Maybe it’s just me and maybe it’s that my experience is quite old, but I would say it is not worth messing with dual boot if that’s what you’re thinking. It can be a big hassle to get working, and has some chance of screwing up your Windows side during installation.

Instead, buy a new SSD or hard drive and swap it into the place of the old one, then do a clean single-boot Linux install. I prefer Debian MATE which has a Windows-like UI, but again there are lots of choose from. If something goes wrong or if you don’t like it, you can swap drives again and be back where you started.
