Back in 2004, I had bought the Norton Ghost 8.2 (or 9.0) and backed up my then newly bought desktop computer on to 3 DVDs. I recently bought Norton Ghost 12.0, after removing the older version. Following a Viral attack on this desktop, I now want to restore my computer to its original state (as in 2004). But I can't find the Ghost 8.2 or 9 Installation CD anywhere (I may have accidentlally thrown it away). I still have the backup DVDs with me, which is unreadable by Ghost 12.0. Could someone help by letting me know how I can restore my computer back to 2004 backup from the old backup.
