Vista/XP Dual Boot question

[Shakey_Jake33]

I have installed Vista, but am considering re-installing XP and dual booting.

Is it true my XP OEM key is basically invalid now I'm installed OEM Vista?

No, why would it?

I just thought this was the case - if this is not, cool.

i.ve read you need to have the older o/s loaded first or else it wont allow the dual boot screen to appear.
