So, if I am following this correctly, you had no problem activating a different version with the same serial.
But it's not strictly legal or M$ doesn't care?
I think Jelly's main concern is that he wants to stay legal on this.
I just got my free Vista as part of the feedback program and it included separate discs for 32 and 54 and a different serial for each one.
And Vista 64 bit (hale, for that matter, the 32 bit version) have coma a lonnnnggg way from the lack of driver nightmare days.
I was shocked at how easy 64 loaded on the Maximus Extreme rig.
Still think XP SP3 is the kaschizzle personally.
Although I do admit to loving the DreamScene and some of Vista's other treats..
haven't loaded NV graphic drivers yet, but so far easy as pie for drivers.
Jelly, booting from separate HDDs doesn't take any longer than booting from different partitions.
Either way I think VistaBootPro is a necessity.
