Dual boot XP and Vista upgrade registration

[cgp13]

I have a somewhat complicated two-part question. I just bought a new computer when I went to reload VAC it told me to e-mail to get a new code, that's not a problem but when to do it is my question. Before I do this I'm wondering what the code that is generated by the program to send in is based on, my hardware or my software setup? I don't like the way the system arrived and plan to reload it completely creating a dual boot XP and Vista setup. I'm afraid if I send in this code now and then reload two operating systems I might run into problems. I could use some advice on the best way to go about this and what order to do what, so I don't run into any problems. Your help would be greatly appreciated.

I think VAC does not really care so much about your hardware, and it's more for compatibility on your OS.

I would wait till you get your operating systems back on the way you want then ask for a new code. I am dual booting too,but I hardly ever use XP anymore, and purchased my key for vista I'm gonna guess that my code will not work in XP, but I have never tried. Probably a question for Shift_E.

Planning a new build myself very good question.

Good luck
