So, has anyone installed Vista Premium/Ultimate Upgrade edition against an XP Pro box resulting in a dual-boot instead of overlay?
Details of question:
Microsoft is really making things complicated. First, you have 4 primary editions of Vista (Home, Premium, Business, Ultimate). Next, you have 3 product types: Full Retail, Upgrade Retail and OEM.
I assume OEM is limited to a single machine install--but it is otherwise similar to Full.
I'm considering taking advantage of the Family discount issue (buy Ultimate, get up to 2 copies Premium for $50 each). Ideally I would like to get Ultimate Upgrade for $249 instead of $399 for full.
QUESTION: For upgrade version, everything I'm reading says you can not do a clean-install (ie: inserting XP cd to prove ownership). I have XP Pro now. I've also read from the limited deail articles that you must upgrade your OS. What precesisely does this ential? Can the upgrade version be used to install a dual-boot with the existing XP (on a separate partition)?
I absolutely do not want to install literally on top of XP as this would seem to be foolish to me unless XP was just freshly installed too (and even then, I would be disinclined to do this).
