Recovery Help

[bunghole@]

Recently, my windows installation became very buggy and I was shortly unable to load load windows at all. Also, everytime I ran a PLesk backup, the box would crash. I now have a new harddrive with the same version of windows installed, my second harddrive contains the old PLesk installation. My question is, how would I come about transfering the old PLesk information to the new OS Installation? All the directories etc are intact still, but I don't know how I'd come about doing this.

Thanks.
