Help partitioning my HD for Ubuntu

Hi, you may have seen my other thread about Linux asking which OS was better, decided I'm going to try Ubuntu for a bit.

I DL'ed and burned Ubuntu, but when I try and install it, and I get to the Partitioning bit, I get an error message. I can't post what it says right atm, but once I load it back up, I will tell you.

I'm backing up ALL my stuff, knowing that this COULD remove some, but I really don't wanna have to remove Windows, so any help for now would be deeply appreciated

Fixed, starting another thread though.
