I downloaded the Windows 10 version 1909 ISO and created USB installation media on MacOS using UNetbootin.
On the Windows target machine, the installation program started properly. It asked about my location, keyboard and so on. But upon beginning the actual installation, it gave the error:
Windows cannot open the required file D:\Sources\Install.wim.
Make sure all files required for installation are available and restart the installation. Error Code: 0x800700D
Contrary to what the message says, the file exists. What is the problem?
