So can somebody help me how do I install Tiger on this 8gb what do I do with this tiger-x86.tar.bz2 I can't burn it like iso. Pls help i know it annoying to explain something to someone who doesn't have a clue but i need this step by step... I have seen some tutorials but i don't have clue how to begin? Do i extract this tiger-x86.tar.bz2 and than burn it on DVD and boot from it and install like windows?
