No OS error

[zsaberslash]

So I installed a visualization software on my parents computer and set up a virtualized Windows 7. I didn't have any installation disks for 7 so I told it not to look for it. It set up the machine and when I loaded it up it said:

FATAL: No bootable medium found! System halted.

I know why this is (No OS) but it's still quite cool!
