HELP! Problemi disco ed impossibilit' di accesso
Inviato: domenica 12 luglio 2009, 17:35
oggi proprio ad avviare il mio pc con Kubuntu 8.04 ma Grub mi da' error 18.
Penso ad un errore di grub [visto che fino a due ore prima il pc funzionava perfettamente]
Scarico la live di ubuntu da un secondo pc e parto con la live
provo a montare l'hd ma mi da' errore ed inizio a preoccuparmi.
Questo l'errore
wrong fs type, bad option, bad superblock on /dev/hda1,
missing codepage or helper program, or other error
In alcuni casi si possono trovare informazioni utili in syslog. Provare
ad esempio 'dmesg | tail'
questo l'output di dmesg e tail
e questi altri output interessanti
sapete aiutarmi? >:( >:(
