Forgot to include the boot/system volume. It’s a lovely time waster when you’re dealing with disk images that are hundreds of gigabytes in size that have to be copied over the network. 😆
I’ll add Disk2hvd screenshots when I get a sec.
Situation gets slightly more complicated if you had multiple drives in your system when you installed Windows, of course. Installer might put system volume on a different drive, so you’d have to image more than one drive to get a working system. Might get a little confusing as to which volumes should go in which image. There’s a tool called GWMI that might help with that since afaik the volume guids don’t show up in the Windows Disk Management snap-in.
Edit: The promised screenshot. In my case, I knew the volume labelled SYSTEM resided on the same disk as my C: drive. Probably don’t have to include the recovery partition, strictly speaking, but I did.
When you figure it out, please let me know.
