I wrote a linux shell script to write an iso with persistence to a USB drive.
You could boot kali USB without persistence, run the script on another USB drive.
Please let me know if it works for you.
Code:
#!/bin/bash
# vi:nowrap
# write iso with persistence
# kali-persistence.sh {iso}
# *** IMPORTANT *** edit DEVICE as needed ***
DEVICE=/dev/sdb
# .......1.........2.........3.........4.........5.........6....
if [ ! -e $DEVICE ] # device exists ?
then
echo;echo "device $DEVICE ?";echo;exit 10
fi
ISO=${1}
if [ ! -e "$ISO" ] # iso exists ?
then
echo;echo ".iso $ISO ?";echo;exit 10
fi
# .......1.........2.........3.........4.........5.........6....
# writing the iso creates 2 partitions
echo;echo "Write $ISO to $DEVICE"
sudo dd bs=1M if=$ISO of=$DEVICE oflag=direct status=progress && sync
PERSIS=3 # write persistence to partition 3
START=$(du -B1000000 $ISO | cut -f1)
END=$(lsblk --noheadings --nodeps --bytes --output SIZE $DEVICE)
END=$(($END / 1000000))
echo;echo "Persistence on $DEVICE$PERSIS from $START to $END"
sudo parted $DEVICE mkpart primary $START $END &&
sleep 1
sudo mkfs.ext3 -L persistence $DEVICE$PERSIS &&
sudo mkdir -p /mnt/kaliUSB &&
sudo mount $DEVICE$PERSIS /mnt/kaliUSB &&
sudo sh -c "echo '/ union' > /mnt/kaliUSB/persistence.conf" &&
sudo umount $DEVICE$PERSIS &&
sudo rm -fr /mnt/kaliUSB/
sudo fdisk -l $DEVICE
# .......1.........2.........3.........4.........5.........6....
