Windows 10 Creators Update Fall 2017

As seen by FOS.

This system arrived with Dell Win10 OEM installed and FOG was used to install Win7 Pro. Then (some time later) Win10 OEM DVD was used to reinstall Dell Win10 OEM, and then was updated to Creator’s update with a forced download from MS. The point being this system was not a clean as delivered install of Win10 OEM.

Win10 Fall 2017 upgraded from Win7 Pro

As seen by FOS

This system is a bit of an anomaly. This system had windows 7 pro installed and then was upgraded during the free Windows 10 upgrade program. To complicate things a bit more, this system has 4 hard drives. There are 2 raid arrays using the onboard intel “fake” raid controller. The smaller array is comprised of 2 SSD in a raid 0 configuration. The second array is comprised of 2 465GB hard drives in a raid 1 configuration. Looking at lsblk I can’t really make heads or tails of how the disks are constructed. The 223GB drives are the ssd drives. and the 465GB drives are the rotating hard drives. FWIW: This system is in legacy (bios) mode.

This is the second attempt to collect a bit more information on this same system.
https://forums.fogproject.org/topic/11070/disk-drive-geometry-and-partition-layouts-for-well-know-os/9
The issue I was running into is that the computer was running RAID on intel’s “fake raid” (i.e. hardware assisted software raid). When I collected the data the first time I did not take into account I needed to have the RAID kernel drivers enabled using the kernel parameter mdraid=true as outlined in this tutorial: https://forums.fogproject.org/topic/7882/capture-deploy-to-target-computers-using-intel-rapid-storage-onboard-raid So that explains why I had a hard time understanding the disk structure as it was being presented to FOS. I also discovered (for some unknown reason) when I setup this computer I set the data drive up as raid 0 (striping) and not raid 1 (mirroring) like I thought. Hmmmmm…

So the following info is being generated with the mdraid kernel parameter enabled.

This system is a special case too. In this setup there is the windows disk that is on a pair of SSD drives behind an LSI raid controller, and a pair of HDD behind an Intel “fake raid” controller. AND a M.2 sata high speed scratch disk. This systems is a native uefi system with Dell Win10 OEM as the base OS.

Well that wasn’t very effective. It seems like for half of the partitions FOS could not mount them and the other half FOS thinks they are dirty because I just shut down the computer, but with Win10 shutdown is not shutdown. I’m not too concerned about the dirty bits, since I know those are valid data partitions. I’m more interested in why the gpt boot and recovery partitions are not mountable. I don’t think they are protected by bitlocker, actually the boot partition should never be encrypted by bitlocker anyway since its needed to actually boot the system.

Edit: more info from this mystery machine.
