I've copied livecd.sqfs and the contents of isolinux from PCLinuxOS Gnome live cd to my flash drive and renamed isolinux.cfg to syslinux.cfg and installed syslinux on it. After I try to boot, there is a message that says

"Error: Unable to mount loop filesystem

Commands were:
losetup /dev/loop0 initrd/cdrom/livecd.sqfs
mount -r -t squashfs /dev/loop0 initrd loopfs
Most likely cause is bad burn or bad download
Please run media check on livecd

Dropping you to a limited shell."

Do I have to modify the boot options?
The ISO Image worked properly in VMware Player
Thank You
