Ondrej Sebela Hello Ondrej, thanks for fixing the USB script, it works. I have another issue. I followed the article, but when I try to boot from USB, the task Test-WebConnection google.com fails. Also the task Testing Wi-Fi Network Adapter fails. A window opens and I can see the WiFi adapter in the network settings. I guess this is no driver issue. I injected the latest Windows 10 and WinPE drivers from DELL. "Transcript started, output file is X:\windows\TEMP\wreconnect.log No Wi-Fi profile was found, making initial connection. (I deleted the WiFi profile for testing. Even with the profile, the sequence fails.) Start-WinREWiFi OK Test-WebConnection google.com FAIL Testing required WinRE content OK Starting WlanSvc Service OK Testing Wi-Fi Network Adapter FAIL Warning: Could not find an installed Wi-Fi Network Adapter Warning: Drivers may need to be added to WinPE" Any ideas what could cause this? I have the same WiFi adapter as described in your article. Thanks and regards, Mark
