If you are referring using a Windows PC to dual boot into Mac OS whether it is High Sierra or Mojave it isn't easily accessible to a novice. If you are referring to using a Macintosh/Mac OS system you can use Boot Camp to install Windows fairly easily. As for the prior, you can run Mac OS on a Windows machine with Hackintosh software but that is a pretty lengthy process. I hope this helped and I apologize for an extremely late response
