If you are using a new ASUS Motherboard with the EFI and Windows 7 or Windows 8 and want to setup Hyper V in Windows 8 or setup a VmWare Image you may eventually run into the issue where you will see an error saying Virtualization support is disabled in the firmware in most cases this is the default setting of the ASUS EFI motherboard where Intel Virtualization Technology is disabled by default and required if you want to run 64bit VM’s.
To enable this feature, reboot your computer and go into the ASUS EFI Bios Utility, make sure you go to advanced mode, click on the Exit/Advanced Mode button and make sure you go to Advanced Mode.
From here you will click on the advanced tab, and you will have to scroll the slider bar down to where you see the Intel Virtualization Technology option, make sure this is enabled then save changes and exit the ASUS EFI Bios.
Click Turn Windows Features on or off link in the left sidebar.
Check mark the Hyper-V option and open it up to make sure both options are checked.
Note, if only Hyper-V Management Tools is checked and Hyper-V Platform is shaded or grayed out it means it still isn’t supported and something else may not be right.
Now Hyper-V is enabled and you can use Hyper-V to create an Ubuntu Image on Windows 8, or now you can use VMWare Player or VmWare Workstation 9 and install an Ubuntu VM in Windows 8 without issue.
