When you use a CD/DVD to boot and erase a disk, you will be asked to enter an Answer Key.
IMPORTANT: Do not restart the computer when DisposeSecure is asking for an Answer key. This is because each time you boot your computer a new "Protection Key" is generated and each "Answer Key" is unique for each unique Protection Key.
For getting an Answer Key: leave the computer on the Answer Key prompt and write down the link and the Protection Key that appear on the screen.
Please use an alternative computer or a mobile Internet device to visit the link that appears in the DOS screen and enter the Protection Key on the web page. You will receive an Answer key immediately.
Enter the Answer Key on the computer that you booted using the bootable CD/DVD. You can now continue the sanitization process.
