I was trying to boot up a VM on VirtualBox, testing Ubuntu 19.02 but was faced with the error below.
The VirtualBox error reads (in clear search-able text):
Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).
The issue has got to do with Hyper-V (Microsoft’s version of HyperVisor) being installed/enabled on your system. You can either remove it in Programs and Files, or turn it off in command line. I would strongly recommend not uninstalling, so here is the less tedious way through command line:
- Open cmd with administrator rights
- Type in bcdedit /set hypervisorlaunchtype off
- Restart your computer
This should solve your issue when booting up.
Hope it helped!
