This isn’t the best or most popular way to do it, but: https://learn.microsoft.com/en-us/windows/wsl/install

There is a way built into windows to deploy and use Linux from inside windows.

It’s not the most pure experience, but it’s a way to make sure you have something like a feel for how some parts work before jumping in any deeper.

A bootable USB stick is another way to try before you commit. Only reason I might suggest starting with trying it the other way first is in case you run into issues connecting to the Internet or something you won’t feel totally lost. Having to keep rebooting back into windows if you have a problem can be frustrating, so getting a little familiarity with a safety line can help feel more confident.

Issues with a USB boot are increasingly uncommon, as an aside. Biggest issue is likely to be that USB is slow, so things might take a few moments longer to start.

From there, you should be pretty comfortable doing basic stuff after a little playing around. Not deep mastery, but a sense of “here are my settings”, “my files go here”, “here’s how I fiddle with wifi”, “here’s how I change my desktop stuff”. At that point a dual boot should work out, since you’ll be able to use the system to find out how to do new things with the system, and also use it for whatever, in a general sense.

If it’s working out, you should find yourself popping back into windows less and less.
