Well some progress - VMWare Fusion now reliably sees Creators Update Boot Camp partition and adds it without the "boot.ini" file. However whilst it now recognises a OS, it sees it as Win 8 x64 instead of Win 10 x64. More seriously though it doesn't boot, it goes straight to Recovery menu. The boot config for the PC is missing or contains errors. Needs to work reliably with machines restore from WinClone as well.
