Linux live CDs have been a game-changer in the history of open-source operating systems. From the early days of Yggdrasil and Knoppix to modern distributions like Xubuntu and Manjaro, these live CDs provided users with a convenient way to explore Linux without committing to a full installation.

The ability to boot a fully functional Linux environment directly from a CD not only made Linux more accessible to a wider audience but also served as a valuable tool for system recovery and troubleshooting.

FAQ: Linux Live CDs

A Linux Live CD is a bootable CD-ROM or USB drive containing a complete, self-contained operating system that can run directly from the disc without installation. It allows users to experience Linux without modifying their existing system.

Live CDs are used for: testing Linux distributions, recovering data from broken systems, troubleshooting hardware issues, and running secure, temporary operating environments without modifying disk partitions.

Insert the Live CD/USB, restart your computer, and access the boot menu (usually by pressing F12, ESC, or DEL during startup). Select the external media as the boot device.

While USB drives have largely replaced CDs, Live USB sticks remain important for system recovery and demo purposes. Many distributions now offer hybrid ISOs that work on both CDs and USBs.
