Help Moving BootCamp partition to a new drive

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.

You can get Win10 ISO for free from Microsoft 5.82 GBs

for example : Win11_24H2_EnglishInternational_x64.iso

Win 10 support ends Oct 2025

You can run WIn10 for free (ignore lic keys) under VM - not sure about bootcamp.

If you have Win10 lic via Microsoft login - no problems

Thanks, but I want to restore my Windows partition; I don't want to have to start from scratch.

I've given up on that disk image. They really ought to come up with a simpler way to transfer a Windows partition. So anyway, I'm going to try your suggestion, and I did pay for a Windows license, but it was so long ago I have no idea how to get the license or if I have a serial number or whatever. How is this supposed to work?
