispositivo avviabile) e non riesco ad avviare la partizione di Windows.
La mia intenzione era quella di ridimensionare la partizione di Mac OS e darla a Windows tramite un'app di Windows chiamata procedura guidata minitool, ma sono rimasto bloccato nel primo passaggio. Anche se ora riesco a unire lo spazio libero alla partizione di MAC OS e lasciare tutto così com'ero, sarei anche felice.
Posso ancora vedere i file bootcamp tramite Finder e nell'app Startup Disk posso vedere sia Bootcamp che Mac OS X, ma non riesco a selezionarne uno.
Ecco altre informazioni:
