LKBEN10763: Error "Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode" upon installation of Windows Server 2008 on Virtual Machine
Although 64-bit CPU and functional 32-bit VMs, no Windows Server 2008 installation possible on VMWare
Intel BIOS - processor options are set to "Virtualization Technology" disabled
VMWare ESX Server, Dual Intel Xeon 2.5GHz, HP ML350 G5: Installation of Windows 200.
After files have been loaded, the Boot Manager stops with the following screen:
"Windows failed to start...
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next".
3. Click "Repair your computer."
Info: Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode"
In this case, shut down your computer and enter your System BIOS. On above mentioned server it´s under "Advanced Options" - "Processor Options" - "Intel VT: Virtualization Technology" --> this setting has to be enabled (and is disabled by default).
On other computers the menus might differ, but with Intel CPUs/Chipsets this setting should be alike.
VMWare does not need to be reinstalled after changing this BIOS setting.
