Okay I am trying to do an in-place upgrade Windows XP to Windows 7, via Vista, but I am running into a problem.
I put my Vista disc in for the initial upgrade but when I get to the part where it asks if I want an Upgrade or a Clean install, the upgrade option is greyed out, and there is a message on the bottom that says the following:
Upgrade has been disabled. -Windows cannot determine if another operating system is exists on your computer. Try repairing the boot configuration and then begin the installation again.
Can someone tell me why this is hapening and how to fix it?
Also, it is Windows XP Pro, to Windows Vista Business, to Windows 7 Pro, all 32bit which I checked the upgrade paths and this should work...
