failed installation of system

I am trying to install CLD KDE I686
but it fails saying
“Failed to copy files from /mnt/livecd.kBa6eBJD to /mnt/install”.

CLD KDE 13 I386

Was installation from CDROM or Flash?

CDROM

Do you check CD?
Try to copy livecd.squashfs from CDROM.

Copy it to /mnt/install on hard disk?

What do I do next?

It failed to copy to /media/CLD-13/

Probably disc is burned with an error. Try to burn other CD or write image on flash.
