salve,<BR>
ho avuto anch'io un problema simile con il grub quando avevo Ubuntu Dapper.<BR>
L'ho risolto installando e facendo girare Super Grub<BR>
(<A HREF="http://supergrub.forjamari.linex.org/">http://supergrub.forjamari.linex.org/</A> ), dopo aver masterizzato il cdrom dall'iso scaricato dal sito.<BR>
Spero che possa essere utile anche a te.<BR>
