My script has been running now for half an hour; still "copying windows"...and files on the USB stick with a total size of 456 MB...
Will wait some longer...(the "cleaning up the installation image" at the end takes some time)
Update: wrong Enterprise image; no error message. Problem solved with other Enterprise ISO version.
Went a lot faster.
Some tips:
* Formatting a >32 GB USB drive to fat32 with this GUI tool: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm
* Mount an Enterprise Eng ISO version in windows explorer
* Download the files mentioned on Technet to a folder "123"
* Search for CMD in windows and start it as an admin
* I have used this sctipt at the command dos prompt:
powershell.exe -ExecutionPolicy Bypass -File c:\123\createsrsmedia.ps1
* Script starts running and asks for some questions (told i was enterprise user)
