How to repair windows10 system disk when MS tools fail

One downside to that is that personal data on the partition(s) restored also revert to that at the date the image was created.

In these respects System Restore and in-place upgrade repair install are superior- when appropriate and available of course.

On my most important desktop PC, the personal files are on a separate drive to to the system drive. I've only ever had to recover the system partitions so the issue has not arisen. Anyway, I also use File History set to copy personal files every hour.

So I guess conclusion for this thread is:
if in-place upgrade repair install from MS does not work, there are no other tools which can help you?

In your situation I'd first boot from a live boot disk which includes a disk check program such as Crystal Disk Info, or perhaps the portable version of Hard Disk Sentinel and run a check on the physical disk.

If the disk is failing and that is the cause of the problem, there's no point trying to repair the O/S.

If the disk is good, then as suggested, create and boot from a Macrium Reflect bootable disk and run its useful 'Fix boot' utility - which is better than Windows' Startup Repair.

An in-place upgrade repair is only possible if you can log in.

Post #12 answers your questions

1. - NOT AVAILABLE - you can't boot.
2. - YES. (Fix boot) - as I've just told you in post #12.

Before attempting to repair, check the disk, as I believe I said before.

You need a live boot disk e.g Gandalf's with Crystal Diskinfo on it as I recall. Create that on another PC.

If ok, create Macrium's boot disk and then run Fix boot and advise result.

Start with those.

Are any of the 3. party boot repair tools like windows boot genius, tweaking repair etc. worth trying on top of MS tools and reflect fixboot?

No, there is no reason to try any of those.
