Re: Change BIOS boot order

Any error messages ?

Try it like this

$spec=New-ObjectVmware.Vim.VirtualMachineConfigSpec
$spec.extraConfig+=new-objectVmware.Vim.OptionValue
$spec.extraConfig[0].key="bios.bootDeviceClasses"
$spec.extraConfig[0].value="allow:cd,hd"
Get-VM  |%{  $_.ExtensionData.ReconfigVM_Task($spec)
}
