Hyper-V cannot be installed
The processor on this computer is not compatible with Hyper-V. To install this role, the processor must have a supported version of hardware-assisted virtualization, and that feature must be
turned on in the BIOS.

Text on the help page
To install and use the Hyper-V role, you will need the following:
An x64-based processor. - Hyper-V is available in x64-based versions of Windows Server 2008specifically, the x64-based versions of Windows Server 2008 Standard, Windows Server 2008 Enterprise, and Windows Server 2008 Datacenter.
Hardware-assisted virtualization. This is available in processors that include a virtualization option; specifically, Intel VT or AMD Virtualization (AMD-V).
Hardware Data Execution Protection (DEP) must be available and be enabled. Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).
Additional considerations
The settings for hardware-assisted virtualization and hardware data execution protection are available in the BIOS. However, the names of the settings may differ from the names identified above. For more information about whether a specific processor model supports Hyper-V, check with the manufacturer of the computer.
If you modify the settings for hardware-assisted virtualization or hardware data execution protection, you may need to turn off the power to the computer and then turn it back on. Restarting the computer may not apply the changes to the settings.
