grub.cfg Help

I am trying to make usb boot from iso images of parrot, kali and arch

I installed grub and put the iso to usb

and succesfully run parrot live directly from iso with this config:

menuentry "Parrot live" {

search --set -f "/Parrot-full-2.1amd64.iso"

loopback loop "/Parrot-full-2.1amd64.iso"

linux (loop)/live/vmlinuz findiso=/Parrot-full-2.1amd64.iso root=UUID=AB8E-115E boot=live hostname=parrot noconfig=sudo username=root quiet splash

initrd (loop)/live/initrd.img

}

Anyone know the grub.cfg configurations need to boot arch and kali 2016.1 ?
