My virtual machine Win XP showed an error message of NV4-disp error. I swiched the start up drive from Mac Leopard to WinXP and started again. However, I got the black window without any response from WinXP to the keyboard (such as F8, Ctrl-C etc). Now I even could not start Mac OS. Is there any key strike allow me to choose the OS before my computer load any OS? Thank you very much.
