OC Dual-Booting Questions

OC Dual-Booting Questions

So essentially I have iMac19,1 working on Big Sur with iservices and everything, but I just want to be able to boot into Windows as well. So I'm following the dortania guide which I will link below on how to do this, and I'm stuck. It says to "expand WindowsSupport.dmg and place it somewhere Windows can get." Does that mean to put the decompressed files in the USB drive in the resources? Also, it says to run an exe file, so I am completely stumped here. Was I already supposed to have installed Windows? I have two drives, one with Big Sur and the other one is an empty exFat drive I chose not to touch because I don't want to lose Big Sur. What should my next steps be?
