The burn function has one of the highest success rates in the industry, which makes this an ideal utility for our purpose.
Created by the talented team of developers at Androidphonesoft, DMG Editor is currently the most intuitive Windows app for handling Apple's disk image format. Each of its functions have been tested on various Windows versions, with different types of DMG files and on different PC brands. This thorough testing means no wasted DVDs or corrupted files. As long as your DMG file is in good shape, you can directly create a bootable disk.

Method 3: Create macOS High Serria/Mojave Bootable USB on Windows 10/7
Another way to create macoS bootable disk on Windows is using a tool called DMG2IMG along with Windows command prompt.

Step 2. Type the following command and hit Enter: dmg2img [sourcefile.dmg] [destinationfile.iso]
Step 3. Now that the DMG file has been converted to ISO format, you can use the following command to burn it to a disk. Before that, insert a disk into the optical drive: isoburn.exe /Q E: 'C:UsersUsernameDesktopdestinationfile.iso'
Step 4. This command utilizes the Windows native disk image burner to burn the ISO to the disk in your optical drive. The ISO file can't be used directly in macOS, but it can be mounted as a virtual drive. Once you do this, you can convert it back to DMG using Disk Utility in Mac. You can then use this as your bootable macOS installer.
As you can see, this is a bit of a workaround because DMG files aren't natively supported in Windows. Likewise, ISO files aren't fully supported in macOS.
