The first barrier to remove is the need to find and download a Ubuntu ISO image. The aim should be to allow the creation of a startup USB without the need to leave the program (to download an ISO), with the lowest amount of user interaction (clicks), in the most polished way. It should be really easy to create a startup USB stick, therefore the SDC should automate as many tasks as possible and hide all non-essential or technical information from the user. The SDC is kind of a semi-public face of Ubuntu and an important tool to spread it, therefore it should be as straightforward and simple to use as possible – some people even don't have an optical drive anymore. The SDC in its current form has a suboptimal work flow, displays too much unimportant information to the user and requires too many steps to actually create a startup USB stick. Why the Startup Disk Creator (SDC) schould be redesigned
