I can't think of anywhere to get that ISO, but just as a caution..do NOT put those disks in a drive again. Even a tiny crack in a disk can lead to shattering inside the drive as it spins up. And you'd almost certainly have to get a new drive.
Yes, I've heard and seen this.
Yup and thanks.. the disks have already been destroyed and trashed..
Btw, I found a legit copy w/ prod key and COA on Ebay for $17 shipped.
