Sorry for not replying earlier I saw the post but it was in the middle of removing sata cables to be sure all files remain on the disk I installed the OS to ( a problem I've experienced with dual boot before). At the same time, my Samsung CFG73 was presenting itself as the culpret of the situation where a display signal is not always picked up (not a problem ordinarily since it finds it on hittng the desktop). I reset the bios but that only served to illustrate the signal is a problem for the Integrated IGFX and my vega 56 is not the cuplret. Sorry for the tangent.
TO THOSE WHO UPGRADED TO WIN 10

The above explaination was illuminating because ofcourse I have the option in NTLite to disable this stuff beforehand. I also went to blackviper for service tuning. However part of the problem was that I must have been too eager to hack the ISO filesize down, make other changes; because the setup failed after I got a monitor signal back (didn't matter if I was using display port or not, flakey monitor signal is flakey. The monitor in other respects is grand however. I didn't need to grab another older monitor, it eventually resolved it own problem on its own.
After reading posts about trying to execute scripts and minor hiccups such as detailed here:

I've decided that I can run the script on the windows 10 desktop to save time and effort.
FYI I've got the mining bug and some programs like xmr-cast don't support windows 7 and I could not get the amd blockchain driver to hit the desktop in win 7 (reboots just as the desktop is appearing). I'm glad I have setup multiboot to test this stuff. Keeping my main boot OS on win 7 sp1.
