Sorry, I fell asleep last night. It was a long day.
The link is solid. You need to burn the ISO file onto the disc using special software. Simply copying the file onto the disc and trying to boot from it will not work, nor will mounting it with Daemon tools. You're on the right track, but the program needs to be booted from outside the operating system (you can't change partitions while they are being used- Windows would have a fit!

)
- Download Free Easy CD DVD Burner and follow the on-screen directions to install the software.
- Note: Free Easy CD DVD Burner is completely free and fully functional. However, there are some accompanying programs that it asks you to install - feel free to decline those if you're not interested. Free Easy CD DVD Burner supports Windows 7, Vista, XP, and 2000.
- Insert a blank CD or DVD in your drive.
- Open the Free Easy CD DVD Burner program.
- Click on the Copy CD/DVD button on the tool bar at the top of the program window.
- Under the Action menu on the left, click the Burn an Image file link.
- When the 'select the image file that you want to burn window' opens, locate and select the ISO file you wish to burn to the empty disc and then click Open.
- A dialog box will appear asking "Do you want to burn [your chosen ISO file]?".
- Click OK to confirm.
- The burning process will automatically begin. The time it takes to burn will depend on the size of the ISO file and the speed of both your PC and your CD or DVD burner.
- When the burning is complete, the CD or DVD will automatically eject from the drive. You can remove the disc and close Free Easy CD DVD Burner.
- If you view the contents of the disc, you might notice many files and folders. So what happened to the ISO file? Remember that the ISO file is just an image of what should be on the CD or DVD. That ISO file contained the information for all of the files you see on the disc.
Credit to Tim Fisher for these instructions.After that, just insert the burned CD into the CD-ROM, reboot the computer, and change the BIOS boot order so that the system boots from the CD first, instead of the hard drive. Follow the prompts and wait for GParted to load, then work you magic.

And remember-
back up your data before altering the partitions!
Hope that helps! Let me know if there's anything else I can do to assist you.
