Hi. I have been trying to get this boot camp thing working for FOREVER!!
For like 3 months I have been on almost everyday trying to figure this out.
I made a video on my problem - YouTube - What do you do when this pops up on boot camp?
And when somebody helps me with that problem , what do I do first to boot camp so I can get sony vegas soon?
I am like so ready!
I have tried seven downloads ( including apple site ) and it says the same thing for every time I download it.
I've also tried parallels .

And I have a mac

You have an old Beta version of Bootcamp; Beta versions always have expiration dates, and yours has expired. Bootcamp now only works under Mac OS Leopard (10.5), and is included with Leopard. If you don't have Leopard you're out of luck with Bootcamp.

Parallels will work with Tiger (10.4.11) or higher, but has pretty high system requirements so if you have an older machine you're unilkely to be happy with the results. Personally, I'd want at least 2Gb of RAM to run any virtualization solution. In addition to Parallels, there's VMWare Fusion and VirtualBox.

What model Mac do you have, what are the specs (RAM, processor speed), and what version of the OS are you running (10.4.x or 10.5.x)?
