I've got a "live" LM 18.3X. Added a "casper-rw" partition. Now, I need to get the O.S. to recognize/use that partition.

What file do I go to to change the command lines and what are those changes I must make? I looked at a site that gave instructions for Ubuntu, but haven't found one for Linux?


Linux Mint iso files are similar enough to Ubuntu iso files for mkusb to create a persistent live drive with a casper-rw partition and prepare 'everything' on the drive for it to work. See the following links,




sudo add-apt-repository ppa:mkusb/ppa  # and press Enter
sudo apt-get update
sudo apt-get install mkusb mkusb-nox usb-pack-efi

This screenshot illustrates a persistent live system, where aufs matches casper-rw, here at /dev/sdb5:

Edit: The following screenshot illustrates mkusb running in Linux Mint (persistent live created from linuxmint-18.3-cinnamon-64bit.iso).

  • I got E: unable to locate package mkusb. Subsequently, all the other commands returned the same E; – Rick Jul 19 '18 at 2:29
  • @Rick, Which linux distro and version did you run, when you got 'E: unable to locate package mkusb'? It works for me to install mkusb in Linux Mint via the PPA as described in the answer. See the edited answer with a second screenshot. – sudodus Jul 19 '18 at 7:38
