Part 1: Download macOS or Mac OS X DMG File
The first step is to get the DMG disk image file for the version of macOS that you want. You can get a copy of the latest macOS version from Apple download portal or App Store here. There are also several other direct download sites that offer various versions of Mac OS X in DMG format rather than the standard APP format that runs on Mac. Since you're working in a Windows environment, you need the DMG rather than the APP file.

Part 2: Format USB Drive to GPT (Optional)
Updates (Dec 8, 2020): The latest version of UUByte DMG Editor is able to format the USB automatically, so this part is optional. Follow the steps only when the burning process failed in Part 3.
Mostly, the USB drive was formmated to FAT32 in default when being shipped out from the factory. However, FAT32 can be only used for installing OS with legacy BISO, which doesn't work for macOS. So the next step is to format your USB drive in the GPT partition style in order to burn installation files to the desired USB drive. You can do this in Command Prompt as admin. In elevated Command Prompt (Ctrl+Shift+Enter), input the following series of commands followed by Enter after each line:
Diskpart
List disk
Select Disk X (X stands for the USB drive name that appears after the previous command)
Clean
Convert GPT
Create partition primary

In previous tutorial, we wrote a post about creating macOS Catalina bootable USB on Mac, which is a simple tool and there are a couple of free tools to complete the task. You can even use the built-in tool Disk Utility and dd command to do it without installing any third-party apps. However, the situation is much different on Windows 10 because macOS install file (end with .dmg) is not supported by Windows OS. Unlike ISO image, there are few tools on Windows that can handle .dmg files. That's the most challenging part!
So in this article, we will show you how to create macOS bootable USB on Windows 10 and targets macOS Catalina specifically, which is the latest version of Apple macOS and it is easy to download the install file. This will be a great help if there were something wrong with your Mac and a fresh install was demanded. Also if you were a Mac enthusiast and can not afford the price, then it is not a bad choice to build a hackintosh with Catalina.
Before heading to the details of each method, please make sure you have downloaded a copy of Catalina OS dmg file and a working USB drive with more than 12GB storage.
Method 1: Create macOS Catalina Bootable USB on Windows 10 via DMG Editor
There are more than one solutions to create macOS Catalina Bootable USB on Windows 10 and we will go with easy one first. DMG Editor, a popular app developed by UUByte, is a multi-functional and cross-platform image burning tool that works on Windows, Linux and macOS. It supports creating bootable USB from popular image files, including dmg, iso, zip, img. And it has full support for Linux distros and old versions of Windows OS. macOS support was not available in previous versions. But now, the latest version of DMG Editor adds better support for macOS dmg file. Let's get a try first.
Step 1.Go to UUByte official website and download Windows version of Etcher from there.
Step 2. Run the executable file and complete the installation process. After that, insert an USB drive in Windows 10.

So if you were going to use Etcher to create macOS Catalina bootable USB, make sure testing it on a high-profile Windows 10 PC or laptop.
Method 2: Convert .dmg to .iso and Create macOS Catalina Bootable USB
macOS Catalina install image is distributed in .dmg format and Windows 10 has no support. Hen it is almost impossible to read such files in conventional ways. So in this part, we will convert macOS Catalina dmg file into ISO and create a bootable installer by burning the ISO file to USB. This can be done with the help of third-party software.
To execute the method, you need two software. First, you need a special software to convert dmg to ISO. Second, an ISO to USB burning software to make bootable USB from ISO file. To demonstrate, we have used 7 PowerISO & UUByte ISO Editor to create macOS Catalina bootable USB from Windows 10.
