most major Linux distributions offer a Live version, allowing users to run the OS without installing it
usually a CD or DVD, but it is possible to have Live USB Linux as well
users can boot the OS without affecting the existing OS, which can be very useful for:
hardware compatibility testing before install
trying out a new/unknown distribution
new or changed files can be saved on portable storage (such as a USB memory stick) or on the local hard drive
using Live Linux (Knoppix):
to run Live Linux (Knoppix) in a Virtual Machine using Oracle VirtualBox, you can choose Knoppix from your MyApps as soon as you log into Windows.
In case Knoppix does not show up in your MyApps after you login, you may look for C:\Knoppix\Knoppix.vbox and double click on the icon. NOTE: This may only work for computers located on campus.
to use Knoppix from your home machine, or on your laptop, you will need to download and install Oracle VirtualBox for your operating system first and then download the Knoppix VirtualBox VM (approx 5GB file and this might take a while to download):
Unzip the downloaded zip file (Right click and Select "Extract All")
Read and follow the instructions in the PLEASE-README-FIRST.txt file. It has instructions for running Knoppix on your home machine.
Should you still have difficulty running Knoppix on your home machine/laptop you may ask your instructor or the Learning Centre ULG leaders for additional help in troubleshooting why Knoppix was not working on your home machine/laptop.
