I did remasting the knoppix on last week.when I finished the work . burned the file of iso to CD.
I reboot pc ,modified the bios system---boot sequence ,boot from CDROM,but failed.The output messages is "Disk Boot failure,insert system disk and press enter".

why? How can I do?help me.

I used the command--- mkisofs as this:

mkisofs -pad -I -r -J -v -V "xxxx" -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -o /mnt/hda10/myknoppix.iso /mnt/hda11/myknoppix
