Hello ! I'm new in this forum, and I've read all of this thread, I've tried to install the last driverpack base with the fix and all the driverpacks, and it doesn't work ... It was working perfectly with the last versions but with this one i have problems with winnt.sif : -- Into the OemPnpDriverpath I have lots of blank lines, lots of "D/blablah;"D/blablah ... -- When I remove this, even if I totally remove the OemPnpDriverpath, I can't launch Windows's installation ... it keeps telling me "there is an error in your winnt.sif at line XX", and it is always the last line, even if I remove everything ... I use method 1, with GuiAttended Thanks ...
