This question is related to this other one: Blue screen 'inaccessible boot device' on Windows 10

I now have two PC with a blue screen on startup with inaccessible boot device.

Both of them are of model HP Compaq 8100 Elite Small Form Factor. I suspect this is due to the last update KB4015217.

For the moment I deactivated the Windows Update service on the remaining computers of that model.

In the computers that cannot boot into Windows, I can access the command line via Troubleshoot > Advanced options > Command Prompt.

How can I use that command line to uninstall a specific Windows Update ?

dism /image:D:\ /get-packages gives me the list of packages installed, but dism /image:D:\ /remove-package:Package_for_RollupFix... fails with Access denied.

    Have you tried to use your Windows 10 recovery disk to boot into Windows 10 and remove that update? You can also create a System Repair Disk to troubleshoot.

  • I only have the original installation disk. I do not have a recovery disk. Commented Apr 12, 2017 at 13:37
  • Any reason you cannot make one?

  • How is it possible to remove an update, if I'm not able to boot into the Windows installation ? Commented Apr 12, 2017 at 13:38
  • No, I will make a System repair disk to see what I can achieve with it. Commented Apr 12, 2017 at 13:39
