hm if that helps:
I have same than you but:
Instead of installing bactrack 2 I have installed in windows xp the "virtual machine" VMware Workstation" and I emulate Backtrack 2.
Even better I actually emulate the live cd, meaning no installs needed!
Its very good I can even "pause" the VMware, turn it off, remove the cd, turn windows xp off, start in again, reput the cd, "unpause" and here we go, I have everything that I was doing up again!!!
