Disable Hyper-v in windows 8.1 pro error

hyper-vhypervisorwindowswindows 8.1

I am trying to disable Hyper-V in Windows 8.1 Pro 64-bit but it is not working.
I tried using Control Panel as well as by using this command: dism. exe /Online /Disable‐Feature: Microsoft‐Hyper‐V

But did not work.

During shutdown it does up to 30% disables and during boot time it gives message as Getting Windows ready ...% completed and then it shows:

We couldn't complete the features
Undoing changes
Don't turn off your computer

How do I resolve this error? or how do I disable Hyper-V in Windows 8.1 Pro 64-bit?

  • The log shows that Windows fails to update the boot manager:

    10:27:54, Error [0x018050] CSI 0000004e (F) Failed execution of queue item Installer: Boot Configuration CSI Advanced installer ({3eca0b00-79bb-42b9-8421-a26a5cbb37e4}) with HRESULT HRESULT_FROM_WIN32(ERROR_FILE_NOT_FOUND). Failure will not be ignored: A rollback will be initiated after all the operations in the installer queue are completed; installer is reliable (2)[gle=0x80004005]

    This happens when you use other boot manager like GRUB to dual boot Linux. Remove GRUB, uninstall Hyper-V and restore GRUB after doing it.
