While I was starting my vm I got this error

Microsoft Emulated IDE Controller Error(Instance ID 83F863B-8DCA-9EDA-2CA8B33039B4): Failed to Power on with Error 'The process cannot access the file because it is being used by another process .'.

What's wrong with it?

  • Do you have the VHD attached to another running VM? – Michael Hampton Mar 29 '14 at 19:36

It's also possible for Windows to lock a VHD file. I ran into this by double-clicking on a VHD, which causes recent version of Windows to open it up like a folder. However, it appears that the system then holds a lock on the file, which prevents Hyper-V from using it to start a VM. Rebooting fixed that problem.

    Rebooting is overly drastic. Just open Disk Management and un-mount the VHD. – longneck Aug 5 '14 at 19:09

I had the same issues a few days ago:

Microsoft Emulated IDE Controller Error(Instance ID 83F863B-8DCA-9EDA-2CA8B33039B4): Failed to Power on with Error 'The process cannot access the file because it is being used by another process...

I tried to remove the USB Drivers and IDE - CD-ROMs. Re-initiate permissions again, but it didn't solve the issue.

I had to create a new VM and attach the hard disk. It solved the issue.

Hope that helps.

When you will click the virtual drive like computer\user\public\publicdocument\hyper-v\virtual machine\documents and settings the a new drive is opened in My computer. Right click the specified drive and "eject', then go to Hyper-V and start the Virtual Machine.

Very very simple. Simply go to vm setting. Then in the left pane just under the IDE controller 1 click DVD Drive and then select none. Job done.

Go the your Hyper-V Manager, locate the failing Machine settings, go to its virtual Hard drive, inspect the drive on the right pane and then reconnect the drive. Finish the wizard and your machine will start normal.
