[RESOLVED, by TSD]1950x will not boot media comp.

I just completed my latest build which follows:

Fatal1ty X399 Professional Gaming, Threadripper 1950X, 3xSamsung SSD 960 EVO, G.SKILL FlareX F4-2400CL16D-16GFXR, Windows 10 x64 Pro, Enermax Platimax 850, Enermax Liqtech TR4 CPU Cooler, Radeon RX580, BIOS 1.5

I tried adding this to my signature and far exceeded the 200 character limit.  The memory is a single borrowed stick from my R7.
The machine powered up and booted immediately to a message saying no OS found.  I plugged in a USB stick with WinPE.  It appears to boot displaying the windows logo but then just sits there.  I made sure Secure Boot was disabled and it was.  I tried a Windows install DVD and it does the same thing.  Everything looks normal in the BIOS.  I used Instant Flash to update to P1.50, microcode stayed at 800F11/800129.  I am starting my research and would appreciate anything anyone has to offer.

A RANT!  I am using borrowed memory because G.Skill says the TR BIOS (AGESA) will not support 3600 MHz.  I will open a ticket on ASRock and AMD on the down level AGESA (1.0.0.3 in BIOS P1.50).  I hope anyone interested in TR will do the same.
Thanks and enjoy, John.

Thanks, datonyb.  I have been doing my W10 (W7 before) installs for a long time by booting WinPE (built using ADK).  I then start a flat install (disk drive), so one of SSDs contains my install files.  The other two are new with nothing on them.  I saw the FlashBack feature, but did not want to be a pioneer.  G.Skill has some neat FlareX coming and they should (X399 TR only) be on the qualified list.  Thanks much and enjoy, John.

Two things come to mind..........

Only one SSD, connected to M2_1

Catch that this board has three power connections? 4-pin, 8-pin, and 24-pin?

Consider your wim used is now outdated? For TR I'd consider using the latest official 10 build released. Not one of the Preview ones.

Thanks, wardog.  I am nowhere close to the .wim file and I created it last week - a little down level but still W10.1703.15063.540.  I think your second comment may be the closest!  I tried enabling compatibility and could not even boot into BIOS.  I did a clear CMOS, then booted an old W7 install disk.  It went to the first install window with no problem.  Only trouble is my mouse and KB are wireless and W7 has no drivers.  If you will read my last post, I have removed everything except Monitor and power.  W10 install DVD won't boot but W7 does.  The W10 install disk boots just fine on this machine (R7).  I will quit for today but may move this optical drive to my TR machine tomorow.  Thanks and enjoy, John.
