Weird -
Did you unpacked the .iso file before burning?
You need any DVD burner no matter which one. Recommended burning speed should be no more than 4x and that's all. There is not needed absolutely no chemistry to do. Also absolutely no needs for anything to change in the BIOS. Not matter, what order there is - usually it's already the right one. If your computer can not automatically find and boot from the DVD, open the Boot Menu and select it manually.
You can unpack an Iso file with WinRAR, for example, but almost any unzip or unrar program is suitable, which has an ISO extension enabled. Again, no chemistry is needed.
