The October 2017 Update – “Inaccessible Boot Device”

Posted by Mikael Nystrom on October 11, 2017

Also known as:

KB4041676 -

KB4041691 –


Affected systems:

This only affects systems that are managed trough WSUS and the patches was approved at the same time as the “delta” updates also was approved. Those updates was never intended to show up in WSUS, they should be deleted/Declined. You should NEVER have Delta updates in WSUS. It was a “woops” somewhere. But if they were approved, and distributed, and download, and installed at the SAME time as the full patch, then you are affected

These should be declined, and they should be gone at the next sync.


After installing the update and reboot, the pc will not boot, instead it gives you ”Inaccessible Boot Device”

Official Solution:

Currently the official solution is to contact Microsoft Support, but it is possible to use DISM.exe or PowerShell to remove the updates or reverse back a folder name.

read about the issue here (from Microsoft)

Information regarding the Delta’s from Microsoft in a forum.

The Quick fix Solution:

A very nice MVP manage to figure out how to remove all the updates using DISM, and yes, it does work like a charm!

(update: If this is a VM, you might need to add more memory. We have found that you need at least 3GB of RAM for WinPE to use larger scratch space.)

Other ways to fix it is:

The idea is to rename the WindowsApps folder and that seems to work for some

OSD – Workaround for ADK issue in 1703

Posted by Mikael Nystrom on May 16, 2017

The issue in ADK 1703 is that you cannot mount a WIM file in MDT/ConfigMgr, due to a signing issue with the WIM Mount Driver when running a system with UEFI and Secure Boot.


Michael Niehaus did found a workaround today, and that is to use the existing WIM mount driver that is already in the system.

Nice to Know – New feature in Windows 10 Creators Update

Posted by Mikael Nystrom on March 29, 2017

One of the new features in the upcoming version of Windows 10 (Windows 10 – Creators Update) is the Windows Defender Security Center, as you might expect it is defender, but it also includes a nice little health check


In this case, there is something wrong, maybe we should take a look…


Seems that I have an issue with a device driver, hmm, need to fix that


Let us run that and see what is wrong…


Big surprise (not really), one of my virtual network adapters are turned off.

That should give you an idea what the new feature is all about, pretty nice, pretty cool.

Windows Server 2016 – Create a NAT network using the Hyper-V switch

Posted by Mikael Nystrom on March 3, 2016

In Windows Server 2016 (TP4) and Windows 10 1511 it is possible to create a Hyper-V Switch with NAT functionality, including publishing rules. The purpose is to run containers, but it can of course be used to run normal virtual machines. This means that you can very easy build an infrastructure environment with access to Internet and reverse without having a virtual router or firewall, pretty neat IMHO. Currently, the only way to create the switch is using PowerShell, but hey, I don’t mind…

Create the Switch

The following command will create a VM Switch for NAT usage with a subnet of The net result will be a switch and an Internal network adapter with the IP address

New-VMSwitch -Name ViaMonstraNAT -SwitchType NAT -NATSubnetAddress

Create the NAT rule to get out

The following command will create a NAT rule for all machines connected to the Switch that uses the default gateway to get out.

New-NetNat -Name ViaMonstraNAT -InternalIPInterfaceAddressPrefix

Create a publishing rule

The following rule will open the “firewall” and redirect traffic on the hyper-v host port tcp/80 to the machine on the VM Switch with the IP address to tcp/80

Add-NetNatStaticMapping -NatName ViaMonstraNAT -Protocol TCP -ExternalPort 80 -InternalIPAddress -InternalPort 80 -ExternalIPAddress

Check if it works

You can use the following PowerShell commandlets to see the configuration after it has been done.

Get-VMSwitch will show you the switch with SwitchType NAT.

Get-NetNat will show you the NAT configuration bound to the switch.

Get-NetNatStaticMapping will show you the publishing rule.

Get-NetNatSession will show you current NAT sessions.

OS Deployment – Allow PXE deployment to the same MAC Address by configure SMS_DISCOVERY_DATA_MANAGER in ConfigMgr, or How to deploy Windows to shared docking stations and usb network adapters

Posted by Mikael Nystrom on January 29, 2016

This is very simple, when you deploy a device uisng PXE, ConfigMgr will inventory the MAC address, but that will prevent that mac address from being used once more unless the hardware inventory is executed after the machine has been deployed and removed from the docking station (similar)

The fix:

  • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Components \SMS_DISCOVERY_DATA_MANAGER on the primary site server
  • Add a MultiString entry called ExcludeMACAddress
  • Add all Mac Address to ExcludeMACAddress

For a complete story I strongly recommend you to read the following post:
