VirtualBox boot error

[Xenoverse]

I'm attempting to run Windows 7 (64 bit) as guest from Ubuntu 12.10 with VirtualBox (installed through Software Center). When I tried to start Windows for the first time (with install disk in drive and boot order set to CD/DVD first), I get

FATAL: No bootable medium found! System halted.

What do I need to do to get it working?

You do not set the boot order, thats for host only. You select it from the guest screen when installing.

I got it now. For some reason when it gave the first boot prompt and I select the drive it doesn't work, I had to go to Settings > Storage and change the IDE controller to the proper drive. Working now though
