Windows Server 2012 (and Windows 8) on VMWare ESXi 4.1

Due to the limitations of ESXi 5.1 i don’t want to install one in my Network. So i’m searched for a solution to run Windows Server 2012 (and Windows 8) on ESXi 4.1. After surfing around on the net i finally found a working solution in the VMWare forum.

The following steps are done on own risk:


  • Create a  new VM over the vSphere Client.
  • As “Guest Operating System” i used Microsoft Windows Server 2008 R2 (64-bit)
  • If you finished the creation of the VM download the follwing bios file and upload it to your ESXi datastore
  • Move the bios file to the folder of the new VM
  • Now open the .vmx file of the new VM and add the follwing lines
    • bios440.filename = "bios.440.rom"
    • mce.enable = TRUE
    • cpuid.hypervisor.v0 = FALSE
    • vmGenCounter.enable = FALSE

Now start the new VM and install Windows Server 2012 (or Windows 8) :-)
