Copyint a F15 install disk

[Geoffrey Leach]

I have a F15 install disk. I need to make a copy (don't ask :-).

This is how I proceeded.

1. Mount the DVD on /media/CDROM.
2. cp -r /media/CDROM/* /tmp/dvd
3. genisoimage -o /tmp/dvd.iso -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
-boot-info-table -input-charset iso-8859-1 -m TRANS.TBL -r /tmp/dvd
4. Replace source DVD with a blank DVD
5. growisofs -dvd-compat -Z /dev/dvd=$iso_file
6. On booting from the DVD and choosing "New install" the process skips 
the disk check menu and goes directly to the language choice.

The original DVD gives me the disk check option. I need to do that.

Any suggestions as to what step I've missed?

Thanks.
