Re: booting iso image having syslinux
It could be easier to use the partedmagic live iso, pmagic-4.3.iso, (kernel 2.6.30.1-pmagic), which does loop mount iso with 64 bit grub.efi loopback on Apple mac (It has gparted).

Thanks but it seems pmagic is much more than a partitioning tool. In that case I can use puppy linux. Though my aim is to collect little live iso tools in usb stick.

The kernel path is correct. But after getting your response, I have
downloaded the iso again and overwrite the existing one in usb-stick.
Also check the md5sum and it is correct. And something *NEW* has
happend this time. No more error like before ( invalid magic number )

Try loading the kernel with the old linux loader with linux16 and
