I use Nero to burn my CDs and DVDs. There are also other programs out there that you can use to burn the .ISO file with.
Well after you download the Distribution(Distro) of your choice, you'll notice the extension is .iso
NOTE: You do NOT un-pack that .iso file even though it'll look like you can with some zip and rar archiving programs.

In Nero you want to select to burn an Image to Disc.

Then the following window will come up.

Select the .iso file. In this example I selected Gobo.
NOTE: Make sure that at the bottom of the window you have it set to show all file types.
After the burn is done, the disc will be ready to use. Just leave it in the drive and reboot and make sure that in the boot order in the BIOS that the CD-rom drive is set first.
Make sure you already have free space set away on the hard drive for Linux before you reboot.
