Are there any errors during boot or is it just sitting at a blank screen? Which hypervisor are you using? Are the minimum resources allocated to the VM or is it using default values?

I am using Windows 7 Ultimate.I think there is no Hyper-V in Windows 7.I have installed Virtual Box.But I could not see 64 bit options of any of OS in the dropdown list.I have allocated maximum resources to the VM

Do any other VM's work?
