Norton Ghost 8.2 Boot Disk

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.

They are .GHO files.

OK. Then they were not created by Ghost 9. But they can be restored by Ghosts 9 and 10 as well as Ghosts 8.* and 11.*

Actually, I just found out that, the first of the 3 backup DVDs is a Self-Bootable DVD and the first thing it does is, it boots up the PC using PC-DOS and shows how to restore the data to the appropriate partition.  I also found out that the backup was created using Ghost 2003 and not Ghost 8.2 (as mentioned ealier).  Because of this, I was able to restore my Desktop to my September 2004 backup.

 

Thanks anyways.
