Windows 10 Boot Failure Error Code 0xc000000e

Windows tries to load but fails with blue screen.

Your PC/Device needs to be repaired
The application or operating system couldn’t be loaded because a required file is missing or contains errors.
File: \Windows\system32\winload.exe
Error Code:0xc000000e


I was unable to recover from this error! But Peter was able to -- highly recommended -- he knows his stuff: http://www.peterspcrepair.com/

Notes based on my limited understanding of the problem:

This was one of the clearest articles I could find.
However, my understanding is it's not a suitable fix for a UEFI SSD system drive.

This was one of the clearest articles I could find suitable for UEFI.

My results from command prompt: list vol

What tripped me up is I kept thinking the UEFI volume was the same as the system drive. I could assign a letter and see the files on my system drive (i.e. my C:\ drive with windows). But this is the wrong drive to use for bcdboot. The UEFI is apparently always FAT32. I "think" I should have been using volume 5. Volume 7 seems to be from my Windows 10 recovery disk.

So I should have been running (from command prompt) this:
sel disk 0
list vol
sel vol 5
assign letter=G: Note: G is a unique drive letter not already in use.

Restoring from a recent restore point did NOT resolve the issue. But was done before the boot repair above.

BIOS boot mode changed from "Dual" to "UEFI". Unclear if this was a necessary fix. My understanding is this was NOT necessary. PC had been working with zero issues for the past 3 months.
