Hi folks,
I just tried to do an inplace upgrade of one of my Windows 2003 VMs. The VM is running on a ESX 3.5 Host with VirtualCenter 2. So I get an interesting error I can't explain. Before I'm able to start the Upgrade I get the following error message:
"Compatibility Report
- You must do the following changes before upgrading Windows
- This computer is not compliant with the Advanced Configuration and Power Interface (ACPI) standard. Windows must be installed onto a computer that supports ACPI. Contact your computer manufacturer for a BIOS update or install Windows on an ACPI-compliant computer."
I've a VM on the same Host running Windows 2008 without any Problems. I Also tried to remove the Windows ACPI components or to change the HAL. But so far nothing fixed this Problem. Any ideas on this topic?
regards
