How to restore my boot camp partition after replacing my SSD

I recently upgraded the internal SSD in my MacPro. Before putting in the new drive, I created a disk image of my boot camp Win10 partition. In fact, just to be safe, I backed it up in two ways -- I created a dmg file in Disk Utility, and I also imaged it using WinClone. Now I'm trying to restore my Windows 10 partition and the Boot Camp Assistant is asking for an ISO file, and it won't accept the dmg file. What should I do? Thanks.

Good work on the backup. You need to reinstall Windows before restoring the system- basically, follow these instructions again: Install Windows 10 on your Mac with Boot Camp Assistant - Apple Support

Then, WinClone should let you restore the image you made.

Bootcamp does not have a restore function.
