We can use Universal USB installer to create Live USB images from Live CDs. For example we can create bootable USB disk for system rescue CD with universal USB installer.

Note:


One can also use Linux live USB creator to create live USB images from ISO images of CDs. Linux live USB creator will even allow installation of virtual box so that live USB can be used directly in Windows without persistent storage

Other option is to use Rufus available at https://rufus.ie/


To do this using CentOS 7.x instead of Windows refer CentOS 7.x Fedora Live USB creator
