Here is a free and open-source tool to write a raw disk image file to a removable device (say USB or flash drive). The tool is named Win32 Disk Imager.

Although .dmg is a macOS disk format, there are a number reasons of why you'd want open them on Windows computers. Here's how to get started.

So I thought I'd use the MS Windows 7 USB/DVD installer tool to make a bootable flash drive of the .IMG file. Unfortunately, the tool only works with ISO's not IMG's. Next I tried Win32 Disk Imager.

Couldn’t Mount File, The disk image isn’t initialized Press Win+X and choose the Disk Management option. Choose the Action tab. Select the Attach VHD option.

Windows is frustrating, nuff said. How does an Apple Disk Image file, aka .DMG, not being able to open natively on Windows make Windows frustrating?

An IMG file can represent different types of data, such as hard disk and partition backups, which are not compatible with the conversion process for optical disc images.

iPhones can capture photos and video in high-efficiency formats which is great for image quality but can be a headache to open on your Windows PC.
