I built a Windows 10 system image in VMWare Workstation that I gave a size of 64GB, so the image could be cloned onto multiple devices of any larger size. I was told that after cloning onto the target machine, I could simply open diskmgmt and refresh and it would pick up the true size of the hard drive. I have cloned this image onto my first target machine but it is not working. Disk Management is not seeing any unallocated space. It shows one EFI partition of 200MB and a C drive of 63.68GB and nothing else. This laptop has a 250GB drive, it should be showing me 186 GB of unallocated space?
EDIT: A workaround "solved" this. I actually shrunk the disk first, by 1024MB, and after that action it suddenly picked up that there was ~170 GB of unallocated space, at which point the C drive could be expanded. But why was this strange workaround necessary?
Have you cloned the disk via boot from Windows 10 install media, as described here?

Clonezilla is a Linux-based utility that sometimes has problems with Windows, so is not the ideal tool. Apparently it cloned your disk, just did it too exactly. By shrinking the disk you caused Windows to interrogate it for its architecture, so discovering the missing space. Clonezilla should have done it for you, but as I said it's not that good with Windows. – harrymc – 2019-07-26T17:18:19.620
