Tak jsem to úspěšně vyřešil programem ImgBurn, následujícím postupem:

1. After starting ImgBurn, choose in the overview "Create image file from files/folders
2. Insert Windows Vista DVD. On the "Advanced" tab -> "Bootable Disc" -> "Extract Boot Image" select the appropriate DVD drive and then click on the floppy icon.
3. Give the boot sector file a meaningful name; e.g. "Vista-BootImage.ima"
4. The next message window will ask whether this file shall be used for the current project
* this saves filling out the above fields manually
5. Thus, the fields under "Make Image Bootable" is automatically filled
6. On the "Options" tab, select "ISO9660 + UDF" and activate the checkbox for "Include Hidden Files" and "Include System Files"
7. On the "Labels" tab add the "Volume Label" for ISO9660 and UDF
8. On the "Advanced" tab -> "Restrictions" -> "ISO9660" activate the checkbox "Don't Add ';1' Version Number To Files"
9. On the "Advanced" tab -> "Restrictions" -> "UDF" nothing needs to be changed
10. Now insert the Windows 7 installation DVD and choose the DVD as source
11. Choose "Destination" ISO file name
12. For creating the ISO file click on the large button
13. After a short analysis the ISO file is created
14. After completion of the ISO file select the "Ez-Mode Picker"
15. As final step choose "Write image file to disc" in the overview window to burn the newly created ISO image file to disc
16. Select the just created ISO file as source
17. After inserting a blank DVD the burning process can now be started with the big button
