@dolf Great to see you read my reply as it was meant - a technical elaboration and not personal offense! 
Why do you choose resizable if you intend to make a backup copy of this laptop? This backup is supposed to go back to the same machine with the same disk and there shouldn’t be a need to use resizable image type for that reason!
Because it’s the default option, and when in doubt, default options are usually safe. In this case it’s not. I understand why this was a bad choice. Lesson learnt.
This choice is years old, so not something we changed lately. It was even before I started to help working on this project, so I can just guess. I think it’s the most used image type because people want to be able to image to different machines and it is working in most cases. While you can use FOG for backing up machines it’s not the common aim of this software. Again, not saying it’s perfect but we try to make it as save as we possibly can.
May I suggest that there shoud be some help text or a link to the wiki in the GUI that warns users about the pros and cons of different types of images?
Would you help us write the texts and find a good way to place them in the web UI so people definitely see them but don’t get annoyed?
Did you disable Windows 10 fast boot and properly shutdown before you started the capture?
I always shut down from the command line before capturing. Is that sufficient? As far as I understand that disables fast boot for the next boot.
Yes, good you knew about this. I was under the impression that this might have been caused by a unclean filesystem because of fast boot that got somehow corrupted.
There is no way we can prevent users from all different kinds of situations. We try to make FOG with as much care as we can bit it’s like a swiss knife and if someone uses it the wrong way no one will blame the factory or engineers for having created a dangerous tool, right?!
This is true!! But maybe the default option should be the safe(-r) one?
What is the default option of a swiss knife? I suppose it’s opening the hinging blade. I think you are on the right track with saying, we should add help text for people to let them know about the pros and cons of the different choices.
I am sorry I can’t give you really good advice on the actual problem. Without having the machine in front of me I fear I could give instructions that could make things even worse. But let’s give it a try anyway. I suppose you have some parts of the image capture on the FOG server. Take a look at /images/dev/.... There should be a folder named by the MAC address of this computer. Take a look at that. Do you have files d1.mbr, d1.partitions and d1.minimum.partitions in that. Please post the contents of the later two here - they’re just text.
