    I don't know if I want to do the clean installation again. It would be the 4th time regarding Windows 10.

    The clean install will set your partitions and make sure it is bootable. Restoring the C partition will restore all of you programs and settings.

    When you do the clean install, make sure no other drives are installed and delete all partitions until it says unallocated. Then install. It will set the partitions it wants the way it wants them. Restoring the C partition will restore everything. Unless you have a real bad driver or a hardware problem, that should solve any boot issues you have.

    You may try starting in safe mode to see if it will boot before doing that.

    This entry (path \WINDOWS\system32\winload.efi) indicates that you are using efi.
    If you can boot it and get to login screen then I think the problem is you might have some corrupted files within C Drive. Try run from Admin command:
    dism /online /cleanup-image /restorehealth&sfc /scannow&pause

    Win 10 Pro (1703)

    M.2 SSD.
    A thought from something I've been through (which may be totally irrelevant, but easy to test!)- I have 2 disks, 1 being a M2 SSD (system disk).
    What I found was that the CU viewed my SSD as Disk 1, whereas the AU (and presumably earlier) viewed it as Disk 0.

    I had problems if either I upgraded to the CU, or clean installed the CU. None with the AU.
    When clean installing the CU, I noted a couple of very very brief warnings on the restarts about not find a boot source (too fast to catch - two short lines).

    However, the PC booted normally (which is not your case). The problem was with advanced startup options e.g. Safe Mode. (BCD error reported).

    As an experiment, try booting from your installation disk as if you were going to clean install, and when you reach the point of choosing which partitions to delete, check what disk number is displayed.
