Windows 8 Release Preview and Windows Server 2012 Release To Manufacturing (RTM) / Release Candidate fail when starting for the first time after the installation (2021887)

  • 28 Ratings


After installing Windows 8 (64bit) Release Preview or Windows Server 2012 Release Candidate on an ESXi 5.0 Update 1 host or the VMware Workstation Tech Preview, you experience these symptoms: 
  • When starting for the first time after the installation, the virtual machine stops responding and displays a black screen with a white status ring
  • You may see this stop code:

    Error Code 0xc0000001

  • Restarting the virtual machine does not resolve the issue


This issue is resolved in ESXi 5.0 Patch 03 (Build 768111). For more information, see VMware ESXi 5.0, Patch ESXi500-201207401-BG: Updates esx-base (2019108). You can download this patch at the VMware Patch Portal.

: This issue is reported not to occur on VMware ESXi 5.1

To resolve this issue, use one of these workarounds:
  • Change the virtual machine to use EFI instead of BIOS.
    1. Right-click the virtual machine and click Power > Shut Down Guest.
    2. Right-click the virtual machine and click Edit Settings.
    3. Click the Options tab.
    4. Click Boot Options.
    5. Click EFI under Firmware.
    6. Click OK
    7. Power on the virtual machine.

  • Add vmGenCounter.enable = FALSE to the .vmx file of the virtual machine.

    1. Right-click the virtual machine and click Power > Shut Down Guest.
    2. Right-click the virtual machine and click Edit Settings.
    3. Click the Options tab.
    4. Under Advanced, click General.
    5. Click Configuration Parameters.
    6. Click Add Row.
    7. Under name, enter vmGenCounter.enable.
    8. Under value, enter False.
    9. Click OK to save the changes and then close the window.
    10. Power on the virtual machine.

      Note: The workaround involving adding the vmGenCounter.enable parameter to the virtual machine .vmx file may cause the new snapshot protection for domain controllers introduced in Windows 8/Windows Server 2012 to stop functioning. For more information, see the Microsoft Technet Article Active Directory Domain Services (AD DS) Virtualization.
