Over the weekend when my Windows 10 decided to completely go nuts. Ok it was my fault, as it happened after some exploitation attempts. But during the re-install I ran into a small issue. When trying to re-install on my NVME drive the setup kept stating that “Couldn’t create partition or locate an existing one in Windows 10“.

In regards to that error there were some hints out there about using diskpart to clean/”resetting the disk” which I didn’t want to do, as I had things I wanted to keep on other partitions.

Fortunately I got away with only deleting the all the Windows related partitions on that disk. Namely I deleted the windows partition itself & 2 recovery related partitions – so all I had left was the data partition. After doing that my windows installer stopped throwing that error and went on without any issues.
