Original SP2 image is not compatible with newer setup engine. We need to use a trick - see engine folder in apps directory. Maybe it can work also with Windows 7 boot.wim with Windows 10 setup engine. But there are more ideas - we can integrate drivers using DISM into Vista PE. Also maybe fully updated image can be compatible - I started work on offline Vista updater, but this needs some time to see how it goes. These Vista things need more research.. EDIT: May be a good idea to rebuild Vista PE from scratch with latest updates, but I never tried it.
