your post has anything to do with trouble upgrading from Vista Home Basic to Premium, the original subject of this thread. Then Bob's answer above isn't relevant.
Please start a new thread. And can you please post the full and exact litteral error message. Somehow I don't think it doesn't go like "trying to download the AIO_CDB software and need a disk to proceed", but something else.
What kind of disk, and why don't you just put it in?
If I read through http://forums.techarena.in/showthread.php?t=708162 I find a relation with HP All-in-ones indeed. It's quite understandable that after the first phase of installing it needs to do something at boot time. If it can't do it, because you don't provide the disk, it's quite possible it doesn't work. So I think this revolves about what disk?
Maybe, if you tell more, we can tell you what disk. Otherwise I would advice you contact HP tech support telling them you have some trouble installing their driver under Vista. Where did you get the driver from?
Hope this helps.
