Instructions
Insert the CD into your computer.
Open "My Computer," and right click the CD drive, then click "Open". This will bring up the Windows CD burning window.
Click "Erase this CD-RW" in the CD Writing Tasks pane. This will bring up a wizard; click "Next" to erase the drive.
Open the Windows CD burning window again as explained in step 2. Drag all the files you want to burn to disc to this window, which acts as a staging area for files to be burned to disc. Click "Burn Files to Disc" when you're ready.
