Instructions
Insert a blank disc into your CD/DVD-ROM drive.
Locate the Wii ISO you wish to burn. Use Windows 7's built-in search engine by clicking the "Start" menu and typing the ISO image's name in the Search field. Alternatively, go to "Start" and launch the "Computer" applet to manually locate it within your local hard disk.
Double-click the Wii ISO image to launch the "Windows Disc Image Burner" application. If your ISO images are set to launch with other programs, right-click the file in question, select "Open With" and launch "Windows Disc Image Burner" from the context menu shown.
Enable "Verify Disc After Burning" to have Windows 7 inspect it for potential errors. Otherwise, click "Burn" to initialize the ISO copying procedure.
