I could not answer the" bootable CD with nero" that I had problem trying to use.
I do use successfully the "Norton System" bundle that includes the "ghost image backup" that works well.
After you create an image, save it on CD (or HD etc),
It boots from CD ( DOS GUI) Then follow easy to use options.Takes 2 or 3 cd's (one DVD).
and you can put your System back in 10 to 20 minutes un-attendant (or with more programs and files 20 to 35 min)
clean cut (hard drive been totally erased and only the image it is in).
