@Wayne-Workman The drive in this computer is a 256GB SSD. It is a GPT disk. The drive was originally formatted from the factory and has not been reformatted since.
I think we’re on to something here because as you said partition 2 of a GPT disk should not be resized under any circumstance. Partition 4 is the Windows partition and is the one that should be resized.
If I reboot the computer after the failure message and try again to upload the image it will go through as if everything is OK. Partition 4 resizes correctly and it appears to upload the image. When I restore this image to another system it is not bootable. I failed to mention this earlier but this has been happening ever since we did the first upgrade.
Is there any way to force fog to only attempt to resize partition 4?
