Boot Configuration

Docker requires Hyper-V enabled whilst VirtualBox requires Hyper-V disabled.

In the past, I created multiple boot configurations so that I could switch between VirtualBox and Docker.

Nowadays, I just run with Hyper-V enabled and rarely use VirtualBox.

Enable / Disable Hyper-V

To create a boot option with Hyper-V disabled:

C:\>bcdedit /copy {current} /d "No Hyper-V" 
The entry was successfully copied to {ff-23-113-824e-5c5144ea}. 

C:\>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off 
The operation completed successfully.

To create a boot option with Hyper-V enabled:

C:\>bcdedit /copy {current} /d "Hyper-V" 
The entry was successfully copied to {ff-23-113-824e-5c5144ea}. 

C:\>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype auto 
The operation completed successfully.

Check Boot Time

To check the last boot time:

C:\> systeminfo | find /i "Boot Time"
System Boot Time:          08/03/2019, 20:00:57

C:\> wmic os get lastbootuptime
LastBootUpTime
20190308200057.500000+000
