Bootcamp Issues - PLEASE HELP!

Ok, I have had the most frustrating couple of days trying to get bootcamp to work, absolute nightmare.

First of, when I was trying to partition my drive it wouldn't let me, and it took about a day to work that one out, and then when I inserted Windows 7 for the installation process, it said 'Install disk not found' (and i'm sorry it was a download of vuze of windows 7 ) But my dad can get a legit one but it takes a few weeks and `i didn't want to wait that long! Ok, so I downloaded Windows off the internet, if your gonna lecture me about it then don't bother, not interested

Anyway, I downloaded a trial of Parallels and the windows image file worked fine, and I am running Windows perfectly off it, but I wanted bootcamp to play FSX through windows and this isn't possible through bootcamp (is it?!)

I burned windows onto a DVD again, the right way this time I think (using DVD-R) format, and the computer rebooted at the installation process of bootcamp, and I thought I had done it, at last, but low and behold I get a black screen with the message 'Cannot Boot - Code 5 Error' or something like that, definitely a code 5, and that where I'm stuck now.

Maybe I should try a different DVD format? run it off a flash drive? It cant be the windows as I am running it perfectly on parallels?

Any suggestions would be greatly appreciated, thanks in advance.
