Failing to boot after fresh Installation of Windows 10

I had the same issue and found a solution eventually. I tried all the troubleshooting tips, but nothing really helped. I took the M.2 drive from the computer, put it in another computer, installed Windows 10 on it, then returned the M.2 drive to the original computer and it just worked. My guess this is an issue of enumeration of drive order. Windows installer does weird things when the install drive is not the first drive in the list of drives (even if it's the only drive in the list). If I tried to install it in the original computer the installer said it's being installed on drive 1 or drive 2. But in the other computer it was found as drive 0. I'm guessing the USB drive took precedence in terms of enumeration on the original motherboard and some install files were installed on the pendrive and that is why it was not working. If you only have one computer, you might be able to install Windows 10 from a DVD since it's read-only, but it might be a bit difficult, since the image size is over 4.7GB in recent versions. You might be able to install an older version of Windows 10 and then upgrade it. But if you don't have an older image, you might find it a bit difficult, since Microsoft no longer distributes older ISO images. I'm not sure how to produce a cut down version of the ISO yourself, but I wouldn't trust downloaded ISOs from the internet from an unofficial source.

Let me be clear. This must be an issue with the Windows installer itself, since I was able to install Pop!_OS on the same computer without any issues.
