I forgot to mention... most distros give you the option of wiping the drive and installing linux alone, installing along side windows, or resizing the drive however you want and shrinking the windows partition.
If you don’t want or need the windows any longer, choose to wipe the drive and install it. If you think you may still want to boot into windows later, choose to install linux along side windows.
Have fun
Good point. I woild dual boot till I was sure I liked Linux, then wipe the partition clean if I chose to go back to windows, or wipe windows partition clean and expand the Linux partition if I wanted Linux. It’s all pretty easy to do with granted.
