I just installed windows 7 from scratch, on a partition which works fine in boot camp. Parallels seems to think it needs upgrading though, and it fails on the part where the upgrade process switches to the guest OS. Any way I can force it to just do its thing rather than bother with the entirely unnecessary upgrade?
Well, apparently I can upgrade to 5 for free now, so I'll get that and see if it makes any difference whatsoever.
