Unable to restart after Win10 Reset

I have a Surface Studio and yesterday, Win10 did an update on it. After that, my screen was split in half, like Win10 saw half the screen as one monitor and the other half as a second monitor. I was trying to fix it but as I was checking the options, my cat jumped up on my desk and whatever option was selected (I think it was to extend displays) was selected. I chose to revert but for some reason, that was ignored, so now my monitor was black and there was nothing I could do to get it back. After doing some searches and trying to get to the bios or using Shift-P to try to get rid of the ghost monitor (never got that to work), I said, forget it and reset Win10 (that was a mess in itself to get there since I had to connect up a wired keyboard first). I left it running and went to bed. This morning, I get up and the screen is black so I press the power button and eventually it comes up with the black screen, Windows logo and the circling dots. That stayed for a couple of minutes, then went to a gray screen and the Win logo, the screen flashed, and then the system powered off. I turned the power back on and the same thing happened. After several more attempts, I'm at a complete loss. My second PC updated with no issues (OS Build 18362.1139). Any assistance would be appreciated.

Clean install from a Windows 10 USB flash drive?

That's what I'm thinking I'll have to try next. Of course, that means I have to get dressed and go outside ...

I did eventually get it to try to repair any errors causing it to not start up and got the message that it couldn't make the repairs. I went and bought a USB drive as none of the one I had were large enough and it now says that is installing but I'm skeptical. If it works, good, if not, I may see if I can reformat and try again or just replace the HDD with an SDD.

The best way to completely wipe the drive of everything before you do a clean install is:

When you get to the very first windows setup screen, press Shift + F10. If it is a laptop you may need to press Shift + Fn + F10. This will open a command prompt. Then run:

Code:

diskpart
lis dis
sel dis # <-replace # with the actual number of the installed HDD, probably 0
clean <- this will erase the disk selected above, make sure it was the installed HDD
convert mbr
exit
exit

Then proceed with the custom install option. When you get to the screen showing drives and partitions, you should see the HDD with nothing but unallocated space. Highlight the unallocated space and click next to finish the install.

In case you need to recover important files please comment.
