I'm running Windows 7. I downloaded VM Virtualbox so that I can run some old non-game 16 bit programs (Excel 4.0 in particular).
I believe I loaded it correctly - ALERT: I am not a computer whiz!
When I click on the Oracle VM shortcut, the VirtualBox Manager comes up. On the left side is the XP logo. When I click on START, I get "No bootable medium found! System halted." There is some Youtube and other forums on this issue, but the items they say to do, I don't have. For example, they say click on Storage in the VM Manager and then click on something that I don't have.
