The main option for creating a "live disk" is the recording on a CD/DVD, which allows you to use the standard tools of the original operating system. Additional, though in fact, already the main one, is the write to USB-Flash, which can be carried out from the environment of the Linux operating system, for example, from the environment of the same "live disk", recorded and downloaded earlier from a CD/DVD; or from the MS Windows operating system via Win32DiskImager.
