Hello everyone! Sorry for posting here, but I don't want to start a new thread.
Slipstreamig updates to Windows 7 failed for me too, but in another way.
In my case no warning appeared during or after integration, and then I tried the created ISO in VMWare.
Setup booted successfully, but after the first reboot, the system won't start, stops on boot screen without any error.
No NVMe patch was installed, only those which had been listed by NTLite.
Don't know if I'm missing any update or included something that causes Win7 to stops booting and stays on boot screen.
Update: forgot to mention, installation using the source ISO (found
here) booted on the same VMWare configuration (SATA HDD, guest OS set to Windows 7 x64).
