Ho avuto la malsana idea ( :-\ ) di effettuare l'upgrade in oggetto dall'installatore interno di Ubuntu invece che tramite ISO, ovviamente e' andato tutto a putt.... ehm ci siamo capiti.
Il problema e' comune a molte persone, ovvero all'inizio l'avvio sembra procedere normalmente, e poi il sistema va in crash dando un messaggio di errore sull'uuid dell'hard disk, che evidentemente e' sbagliato in qualche modo. Ho provato a risolvere utilizzando i consigli contenuti in questo ed altri forum, che tra gli altri comprendono:
1) usare il comando

sudo vol_id /dev/hdc12) provare con un
Codice: Seleziona tutto
sudo update grub3) cercare su /dev/disk/by-uuid se c'e' un uuid diverso dal precedente, ma questo file nel mio sistema non esiste, mentre nel ramdisk del live CD contiene due link:

Faccio presente che avevo gia' notato in passato che ubuntu, non so perche', mi rilevava un unico disco sata nel sistema, mentre io ho un unico disco ide, e quindi direi che il problema potrebbe essere che, aggiornando, Hardy Heron si sia accorta dell'errore, lo abbia corretto, ma si sia poi dimenticata di aggiornare un qualche file di configurazione di sistema.
Che fare?
