Uninstalling peppermint 7 on windows 10

I have been trying find out how, so, i am trying here. I had windows 8.1, and upgraded to windows 10 awhile back. Wanted to play around, so, i managed to get peppermint 7 installed along side mt windows. It was good, but i had a lot of trouble getting around and understanding the ubuntu os. I have been trying to find the best way, that iu could understand, to do this. It talked about deleting linux partitions, but i cannot tell oine from the oither. I would like some help, in telling me what to do with this. Thank you,
