Hello there,
The CD writer wizard is not available in Backup Exec version 10.0 as the latest version supports only third party software for burning the ISO image.
Write the image to CD following directions for the software you are using to write to CD-R / CR-RW.
When browsing for the file, be sure "*.ipso" or "all files" is selected under "File type" (or equivalent) and navigate to the ISO image.
We hope this helps you.
Thank you
