Linux

This is the way. My advice is to add a second hard drive to your pc and install linux on that. Distro hop, install arch and break it horribly, swear at your printer, learn. Then when you screw up, you’ve lost nothing, you can switch back to your “‘ol faithful” and get the job done. What will eventually happen is you’ll find yourself spending more time in linux than windows until you almost never boot it up.

If you do it this way, there’s really only two things to worry about. 1) if you’re using mbr or want to still use mbr with uefi, you’ll have trouble dual booting cleanly and will probably want to reinstall windows. You can’t break anything, but you can’t dual boot from both methods (or at least I’m pretty sure I’ve never owned a motherboard that can). 2) when installing linux, learn and be careful about what drive contains windows - don’t ever pick that drive when formatting and partitioning. Bonus points if it’s a different brand and size - makes it almost impossible to pick the wrong drive. When using a single drive for dual booting, there’s much more opportunity to make a mistake and break your windows install if you’re not familiar with partitioning and boot loaders.

I literally can’t think of a way to break windows if you keep the above in mind, and then you can “make the switch” gradually.
