Hi all - UPDATE:
I had some success last week. I managed to work out how to use WinImage Version 10.00 to make image files out of files on my desktop and successfully import them into a working environment and be able to be read. I also discovered ImgBurn is a great piece of software for making an ISO of a group of files and they seem to work fine in EaaS in my emulated environments. So it is progress.
In another issue entirely though I keep running into the issue that a few pieces of software want to run in a higher resolution and colour gamut than the VGA 16-colours that is set on the various stacks I have in my instance of EaaS running QEMU 2.11. I tried later versions of QEMU but 2.11 so far seems to be the most stable for creating windows-based PC environments. A minor annoyance, but otherwise, am pleased with the help I have received so far.
thanks,
Tim
