1st recipe

• Extract Linux CD in USB root
• Delete folder [ROOT]
• Copy the files to USB root:

 menu.c32
 syslinux.cfg
 ubnfilel.txt 		(list of all files on the cd - probably useless)
 ubnpathl.txt		(list of all dir on the cd - probably useless)

• Copy /casper/vmlinuz to /ubnkern
• Copy /casper/initrd.lz to /ubninit

• Use "PDL-Casper-RW-Creator.exe" to create the casper file
• Then edit D:\syslinux.cfg (where D: is the drive letter of your usb stick), and add "persistent" at the end of the line that begins with "append":

default unetbootin
label unetbootin
  kernel /ubnkern
  append initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash persistent --

Another way to create the persistent file

To create a persistent file (4GB file):

dd if=/dev/zero of=G:\\casper-rw bs=1M count=4090 --progress
mke2fs -b 4090 -L casper-rw G:\\casper-rw

To create a persistent partition:

sudo mkfs.ext3 -b 4096 -L casper-rw /dev/sda1
dd if=/dev/zero of=/media/hda1/casper-rw bs=1M count=128
mkfs.ext3 /media/hda1/casper-rw

Yet another way

• Created partition: 1 for extract iso, 1 for casper-rw
• extract the .ISO to usb
• make the drive bootable:

syslinux -maf X:

• delete [BOOT]
• created /syslinux.cfg
• include /isolinux/isolinux.cfg
