I have my disk divided in two partitions and I think one of them is running windows but I don't know which one of them and how I can delete it. In my boot menu I can see a Windows bootloader which I want to delete but don't know how, I think it may be related because on my bios settings I couldn't find any option to delete it.
Sorry if this question is dumb or if I am using incorrect terms to describe what is going on.
