1. You don't run it under windows, unless in a Virtual Machine, which we won't do for the moment
2. Google search "Burn ISO to disc", and follow it's instructions
3. Either set your motherboard to boot from CD, or if that's already done, put the cd in the tray and restart your computer. If you don't know how to do this, use Google.
4. Enjoy backtrack, but do one heck of a lot of reading, and I would start off with something simpler like Slax or Ubuntu, just to get the hang of linux, rather than starting with an advanced, professional Distro.
SO you re-downloaded the iso and it's now working in Windows from the C:/ prompt??

I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
