I have created extra partitions when I wanted to make a dual boot with Linux OS and Windows. I have had both Linux Mint and Ubuntu installed. After the second installation, I am not sure which of the partitions are used by Linux and which ones are used by Windows.
What I want to do, is simply get rid of all partitions, besides the ones used by Windows, but (I know it sounds dumb) I can't seem to find out which ones I can delete to go back to the original Windows boot (or if this is even possible without making a clean install).
I hope someon can help me out here. Here is a screenshot of my partitions:
As this is in danish, I have added some translation for the names of the partitions.
(Of course I realise that C: and D: are used by windows, but otherwise I am not completely sure)
