Wyse5070 - assistance with findind O/S to create bootable USB

Hi

have a Wyse 5070 which had a blue screen of death - o/s corrupt and need to reinstall.  I can see how to create a USB boot file and got o/s installed, but have now been told it was the wrong o/s and I need Windows 10 Enterprise 2016 LTSB 64 bit.

Cannot find the correct file to download from the support pages - and finding the Dell support pages are a nightmare to navigate! probably just me being a newbie...

Would appreciate if someone can tell me where to download the files from so I can then use the imaging tool to create the USB Boot.

thanks in advance.
