In order to make the new CD bootable it's necessary to add the file Microsoft Corporation.img to the folder SS-Boot we created earlier. There are a number of ways to do this but the easiest is to use ISO Buster With the Windows XP CD in your CD drive, open ISO Buster. Click on Bootable CD in the left pane then right click Microsoft Computing.img in the right pane, finally clicking Extract Microsoft Corporation.img file.
