Hi, i've been using windows vista home premium 32 bit for a while now for gaming but when i set up bootcamp I made the silly mistake of only partioning the hard drive 32gb to vista. With the up and coming release of the sims 3 in a couple of months and the fact that I am playing flight simulator x a lot I wondered if I could bump the partition up. I have the oem version of vista which I understand can only be used once? (correct me if I am wrong) I don't really want to be calling microsoft up but if that is the only way then I will have to. If I can't then how well do you think a game would run off an external hard drive connected to my iMac via USB 2.0. Many thanks in advance, Jack.
