Buy a $30 SSD and put Windows on it. Boot to SSD when you want to use Windows, and put it down the booting order list in BIOS, so Linux always gets booted by default.
You will hear less about dual booting in Linux community because Windows loves to destroy GRUB bootloader, and also Windows is just becoming more and more annoying so there is a “nudging” or push to adopt Linux, forcibly or otherwise.
