Kali USB – Multiple Persistent Stores

[prompt_32]

i try to build this usb configuration, as described in the following link :

https://www.offensive-security.com/kali-linux/usb-multiple-persistent-stores/

i follow the steps described, using the 64bit iso from here :

http://images.kali.org/kali-linux-2.0-amd64.torrent

I think everything is ok, and after i finished, considered my usb device as /dev/sdh,
i have the following :

##
## parted -l <device>

Model: Kingston DataTraveler 2.0 (scsi)
Disk /dev/sdh: 7757MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

3 3321MB 5000MB 1679MB primary
4 5000MB 7757MB 2758MB primary ext3



##
## fdisk -l <device>

Disk /dev/sdh: 7757 MB, 7757398016 bytes

##
## blkid |grep <device>

/dev/sdh1: LABEL="Kali Live" TYPE="iso9660"
/dev/sdh2: SEC_TYPE="msdos" UUID="C655-7B4F" TYPE="vfat"
/dev/sdh3: UUID="aee9de21-fa81-43f5-9ff6-2e634bedf30a" TYPE="crypto_LUKS"
/dev/sdh4: LABEL="uspace" UUID="718d91fa-3e1e-4633-8490-bdba2e56c037" TYPE="ext3"



My PC is a x86/32bit machine, so to test this usb config, i make this script :

#!/bin/sh


# this usb UUID
thisUsbDev=`blkid|grep "Kali\ Live"|cut -c1-8`

# RAM in megabytes
defaultMemory=512


# uncomment, to make changes to temporary files, not to any drive
#OPS='-snapshot'


qemu-system-x86_64 ${OPS} -cpu qemu64 -net nic -net user -m ${defaultMemory} -cdrom ${thisUsbDev} -boot d

, and it runs very very nice !

My problem is,
that when i give my usb to someone with a real x64 arch, it fails to boot ...


Is something i do wrong, or my PC's arch, dont create, what its supposed to ?
