installazione 9.04 e problemi cin grub

[fabrica74]

Sono passato dalla versione 8.04 alla 9.04, al successivo avvio, ubuntu non si avvia perchè mi da errore su grub (read error 21). Ho ripristinato grub e ubuntu mi si è avviato correttamente ma con la versione 8.04. Come faccio a modificare il grub per avviare la versione 9.04?

Ciao e grazie anticipatamente

Tu hai 2 dischi e due installazioni di Linux, cosa hai nel disco da 80 e cosa in quello da 300 ?

[fabrica74]

Il disco da 80 è l'hard disk del pc, dove avevo intenzione di installare la versione 9.04, il disco da 300 è un disco esterno, dove ho backup, foto ecc...

[patel]

il disco da 300 è un disco esterno, dove ho backup, foto ecc...
