Nero problem

I recently purchaed a HP dvd burner which came with Nero backitup software.
I proceeded to backup my hard drive and everything has worked fine ( I thought). After replacing the hard drive I attempted to restore with Backitup and the program requires an *.nbi file which is not on the disks that I used to backup the drive. There are dat files and some msg files but no nbi files. Can someone tell me what I am doing wrong?

I am running XP.


Nero did that to me too, and it seems to be a fairly common problem.
You can copy and paste the files manually from the CD, and if Nero split any files, there are a couple posts in the Nero software section on how to join them again.
Best of luck.
