Damaged install disk

[Peter Smith]

Hello,

I scratched my RH 7.3 install disk 2.
I was able to copy out most files, and recovered all the missing files from
the web, so I burned a replacement disk.
When I used the disk, the installer rejected it as "Not a Red Hat disk".
Is there any way around this?

We have RH 8.0 disks, but I really need to recreate the 7.3 system for
complicated reasons we don't have time to go into.

Thanks in advance,
Peter Smith
