You can "dual-boot" if you set up for it. There is no real(??) difficulty in having your machine set up so that you can run either Win or Linux, depending on which you need for what you're doing at the time.

Normally, you have to restart the machine to change systems - although I've heard urban rumors about "on-the-fly" switching. It may be workable.

If you have the "tech-smarts" to run Linux, it should be a snap. If you already have WinXX, it's probably good enough for anything you might keep that you'd need it for, so just (try to) buy all your new software in Linux versions.
