    Are you sure you did the proper bcdboot command with the correct drive letters?

    Looks like my monitor (sans camera) . I haven't pulled the tape off the bezel either.

    It's a Samsung 27" C27F398 Curved Monitor. I love it though I wouldn't mind getting a 32".

    Thought I did. At the time I ran it, MBR partition was S: and NTFS partition was T:.

    bcdboot c:\windows /s s:

    Should I have used:

    bcdboot c:\windows /s s: /f ALL

    Now it's I: though Explorer doesn't show it.

    Doesn't say anything about EFI System partition though.

    Since you are I: and J: now it should be:
    bcdboot I:\Windows /s J: /f ALL

    You won't get an EFI System Partition because that can only be created on a GPT partitioned drive. UEFI computers will boot from any FAT32 partition that has the proper boot files in it. If you did not use the /f ALL option the first time, then you likely only wrote BIOS boot files to it, because that would be the default for an MBR drive with an Active system partition.

    I'm at 79% applying the image...

    bcdboot I:\Windows /s J: /f ALL
    \Windows is on J:, not I:.

    C:\Users\ztruk>bcdboot J:\Windows /s I: /f ALL

    Now let's see if this baby boots!

    Yep it booted into it! I'm using a USB 3 flash drive plugged into an adapter which is plugged into a USB C port. It really isn't all that slow for a flash drive!

    Okay, I'll go through it again tomorrow, I'm getting sleepy now, but it looks the same as what I've already done.

    What are your UEFI Setup settings?
    Secure boot, csm?
