Thanks everyone, I upgraded to the newest version of Fog, and had to do the following and now it works:
Windows 8.0, 8.1, and 10 (and most likely future Windows versions) have a feature called “Fast Startup”. This feature basically sets windows so that a hibernation occurs whenever the system is shutting down. This enables Windows to startup much faster than in past Windows versions. Because this feature is on by default, the windows OS partition has a hibernation file which prevents mounting and imaging via FOG, and also marks the OS partition’s “Dirty Bit” to ON. Even when hibernation and fast startup is disabled, the hibernation file remains and the “Dirty Bit” remains ON and these things causes problems. There are a few ways to fix/get around this.
Way 1 (clean method)
Disable: “Turn on fast startup”, located here: Control Panel (Classic View) -> Power Options -> Choose what the power button does -> Change Settings that are currently unavailable -> “Turn On Fast Startup & Hibernate”
Both of those settings should be turned off for use with FOG. They may be turned on at a later time via GPO or snapins.
Shutdown and then boot the system.
Then run this command from an elevated command prompt to disable hibernation and remove the hibernation file:
powercfg.exe /H off
Now you can shut down and reboot once or twice, and then capture your image via FOG.
