"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
A problem caused .... please close the program.

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.

Thank you very much for the instant reply! Yes, I re-read those steps, and discovered that I am very familiar with them: just yesterday I made a repair disc for another W 7 laptop (so that I could use a system image to swap hard drives).

Unfortunately, in this laptop, under "Control Panel\All Control Panel Items\Backup and Restore"
- the "Create a System Repair Disc" subwindow opens,
- but immediately on top of it, the failure window appears and covers the subwindow (one an see over the edges of the failure window, that the drive selection subwindow text is still greyed out). Of course, the dominant window is the failure window, I can't get back to the "Create a System Repair Disc" subwindow.
= I can't select any drive, DVD or USB, to use as a repair disc

(I did the DVD drive test just because it was recommended in forums, not because I thought it had relevance.)

I may have overlooked completely something simple (as in my July post). But this seems to be a major W 7 applet failing as it should not.
