Duel boot help for caveman

Does anyone know a good way to duel boot with windows? Right now I gotta get to bios and turn off fast boot then manually select the drive with Bazzite on it. Then if I want window's I gotta enable fast boot and switch to the window's drive. For some reason window's won't launch if fast boot is disabled. I'm a bit of a caveman when it comes to tech though sorry if this question is something that's common sense to ya'll.
