Windows 10: Not able to see anything on safe mode screen

I'm having nothing but problems trying to rebuild my DAW -- I'm getting extremely depressed and I don't like windows 10 at all. I briefly got the OS to run after replacing the Mobo, chip, and memory then added in two 2TB M.2 (samsung). I had installed the old 'c' drive (sandisk 1tb ssd) and my primary data hdd which came along with the recycled system that I used for the build. I was happy at that point, looking forward to the start of customizing the rig the next day. I just left it on and idling overnight to let dropbox do some housecleaning and catchup. Next day the problems started. First, the OS was no longer activated and I spent 7 hours going round and round to find a way to recover the digital license that was provided when I did the free update from Win7ultimate to Win10Pro. I won't belabor the details but suffice to say I was forced to buy a new product key because no one can find or tell me where to get said digital license. Once that was installed, the system wanted to do updates and after that I attempted to migrate the OS from the old sandisk to one of the two new M.2 drives. After that seemed to be successful and I rebooted several times, I was going to move on to my next task when the system suddenly froze and rebooting ended up with a single log-on (my account but there were four others defined) and when I rebooted I got the dreaded, "The user profile service failed the sign-in. User profile cannot be loaded." I tried some of the OS built-in repair options and even tried a restore point from before the changes. The only thing I noted is that the restore point did not appear to be able to see the data drive which was attached and seemed to be working. Next, I researched that problem but the only way I can do anything is by getting into safe mode -- preferably with networking so I can look stuff up. I can do the steps required to get to the F4/F5 safe mode start but all that happens is that my screen goes black with a cursor and hour-glass and just sits there and flickers endlessly (well, I let it go for over an hour with nothing happening). I don't know what other options there may be or what is causing the problem. I can neither use my old boot drive nor can I seem to use my M.2 install. I can't get to a registry to try finding the problem, I can't sign-in and I can't do safe mode so far as I can tell. I'm thinking the only things left to try are to (preferably) 1) do a repair install or (far less preferably) 2) do a reinstall of Windows 10 Pro. Problem is, I don't know how to do this when I did the free update (back last March) or where I would get the right disk to do the right install without having to buy a copy. Anyone have ideas on how to get out of the morass I find myself in?
