Hi, jaclaz Short - yes, without internet connection setup cannot finish installation. I prepare Windows 10 with WinNTSetup v3.7.7 (with previous versions praparation finished with error. ( Sorry, I don't remember Nr. and text of error.)) preparation phase finished without error. After restart in final of installation Setup shows network adapters (LAN, Wireless) and here begin cyclingSystem restarts and begin from Language setup->Network setup and again restart. Until I start inetcpl.cpl from console and setup PPPoE and connect to internet. Now everything goes fine.
