To start with the bad news. For now there is no solution. When Hyper-V is enabled, VMWare Workstation 9 simply refuses to install or to run. But there is a way to install and use VMWare Workstation 9 while having Hyper-V installed.
The trick is to create an extra boot option. Here are the steps to take:
At the command prompt, type the following: bcdedit /copy {default} /d “No Hypervisor”
The above command should say: The entry was successfully copied to {guid}. Copy that guid to the clipboard including the curly braces.
Now, type the following command: bcdedit /set {guid_hvoff} hypervisorlaunchtype off
In the above command, replace {guid_hvoff} with what you copied in step 2. The above command just sets a property in the boot entry that will not load the hypervisor on boot.
This way you can switch between the both of them on startup.
tried but failed.
says “the boot configuration data store could not be opened. access is denied
Have you run BCDedit as administrator? That should fix this error.
