Can't delete unwanted System partition

Question

Hi everyone, I'm having troubles deleting an unwanted partition (D:) from my SSD. I've had a Windows 10 installed on it (D:) previously and for one reason or another it malfunctioned and I had to install a fresh copy of Windows 10. Which I did on a different partition (C:). Installation was a success. C: is now a default partition. But I can't delete the original D: now. I've tried Disk Management and Power shell, but none worked. This is a screenshot from Disk Management.

When I try to delete volume/format I get the message that I can't delete system partition and that D is in use. How is it in use and how to delete it?

Hi RoseIdol

If you right click that D Partition in Disk Management, what options are available to you, is the Delete Volume option active?

If not, click your Start Button, then just type msconfig and press Enter

Please post a screenshot of the boot tab of that utility . . .

Hi. Yes, Delete is available, but when I click it, it warns me that D: is in use therefor deleting it can be damaging to my system.

As for msconfig, C: is current and default.

Drive D: looks like holding your Windows installation and your program files. It is your System drive. Are you really sure you want to delete it?
