Buffer I/o error, dev sdb, logical block

Messaggioda domenico72 » domenica 20 gennaio 2019, 17:23

Non riesco ad accedere al mio Ubuntu 14.04. anche attraverso la procedura di ripristino dal grub. Il messaggio d'errore, dopo una lunga attesa e quello in oggetto. Specifico che nel mio pc sono installati due sistemi operativi, windows vista ed ubuntu. Ho il cd live ma non so come procede. Aiuto :muro:

Colpa mia, non pensavo avessi centrato il problema quindi ho preferito creare una nuova discussione postando il codice di errore e un listato, per indicare in che condizioni mi trovo.
