Well done! Hope you wont have to do it again for a while now!
I have to reinstall the operative system on my computers from time to time, and it's a chore every time. One of these days I have to remember to buy Norton Ghost (Basically, I can copy a fresh install with it, and when it turns sour later on, I can just overwrite it with the copy of the fresh install and just do the updates since the copy was made).
