Hi, I just installed VB yesterday and it was running well. But today it stops working and keeps giving me error message. I tried to turn off the virtual machine platform but doesn't work. I have no Sandbox (Windows 10 Home). Can anyone please help?

Code: Select all   Expand viewCollapse view
Failed to open a session for the virtual machine Ubuntu 16.04.6.

Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}



Edit: Added hardening error log and my Windows 10 build is version 1903 (OS Build 18362.239)

00:00:02.363651 HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
00:00:02.417381 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

It seems that you have Hyper-V enabled. Look at the topic "I have a 64bit host, but can't install 64bit guests" for some Hyper-V enablers that we're aware of so far. You should disable all of them.

Thanks a lot socratis! I actually saw the list but couldn't locate a lot of those names so I thought they were all closed. I ran the command line you have written and can run VB again.

Glad you got it going. Marking as [Solved].
It seems that the "bcdedit" command line change is the most popular one! :)
