Can't boot into Windows 10 EFI

If I did something wrong I can re-do it.

Maybe NavyLCDR has ideas on a fix or redo.

What we have is great big huge mess. What I would do is wipe the new SSD completely clean. Do a new, clean install of Windows 10 to it. See if the works normally. Then clone only the partition containing the old Windows 10 to the new drive right over the top of the newly installed Windows 10. Only clone the one single partition and only replace one single partition, we are not cloning the entire disk. See if that works.

HOWEVER, the black screen with the spinning dots indicates that you have gotten past the BCD stage and all this fussing around with the BCD was never likely to fix anything. You might just have to settle with a new clean install on the new SSD. The black screen with spinning dots is normally caused by a malfunctioning driver in Windows for disk controller.

I tried to fix it with:
SFC /SCANNOW /OFFBOOTDIR=D:\ /OFFWINDIR=C:\Windows
It didn't work.
I tried to fix it with:
DISM /Image:\ /Cleanup-Image /RestoreHealth /ScratchDir:C:\windows\temp /source:esd:J:\sources\install.esd:6 /limitaccess
It didn't work.
I wiped it out and did a clean install.
Windows 10 seems to be easy to crash and hard to fix.
