Question about upgrading Windows XP to Windows Vista? Answered
I am trying to upgrade a Windows XP Pro system with Service pack 3 to a Vista Ultimate system with the end goal of then upgrading to Win 7. Again the intention is to do an upgrade, not a clean install. This particular OS started life as a Win 95 system. Was upgraded to Win 98 then 98 second edition and then finally to XP. It has run on multiple motherboards and processors and many many hard drives. But I have hit a snag.
Vista ultimate will not give the option of upgrading. And by the way, this IS the upgrade version. It says so on the box and on the DVD. The option to upgrade is there but it is grayed out and a note says that it needs to do a clean install. If I wanted to do that I would skip Vista and go right to 7 to start with. So something is causing the install process to not want to make the upgrade. I am thinking it might be the service pack 3 of XP since the SP3 came out after Vista did. But I can't find any information about it. After all this is more than 10 years in the past. I am of course working off a clone drive so I can experiment and would just uninstall SP3 to try it but the uninstall is not available. As far as I can figure a repair was done using a SP3 disk of XP and that eliminated the uninstall. Now I can try doing a repair with a SP2 disk of XP in order to roll it back to SP2 but that might cause it to become unbootable and if not would for certain cause it to need to be activated again, which now will not happen over the internet but requires that you call somebody in India and read long strings of numbers back and forth to each other. I would hate to go through all of that and discover that it still will not upgrade. So the question is: is anyone familiar with this upgrade process and is there a way to force the upgrade option? By the way, I have both the 32 bit and 64 bit versions of Vista and the XP is a 32 bit version. So that should not be the problem. Any thoughts about this?
