ok - do you have to have to manually put it on a USB first? and can you then run it on any laptop without having to change the OS of that laptop first? is that right?
Download the image, follow the instructions to confirm the image is not tampered with, "burn" thr image to a USB, load off the USB and you're good to go. It doesn't touch the hard drive at all.
Let me know if you need help with it.
