Anyway so I partion the hd and boot off the disk and it immediately gives me this black screen

2:
Please select boot option 1, 2

And thats it so thinking one must be install or something i press it, nothing so I try two again nothing haperns so i just swipe my keyboard the press them all and still nothing so i boou up with a keyboard pluged in (I have a macbook) and do the same but get nothing agein I also put it in my xp computer and try to do an upgrade but it has no startup and no xp files.
Thanx for reading, Sorry about the typos and please help!

Im not pirating its built into vista that you just type in the pommand prompt a code and they give you an extra 30 days evaluation wich you can do once then if its worth it Ill buy one
