Not that I know too much about it, but XP doesn't recognise SATA drives and so the drivers for those have to be installed via a floppy disk during the install process.
However, thinking about it, attempting to 'upgrade' from Home to XP would not bother about the SATA drivers as they are already installed. But there are other pitfalls, eg;
http://support.microsoft.com/kb/292607 - "Microsoft does not support upgrading Windows XP Home Edition with Service Pack 1 (SP1) to Windows XP Professional without SP1".
Also, that OEM is a bit of a worry. Since OEM's are usually tied to specific machines, I have to wonder where that OEM disk originated from.
Perhaps others here will be able to give you better advice.
I'm trying to upgrade from Windows XP Home to Windows XP Professional, as the subject implies. I am so frustrated right now, that I want to scream. Here is what I have done so far.
I started off with Windows XP Home and Ubuntu 9.10 playing nicely together on my laptop. (I use nicely as a very loose term.) I was doing fine managing without Pro using 3rd party apps. I recently came into a new OEM copy of Pro. I initially tried to install this into Virtual box on Ubuntu, but without success. I then booted into XP Home. I tried installing it as an upgrade to Home. This did not work either. I eventually imaged both partitions and reformatted the entire drive as NTFS and cleared the MBR. I was unable to install Pro to a freshly formatted drive. I reinstalled Home from the HP recovery CD. I then tried to upgrade again into Pro. It did not work, yet again. Each time it fails I get the following error message:
"Setup cannot set the required Windows XP configuration information.
This indicates an internal Setup error.
Contact your system administrator."
Since I cleared the MBR before attempting to reinstall, this leads me to believe that the OEM copy of XP Pro might be lacking driver support for my HDD. (WD Scorpio Black 320GB 2.5" SATA) Anything I might have missed? What do you guys think?
