So I got a Mac. And no, I don't want any of the PC bullshit questions and aggrivating comments... I just want to know an answer too something.

I tried to use boot camp so I can simply boot into windows and use my zune and visual basic.net.. Well it turns out that half was through setting up the partition it took the ten gigs i asked it too, and got rid of it... popped up an error saying i needed to restart, and wahlah. 10 gigs of my originally 20 free, gone. And no, its not unallocated or whatever, its just not there anymore. I wan't to get it back so i can use windows and finish this dumb project because microsoft doesn't have the balls to make their software universal. I mean for god sakes they just updated office and will never update windows media player for mac. itunes is universal? why not zune? they have like all of the marketshare so why do they bitch?
idk...
I can't change their minds, but I can dual boot.

Some Mac genius please just tell me how to get this back.
Thanks.
Jack
