Basically, I'm dual-booting windows 10 with Ubuntu, but for the life of me I can't remember which partition it's on.
I ran the disk management tool, and it showed these results.
Normally I'd be able to tell, however on this laptop it has a recovery partition on drive D: (although I only have one HDD inside of it, if that helps)
I'm assuming it is the 11.64gb / 7.92gb partitions but I don't want to make an assume and mess up the boot.
Screenshots:
Apologies if the formatting isn't very good, I've never used this website before.

I also forgot to mention in the original post that I ran os-uninstaller to uninstall the ubuntu OS. I probably should've mentioned this but my mind blanked.

The Ubuntu partition would be formatted in ext4, but none of your screenshots show one.
I would guess it was installed on the 11.61GB partition, and OS-Uninstaller formatted it as NTFS. You can go back to Windows, delete the 11.6GB and 7.9GB partitions, and expand C into the empty space. (The 7.9GB partition was Ubuntu's swap space.)
