Gets to the actual installation, reboots and does an "Undoing"
without a reason.
I guess totally (it's how I got TPM to run and "attest")
But I'm running out of ideas.
My next idea is to slow down memory (from rated 3600 to maybe 3000) but now I'm just grasping straws.
Slowing down memory did not help; It installs 100, restarts, flashes a message about continuing and how it might restart, for maybe 1/4-second,
reboots and shows "Undoing" and I'm back to windows 10 21390
This is hopeless.
Disable "secure boot"? I'm totally guessing again.
