Yes, I think that's the problem I have.
There is no persistence on my USB. Also, the gnome shell fails to load.
The Yumi software has debian installer removed. I read on debian.org that all the third-parties slim-down the debian live OS which includes removing the debian installer.
Debian does offer installation of live debian OS onto a USB, but you have to already be in a linux environment.
Pendrivelinux and unetbootin, both with versions for windows, will create a bootable flash drive which should have the installer. I'm not sure why you are using YUMI since it is designed for multiple systems and you are only putting one system (Debian) on it. If you read further at the link above, this is explained.
Ok, I'm going to go back to Windows and use a different program to Yumi to install a fresh live debian OS onto my USB.
Hopefully, this will have debian installer else they're short-changing people by not offering the proper debian live OS.
I'm also going to see if I can find versions which have persistence built-in.
Thanks Yancek, you've sorted out my problem.
