I just had this problem myself. Turns out I was trying to install a 64 bit OS on a virtual machine that I created before I enabled virtualization in the BIOS. The solution was to delete the VM and create a new one. If virtualization is enabled, you will see Windows Server 2008 (64 bit) as an option when you create a new VM.
