[AIUTO] Problema accesso partizione bootcamp

[torquato]

Ciao,

ho un grosso problema col mio macbook air. L'HD da 120gb partizionato in 40gb con snowleopard ed 80gb bootcamp con windows7. Windows non si avvia più, rileva una corruzione del boot record. Il disco viene correttamente visto e montato invece da leopard. Ho provato con ubuntu remix rescue e l'utility disktest ma credo di aver peggiorato le cose, ora la partizione bootcamp non viene più nemmeno montata su leopard.

Questa è la situazione attuale:

Problem: partition 3 is too big for the disk.

Aborting write operation!

Aborting write of new partition table.

Scusate per la lunghezza del post ma ho cercato di fornire più informazioni che potevo, ora vorrei evitare di fare altri tentativi

ci sono dati abbastanza importanti sulla partizione windows che vorrei recuperare.

Grazie!
