It is also possible to install a bootable image onto a flash drive manually, and there are several good step-by-step guides to help you through this process. If you are simply interested in building a portable environment like the one you use at home, you should start by looking for such a utility within your distro.īranching out a little, there are a handful of good multi-distribution live USB creation utilities you should consider if, for some reason, your distribution of choice does not provide the options you need. With the rise in popularity of optical-drive-less netbooks and tablets, providing USB as an installation path guarantees that the distributions will continue to make booting from flash a priority. Most of the popular desktop distributions provide live CD images for testing or installation purposes, and include a utility to install such an image onto other media, including external hard disk storage or a flash drive. The first question you need to answer for yourself is what distribution you wish to use as the basis for your live USB key. A variety of tools can help you tailor a live USB distro to your liking, including data persistence and encryption, so grab an unused USB flash drive from the desk drawer and make exactly what you need this weekend. Thus, when you’re vacationing or on a business trip and need access to a Linux environment - or get the inevitable PC troubleshooting help request - you’ll have to have a bootable distribution with you. Until world domination is complete, you simply cannot count on Linux being available everywhere you travel.
