I would also recommend Mint with Windows as a VM over dual booting. I find the workflow is better to not leave Linux but rather load the VM for the windows needs. This is especially with nonaggressive apps like modifying PDFs. If you were going to produce music or edit videos dual boot might be a better option.
I wouldn't recommend WinBoat for you yet. Its too new, and while I like what I've tested I want to see it in a year or two after it's fleshed out. At the end of the day you're running Windows in a VM anyways, so its pretty much the same thing.
