What Do I mean?

Well, back in the days when macOS 10.12 Sierra was released, the TransMac was not fully responsive, I was using this method. I was creating a Virtual Machine (VM), then I was creating bootable USB for macOS Sierra. The same method can be applied for macOS 10.15 Catalina on Windows, as long as you have a running Virtual Machine of macOS. It is fine even if you have an older version of mac such as Yosemite, as long as it is a mac, it can do the job. if you don’t know How to Install macOS 10.15 Catalina on VMware and VirtualBox on Windows follow the below links.

Here are the methods.

Step 2. Format the USB Flash Drive with mac Partition

sudo /Applications/Install\ macOS\ 10.15\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled —applicationpath/Applications/Install\macOS\ 10.15\ Beta.app —nointeraction

If the first command did not work the second command can do the job easily.
