[SOLVED] How to merge D drive to C drive?

[zhshqzyc]

I reinstalled my Windows 10 from USB. It is obvious something messed up for my HP Pavilion 15 laptop. The C drive should be 900G and more. However it is small now. Please see the image at Annotation-2021-09-27-193953 — ImgBB (ibb.co) .

I want to merge D to C. Now I am using NIUBI free edition.

If you don't care about the contents of the drive, reinstall Windows and delete all of the partitions before telling the Windows installer to choose one.

There is a way to do it without reinstalling Windows, but it's a lot slower and I don't know if it'll actually work.

You have a 1TB drive plus an Optane module.
Please show a screencap of the actual full Disk Management window.

How did you install this?

This is a brand new install?
The easiest way is to start over.

Delete all existing partitions, leaving one blank space, consuming the whole drive.
Install to that.
