JFX, Thank you very much for your reply. The "sysletter:c" did the trick!! I'm very happy that everything works now, this means that I come ever closer to my "everything on one USB stick" goal! Right now, I have Win PE SE on it, some more Grub-started stuff (Ghost, ADDS, etc), W7 setup from WinPE SE (thanks to WinNTSetup2!), my backups (Truecrypt volumes), etc. As I said, the Windows 7 setup is going smoothly, including autounattend.xml. I'm using the same file as I used on my "standalone" W7 install stick (that install is completely unattended, except for the HD partitioning screen). When I use the file in *this* setup (using WinNTSetup2), there is one (and only one) screen I get, just before setup is done. It's the "Activate" screen, which asks me for the serial. The screen also has the "Acticate automatically" checkbox. I didn't get this screen on the "other" USB, so I wonder what particular setting it is that I should add in autounattend.xml. But I'm VERY happy with the way things are going up to now, thank you very much for this great utility!!!
