Salve a tutti, premetto che sono un principiante alle prese con Linux. Da Windows 7 ho cancellato la partizione Linux e anche quella swap lasciando intatto il volume C e quello riservato al sistema Windows. Al riavvio mi ha dato il noto problema "Windows Boot Manager: Avvio di Windows non riuscito...inserire il disco di installazione di windows" come se fosse rovinato il boot manager. Ho quindi avviato la live boot-repair secondo le istruzioni che ho trovato sul sito di ubuntu e nel tentativo di ripristinare il boot mi da questo problema http://paste.ubuntu.com/15373136/ che riporto qua sotto. Qualcuno sa darmi qualche indicazione

Dopo aver cancellato Ubuntu devi ripristinare il boot di Windows, come spiegato nella wiki con il tool apposito ms-sys.

Ciao, grazie. Ho seguito le istruzioni ma il problema persiste, al riavvio non riesco ad accedere a windows. cosa posso fare?

(13 Mar '16, 16:30) leonardoelia9 leonardoelia9's gravatar image

Sempre con l'errore di cui sopra?

Se sì, non è più un problema di Ubuntu. Devi probabilmente seguire le istruzioni che ti danno e mettere il disco di installazione :)

(13 Mar '16, 16:34) dadexix86 ♦♦ dadexix86's gravatar image

Si sempre con lo stesso errore

(13 Mar '16, 16:46) leonardoelia9 leonardoelia9's gravatar image

Usa il disco di installazione e segui le istruzioni che ti vengono date allora :)

(13 Mar '16, 17:44) dadexix86 ♦♦ dadexix86's gravatar image
