My husband tried to upgrade from vista 64 bit to windows 7 64 bit on an HP pavilion dv4-1275mx. He's getting a screen that says upgrade not successful. Your previous version is being restored. Except it isn't. It just keeps trying to reboot over and over. I tried the system restore disc I made when we bought it and it says something about system restore won't work while the computer is in a limited state or something. Anyway, it didn't work. What should I do now. I don't have a vista cd--it came installed.w
I believe i heared some problems with upgrading 64 bit.
The only thing what i could say is the following;
I would say that is a method.
Check whether there is a special partition with an image of a fresh OS inside the BIOS.
Perhaps it is called something like recovery boot or similar.
