How to use YUMI to create a USB with persistence?

Question

I've made a multiboot USB using YUMI. I chose Ubuntu and Kali Linux.
The USB loads great with Kali and with Ubuntu, but Ubuntu always only gives me option to "try" and "install" and nothing as save when restarted in "try" mode.

I've heard about adding "persistence" somewhere but I'm such a beginner that I can't fully understand what to do.

I use Windows to create the multiboot.

YUMI Persistence

Persistence for Ubuntu installs in YUMI is step 4 of the installation procedure as shown below.

BIOS/UEFI mode YUMI persistence is limited to 4GB.

BIOS only mode YUMI persistence is unlimited.

Hi! Here are some explanations and, also, some alternatives to YUMI: linuxliveusb.com/en/help/faq/persistence/67-what-is-persiste‌​nce "Usually, on a live CD or Live USB key, all modifications are discarded when you reboot." - LiLiUSB Creator The persistence allows you to keep your preferences and data even after reboot. The data are stored in a special file called casper-rw (for Ubuntu) and overlay-USBLABEL-UUID (for Fedora). This is a completely transparent process for the user. Usually, 300 MB are enough to install some software but you can use more."

i tried using liliUSB but i dont believe it lets you have multiple os

YUMI works great for me, formatting the drive NTFS allows greater than 4GB persistence. remember to adjust persistence size before adding an OS.

@90albu No, liliUSB doesn't allow multiboot, for multiboot on Windows, there are several softwares.
