Windows 10: Win 7 to Win 10 upgrade continues to fail and many weeks of trying

After all suggested fixes and workarounds antivirus, USB peripherals, clean boot, disk space, ScanHealth/RestoreHealth, removing bad manifests, all of that, over and over, I get the same error message: 0x800704B8-0x3001A The installation failed in the FIRST_BOOT phase with an error during BEGIN_FIRST_BOOT operation.


My biggest challenge, perhaps, is that I don't know how to interpret the log files. And apparently, neither do the Microsoft tools I've used that are supposed to do just that. So in the hope that a nice Microsoft expert has time on his or her hands, sees my post, and wants to take a peek at my log, I've provide it here: https://1drv.ms/u/s!AjUc6e8QX2MOgS7jqFLtsNZ6hKcq


I'm on Windows 7 Pro OS, on a machine that I built myself in 2016 with all new components and an AMD64 processor. Each of my older, smaller, slower machines at home are already on Windows 10, so there's no doubt that my system can handle the upgrade. If I cannot find a solution on this forum, I will have to go through the arduous task of installing as a new system and then reinstalling all of my many dozens of applications. I hope to not have to do that, as I bought Windows 10 directly from Microsoft and would expect that the thumbdrive they sent me would simply do the upgrade I paid for. Call me naive.


Thanks, anyone.

is hardware OK (Win 7) for upgrade to windows 10

I think in one of the other PC with win 7 or win 8.1 I run media creators tools and in some step prompt/found graphics card not supported... for win 10. I didn't found alone reading specs of win 10, but the tool says me... after changed graphics card the tool said all OK and continued OK with upgrade... That I ask to reach this step in this current PC - win 7 - must be all OK for the upgrade? Or must continue to upgrade to show this?
and got to point

• UPGRADE this PC now
• Create media(DVD, USB stick, ISO)

is hardware OK (Win 7) for an upgrade to windows 10 for this PC???
