ok. I guess I'll try it then.
I imagine I need to do the "Custom" installation when I receive Windows 7 , to wipe everything if it doesn't work?
Windows 7 should be here in an hour or two. If the old installation disc works, I can return Windows 7, and get the student discount. (such a ripoff, the "Upgrade" student price is $30, and I had to pay $180 since they don't offer any full installation discounts)
