Ubuntu – Create a LiveUSB from existing Ubuntu / Xubuntu installation

live-usbvirtualboxxubuntu

I have a Xubuntu in my VirtualBox machine with several changes, and I'd like to make a LiveUSB out of it.

I've already heard about Remastersys, but it's not supported anymore. How to customize the Ubuntu Live CD? explains how to customize a LiveCD but it needs an ISO as a base, I can't use an existing installation.

Relinux also seems to be abandoned.

How can I create a Live USB from my Xubuntu installation?

I think you what you need is Clonezilla which can backup the whole disk or only the selected partition (cant say it is a "Live CD/USB"). There are many tutorial available in the internet like this one. There is also Clonezilla live that allows you to use CD/DVD or USB flash drive to boot and run clonezilla.

As alternatives you can try Systemback which will help you create live system (currently only works for Ubuntu derivatives based on 14.04, 14.10, and 15.04). To install this, run:

sudo add-apt-repository -y ppa:nemh/systemback
sudo apt-get update
sudo apt-get install systemback

There is an excellent tutorial on how to use Systemback.

There is also a tool called Mondo Rescue which you can try.
