That ReactOS enterprise boot screen is great. It reminds me of standing behind my father's business's administrator, as he repeatedly crashes Win2k3 Server.(It booted for the secondary admin perfectly...) . I keep getting some modules_not_loadable_yet from freeldr, but, the machine boots and is perfectly stable. (As much as ReactOS can be, no BSOD).
Quick thought, dragossh. Macs use USB. USB is pretty new to ReactOS, but it is ironing out. Ask someone else that has a Mac to see if they have the same problem, seeing as Fusion (just googled it) is in beta. ReactOS is one step behind, but one step can be an awful lot. (Such as a canyon).
