can grub boot isolinux.bin file ?

[J. Bakshi]

Hello list,

I am trying to boot acronics true image .iso from grub. The .iso has inbuilt 
syslinux.
After mounting the .iso with loopback I get a folder called isolinux and within
that I get the following

boot.cat      isolinux.bin  kernel.dat    spl.lss
bootmsg.txt   isolinux.cfg  ramdisk.da

To call the syslinux , I have added the following in the grub.cfg

menuentry "Acronics" {
set isofile="/ATIBCD2010E.iso"
loopback loop $isofile
linux  (loop)/isolinux/isolinux.bin
}

But during boot it shows 

error: file not found

What may be the problem here ?

TIA
