“Linux Live USB Creator, a similar program, can help create live
USB drives, but it only works on Windows. Live USB Install works on
both Windows and Linux, and is incredibly simple to use. Just pick
which version of Linux you want to use and which drive you’d like
to install it to. Your software will be downloaded and installed,
and you will soon be able to live a contented life involving the
booting of Linux from a USB disk.
If this sounds complicated, don’t worry: it isn’t. Your disk
will be up and running in no time.
