Windows 10 black screen boot.

Hello all, I've been having some trouble with my Windows 10 desktop. It's upgraded from Windows 7 if this helps, though sadly due to my issue as described I can't get any information on the installation for you.
How it works is as follows.
1.) I hold the power button.
2.)The Dell logo comes up.
3.)The words "Preparing Automatic Repair" appear.
4.)The screen goes to black. It's still backlit and the monitor light stays on, so it's not the monitor going to sleep.
After a while of this, I hold the power button to turn the system off.
Now I try it with a Windows 10 USB I made with the official Microsoft tool.
1.) I hold the power button.
2.)The Dell logo comes up.
3.)The Windows icon appears, then vanishes.
4.)A stretched out fragmented blue line appears alone for a while, then the Windows icon appears under this line.
5.) The loading dots appear and hang until I power it off.
This recovery USB has worked in every single other computer I put it in and booted. I even tried formatting and re-making the USB.
Lastly, I tried making an Ubuntu live USB.
This boots up to grub fine.
I can select Ubuntu and use it with no problems.
I can mount and view all my windows files on the internal computer hard disk.
While having a working OS convinced me my memory and processor are working, I still loaded the Dell bios option for testing hardware and it came back with no errors.
The last thing I did was check each partition of the main hard disk with the Ubuntu disk management. It was all okay but for one sector. This sector is a booting sector as expected, though I don't see how this would change my recovery USB working. The message is "Filesystem ESP on (Numbers) needs repairing.
Any help would be appreciated.
I know I can get my data back but the fact that I can't even get to the point where I could install a totally fresh copy of windows for no reason at all is infuriating. I have no desire to replace everything when I know that my future will hold OEM keys and other headaches if I swap the drive (And with linux being able to use the drive I know it can't be bad.)

I would like to report an interesting development. I was using a different keyboard on the computer, and during the normal loading screen, I pressed the numlock key because this new keyboard has a much brighter LED. To my total astonishment Windows stopped loading and just jumped right in. I have no idea what the cause of this is but once in I ran the Windows 10 repair tools and it said there were no issues. Now my computer works fine.

This happened before your post, though I am taking note of the tools you suggested in case of the issue cropping up again. I can't thank you enough for providing a list of free tools to help out.

- unfortunately not entirely true.
Either from a live boot disk such as Kyhi's or Bob Omb's e.g. run HD Tune Health and Error scan tabs, or from Windows if you manage to get that running.

A good point made, I am running the suggested tests.

Do you use disk imaging routinely as is so often recommended here? E.g. Macrium Reflect (free/paid) - include all Windows partitions. This helps you recover from many difficult situations- unbootable cases, disk failure....

As the case normally is, I considered myself far too proud to back up for data failure because that's something that happens to other people, not geniuses such as myself. I will of course be doing so once my backup drive arrives.



Thank you again for the assistance, I will be keeping these tools in my back pocket just in case and a backup at all times.
