Windows 7 Restoring partition drive permissions

[SOLVED] Restoring partition drive permissions

Hello,

I was tweaking some security permissions on my partition D and removed the options "Authenticated Users" and "Users", now I can't access it, even though I'm an administrator. After some time playing with it it seems I can't find how to add those two permissions back like it was. Can anyone help me or guide me?

Many thanks!

Partition C and how I want partition D to look like (or how it probably was before I **** it up):

Nevermind, solved by digging some more into the settings.
