Boot Configuration Data store editor

The Bcdedit.exe command-line tool modifies the boot configuration data store. The boot configuration data store contains boot configuration parameters and controls how the operating system is booted. These parameters were previously in the Boot.ini file (in BIOS-based operating systems) or in nonvolatile RAM entries (in Extensible Firmware Interface (EFI)-based operating systems). You can use Bcdedit.exe to add, delete, edit, and append entries in the boot configuration data store.

Check hypervisor launch

Check that hypervisor launch is enabled in the boot configuration. You can validate this by running an elevated powershell.

bcdedit /enum | findstr -i hypervisorlaunchtype

If you see "hypervisorlaunchtype Off", the hypervisor is disabled. To enable it, run the following in an elevated powershell.

bcdedit /set hypervisorlaunchtype Auto
