I have a brand new Dell Notebook which came with Vista Home Basic SP1. I tried to upgrade it to Vista Ultimate but it would not give me the upgrade Option. Thinking that the ultimate DVD does not contain SP1 I went ahead and created a slipstreamed DVD with SP1. Again I tried the upgrad and again I'm not given the option.

Anyone has any ideas?

You have to boot it in windows and not in the bios

I'm not sure what you mean bye that answer, but I'v tried both from windows and booting from the dvd

1.boot up vista
2.put in vista ultimate disk
3.a window should popup with the insall button in the center
4. Click install and the upgrade button should be there above the clean install

Thanks for your response. That is exactly what I've tried, but the upgrade option comes up greyed out and therefore not chooseable

Have you tried intergrating the latest updates

perhaps theres an update it needs

Thanks, I'll look into that
