remove or add 1) without having to start from scratch? What is the range of Ubuntu versions it supports?.Some advice/guides/tips on how to go about getting the best out of the chosen program?.This is the primary question for the thread while I have a few more below for anyone feeling like providing some additional guidance. So, coming back to the former 2 options, which would be the best choice for the functionality needs I have explained above? Is there a better alternative you know of? In case it's relevant, ideally, I'd like the program to run on Linux but I do have a Windows 10 device, if required. Note, I've purposely left out YUMI due to the disclaimer stating ' Installing Linux from the YUMI created USB Drive to a Hard Drive is not officially supported' & SARDU due to lack of any updates during the last few years.

Some programmes I've come across that could help me are MultiBootUSB & Easy2Boot.

Understandably, this is a rather tedious process & one I'd like to make more efficient. This allows me the flexibility of installing 14.04 on a device or copy over the ISOs on to the host device then select one of them to use as my chosen bootable flash drive OS. I got a new 32G USB flash drive recently &, naturally, I converted it to a Ubuntu 14.04 LTS bootable flash drive while storing some other version ISOs, including: 10.04, 12.04, 14.04 & 15.10, in a separate folder (required for testing occasional backwards compatibility where I have enough spare old machines to use them instead of running VMs on my slow machine).
