dual boot is possible and easy on Mint
assuming it’s not like Pop_OS! right, Boot up the ISO when you get to select the partitioning it should detect that windows exists and be able to configure it for dual booting [Choosing “Install Mint[Linux] Alongside Windows”] (which exists and does well on Ubuntu and it’s deravitives like Mint, Only I know Pop_OS! could be problematic, and it basically configures grub so you can select Windows or Linux, however I would still recommend the dual drives method or Another PC or stuff like tha5m)
