I have an NT desktop I want to continue to use but do not want to be exposed to security issues after April 8. I've read I can boot the computer from a flashdrive with a Linux based OS installed on it and use the internet off the flashdrive while keeping the desktop safe. Will Ubuntu work for this? If so how big of a flashdrive will I need? Thanks.
In response to Danatela, yes I want to place a persistence file onto that USB.
