Part 1. What Is Knoppix?

KNOPPIX can be modified as a Linux demonstration, training and rescue system, or tool for advertising enterprise software demos. A hard disk installation is not required. Transparent decompression allows up to 2 gigabytes of executable software to be installed on a single CD of the Knoppix CD and up to 10GB on a single-layer DVD.

Hardware Requirements

Running Knoppix to access data from an unbootable computer requires the following:

  • Intel/AMD processor compatibility (i486 or later)
  • RAM requirements are as follows:
  • Text mode requires 32 MB.
  • No-swap live environment:
  • 512MB for graphics mode when using only LXDE
  • 1GB for web browsing and productivity software
  • 2GB is recommended.
  • An optical drive that can be booted.
  • For current versions, use a DVD-ROM.
  • For versions 7.2 and earlier, a CD-ROM or a boot floppy and standard CD-ROM (IDE/ATAPI or SCSI).
  • Graphics card with SVGA compatibility
  • A standard serial or PS/2 mouse or an IMPS/2-compatible USB cursor.


Knoppix is a Linux distribution that can be run directly from a CD or USB without installing it on your hard drive. Some its major attributes include:

  • Automatic hardware detection: Knoppix can automatically detect and configure most hardware devices, including printers, scanners, and webcams.
  • Live boot: Knoppix can be run directly from the CD or USB without affecting the existing operating system or files on the hard drive.
  • File recovery and system repair: Knoppix includes various tools for recovering lost files and repairing system problems.
  • Graphical user interface: Knoppix includes a graphical user interface (GUI) based on the KDE desktop environment, making it easy for both beginners and experienced users.
  • Multilingual support: Knoppix supports multiple languages, including English, German, Spanish, French, and many more.

The Latest Version

The new "public release" on January 2021 serves as the basis for the issue version Knoppix 9.2 on the latest technological page. It is now possible to create a slimmed-down CD version - a little retro, but a minimal practical basis for customized remastering projects without backfill - through a slightly complex redistribution of the software packages within the compact cloop-compressed images. Many Knoppix mirrors now have the CD version available in a different directory.

Part 2. How To Perform Data Recovery With Knoppix

This section will show you how to recover files from a crashed Linux computer using Knoppix. The recovery process is performed with the Knoppix live Linux CD, and you can follow along even if you've never used Linux before. If these steps trouble you, here is a video tutorial for a more comprehensive explanation.

Note: In this example, Knoppix 6.0.1 will be used. Your Knoppix may look different as newer versions are released, but the general file recovery steps will remain the same.

Step 1. Download an ISO image of the most recent Knoppix operating system from one of the Knoppix mirrors listed below. Choose the server based on its proximity to you. Choose the most recent version and save the.iso file to your working computer.

Step 2. The hard drive is most likely listed as the first device in the boot menu on your device. If this is the case, the laptop will not automatically boot from the Knoppix CD. Boot it from the CD/DVD drive.

Place the Knoppix CD in the optical drive and restart the computer. When the logo appears on the screen, access the boot menu by pressing F12. Enter and select the CD/DVD drive as a bootable device.

You can also enter the BIOS setup menu and change the boot order. Check that the CD/DVD drive is listed before the hard drive.
