Hi All,

I just migrated a virtualbox vm to a physical machine all went fairly well(I'm currently typing this on it)I'm currently running windows 8.1 the only issue I have is that the upgrade to windows 10 is showing "THIS PC CANNOT RUN WINDOWS 10" the reason for this is because it thinks I have the "VIRTUALBOX GRAPHICS ADAPTER FOR WINDOWS 8" still installed. I did do an uninstall of the vmguest additions and deleted the graphics adapter and installed the current nvidia drivers for my card. does any one know where the graphics drivers could be hiding so i can manually remove them or can I download the actual driver installer/uninstaller somewhere? Its not really a big problem but my ocd will not allow me to continue this way. So if a kind soul has any Idea I'll make sure to send lots of good Kharma their way!

The vm cannot see the physical card in the host, so there is no point in trying to install the drivers for it in the guest OS. The guest OS only sees the emulated video driver of the vm.

There is a "sticky" discussion on upgrading a vm to Windows 10 in the Windows Guests forum.

'Tis a V2P, the former Virtualbox guest has been migrated to physical hardware. Now the OS is running the physical PC and will see all the hardware.

If I recall correctly, the going recommendation to upgrade a guest to Windows 10 has been to uninstall the Guest Additions first. But did you do this before you migrated the guest OS to the physical hardware? Might be necessary to allow the upgrade. What does your Display Adapters section in Device Manager say?

As long as the machine has activated, an upgrade to Windows 10 from the Windows 10 free download media (not Windows Update) should work provided that the physical machine meets the hardware requirements. What the currently installed OS shows doesn't really matter because the upgrade actually does a clean install of Windows 10, then loads the drivers , then transfers the old files and programs which are compatible (and VirtualBox is not involved in any way).

As a worst case, you can do a clean install of Windows 10 and activate it using the Windows 8.1 product key.
