"Create A System Repair Disc" Fails

Microsoft Windows Repair Disc refuses to work. What should I do to allow creation of a System Repair Disc?I created (I think successfully, as the Finish window seemed normal) a System Image on a USB hard drive. The image was created overnight.After the image was created, while still inside Backup and Restore, I received the sub-window, asking if I wanted to Create a System Repair Disc. I inserted a new DVD, and clicked to start the process.The "Create a System Repair Disc" subwindow opened, to allow the drive selection.Immediately thereafter, (with the drive selection window text greyed out) before the I could even see the drive selection drop-down arrow, a failure window opened on top of it:Microsoft Windows Repair Disc has stopped working?If the debug option was chosen, the same window appeared, but without the Debug option, leaving only the Close the program option.I rebooted, and via Backup and Restore, again tried to Create a System Repair Disc. This failed the same way. I rebooted, and used another freshly unpacked DVD. The same failure occurred.Following forum post suggestions, I have subsequently successfully burned and verified a DVD on the DVD drive.I use Windows 7 Professional on an Asus U50-F.Yesterday -- maybe a coincidence -- before this failure I also installed (successfully) all of the most recent Windows Updates.
