Repairing a Black Screen Hyper-V Virtual Machine of Windows Server 2012 or Windows 8

This is just a quick tip for repairing a Hyper-V Windows Server 2012 guest virtual machine if you ever encounter the Black screen of nothingness. I recently experienced a couple of Hyper-V Windows Server 2012 guests that were only showing a black screen and I could not get access to the underlying operating systems. I wanted to document the trick that I used to repair these VMs.

  1. You need to use either an installation DVD or an ISO file of the underlying Operating System. I simply pointed the virtual machines’ cd drives to the server 2012 installation ISO.
  2. You reset the virtual machine and press any key to boot from the DVD or Iso file.
  3. Choose the option: REPAIR YOUR COMPUTER
  4. Choose the option COMMAND LINE
  5. enter C: to receive a C: prompt instead of the X:
  6. Now, you want to repair the bootsector so you will use the command

      Bootsect /nt60 C: /force

  7. reset the virtual machine, and hopefully you will see the blue login screen this time. In my case it took two attempts of entering the commands but it worked for both virtual machines. There is a /SYS switch that can be used also with the bootsect command but in my case I didn’t need to use that just Bootsect /nt60 C: /force did the trick.

Update on OneNote update KB2760600 problem still waiting for response.

I have notified Microsoft about this issue and it is being investigated internally. They have kept it pretty quiet so far, but I am sure there will be a response eventually. In case anyone doesn’t know what the problem is, it goes like this… After a Windows 8 Pro computer with Microsoft Office 2010 32 bit installed, the Windows Update from March 2013 KB2760600 is attempted and the user is asked to reboot. Upon rebooting, all other updates install smoothly, yet there is one last update that refuses to install and reboot the computer. The screen looks like this:

OneNote update KB2760600 hangs on restart

KB2760600 hangs on restart

. In fact, this has happened everytime I reboot my computer even after hiding the update, and if I check installed updates, this update is listed as installed, but I know this is the problem, because if I unhide the update and check for updates again, this is the only update that shows up.

Some users on the Microsoft Community forum have suggested that turning off the Print Spooler Service has fixed this problem for them, unfortunately this has not eradicated the problem on my system. (I have tried it twice). Now my system may not be normal because I have Microsoft Office Home Premium 2013 also installed alongside Office 2010, but this should not be an issue. I have not had much time to really dive into this problem yet, as I am currently enrolled in WGU and have been spending all my time studying for exams and trying to swiftly move along in my studies.

Here are some links that reference people also having this problem…



If any of the solutions here work for you, then you are lucky. I have tried them all and everytime I reboot I have to forcefully shutdown the computer again. Anyway, hopefully this may be answered on a future episode of Defrag on Microsoft’s Ch.9 since I have forwarded the issue to Gov Maharaj and Larry Larsen.

EDIT: Apparently, it has come to light that many of the people reporting this issue actually have HP printers installed. I have not confirmed this yet, but some people have said that they uninstalled their HP Printers / HP software and then the update installed. Updates will come as soon as we verify this after testing.

Windows Update KB2760600 Hangs in a loop forcing Hard Shutdown on Restart.

I have been dealing with customers who have been unable to get Microsoft’s OneNote 2010 security update KB2760600 to apply to both Windows 7×64 and Windows 8×64 systems that have Office 2013 and/or Office 2010 installed. This is nothing new however, as one of last year’s One Note update also caused the same exact problem.. In fact, if you google OneNote update hangs you can see that this has happened often in the past with OneNote updates. However this time, it is affecting many more users, and I am determined to get to the bottom of why this is happening.

After I personally experienced a never-ending loop of a Windows 8 Pro computer hanging for hours while attempting to update, I began doing some research and contacted Microsoft’s Windows Update team, and the Security Response team, and I found this article on Softpedia I am still waiting for a response from Microsoft.

The interesting part of this is that many of these affected systems have both Office 2010 and Office 2013 installed side by side, or a 32 bit version of Office 2010 on a 64 bit version of Windows 8. However, Windows updates have been mostly installing without issue for the last couple of years, with a few exceptions. But why are the OneNote updates causing problems. Perhaps this update was pushed out too quickly without the proper amount of testing.

Internet Explorer “RT” changes its policy towards Flash content tomorrow…

Starting with tomorrow’s Patch Tuesday updates, Internet Explorer in Windows 8 `metro’ version and Windows RT will now allow all sites to play Adobe Flash content, except for a new “Blacklist”. This is a complete reversal from the original whitelist approach that was in effect until tomorrow’s updates. What this means is that now most sites will be able to play Flash content, unless the site is Blacklisted and placed in the new updated Compatibility view list. What this update will do is actually enable Windows RT and Surface users to be able to access many sites that they have not been able to access in the past (without hacking the Compatibility List). Most likely, the reason for this change is that Microsoft has received many complaints from developers who may have been negatively affected by the Whitelist, and have been complaining to Microsoft that the old method was perhaps confusing to users, or just took too much effort to get Microsoft to whitelist their sites in order to allow tablet users to access Flash content on their devices.

This will mostly leave only Apple’s Ipad and Iphone users in the remaining frustrated users who cannot access the still largely popular Flash content enabled sites. Android users are able to get Flash content on their devices if they are technically adept and have found ways to install Adobe Flash on their Android devices. (Android discontinued Flash player many months ago, but there are still old downloads available of the now defunct Flash player for Android.

New Services in Windows 8 and Server 2012

Here is a list of new services in Windows 8 and Server 2012 that were not present in Windows 7 or Server 2008. I tried searching for this information online and could not find a dedicated list anywhere of just new services, so I figured I would post one in case someone else was curious.

1. Background Tasks Infrastructure Service – Coordinates execution of background work for WinRT (Metro) applications.
2. Claims to Windows Token Service – Service to convert claims based identities to windows identities. (Not installed by Default)
3. Device Association Service – Enables pairing between the system and wired or wireless devices.
4. Device Install Service – Enables a computer to recognize and adapt to hardware changes with little or no user input. Stopping or disabling this service will result in system instability. (This seems like it is the same as the old Plug N Play service.)
5. Device Setup Manager – Enables the detection, download and installation of device-related software. If this service is disabled, devices may be configured with outdated software, and may not work correctly. (Device Driver Automatic Update)
6. DS Role Server -This service hosts the DS Role Server. (This service is used by Domain Controllers in place of DC Promo.)
7. Hyper-V Data Exchange Service. Provides a mechanism to exchange data between the virtual machine and the operating system running on the physical computer.
