CD, a technology that soon will be history, here are 4 alternatives for using CDROMs:
1. Universal USB Installer – Has many linux installers with downloadable ISO.
2. Rufus – Source code is also available.
3. ISO2USB – A very simple and good tool to install Windows and any other ISO.
4. Windows USB/DVD Download Tool – Windows to usb ISO tool. Has a source code available but no so convenient tool.
