Instant Linux for Windows admins means no installation
Many Windows administrators want to try out Linux without having to install an entirely new operating system alongside XP, or reformatting their hard disk.
Now there's a way to get "instant Linux" – with the free software called Knoppix. It runs straight from a CD, so you don't need to do any installation at all. Just boot your computer from your CD, and what you get is instant Linux.
The simplest way to get started with Knoppix is to download a CD image, burn it to a CD, then boot from the CD.
