I get this message every time I want to use a Boot Camp VM for Windows XP Pro and after I shutdown Windows using Build 4128 that I downloaded yesterday. There was an archive thread about this that was never answered. Is this normal? This is such a nuisance, is anyone from Parallels working on it? (and this is in addition to the problem - in another thread - that Windows needs to be re-activated within days). For only owning Parallels for less than 24 hours, despite all the good press about it, this thing is a DOG when trying to use the Boot Camp partition. Beware.
