How do I get Windows 7 to install on a full 3 TB HDD?

Thanks everyone, much appreciated. Giving this a shot now. I already try converting to GPT once already and it worked, but still only showed 2 TB, however, the steps listed your link Newteki have a few added steps I did not do.

Here goes nothing, thanks all, will be reporting back soon, hozzah!
