Hello, I've just bought a second hand tablet PC which came with a copy of Windows XP Tablet edition on it. There is a COA with a CD key stuck to the bottom but the recovery CD wasn't supplied. According to the System Properties screen, it contains "Windows XP Tablet Edition 2005 Version 2002 Service Pack 2" I also have a CD containing Windows XP Tablet Edition 2005, already updated to Service Pack 3. Ideally I'd like to wipe the drive and install this, but I'm not sure if the CD key on the tablet PC will be compatible with the version on the CD. I've already tried installing the two side by side on seperate partitions to test, but for some reason the laptop refuses to boot into the GUI part of the installation, and won't even display the boot options. My next step is to just format the whole thing and try installing from the CD. However if the tablet PC's CD key doesn't work then I'm stumped, as I have neither the correct CD to match the CD key on the tablet, nor the CD key for the CD (it's being used on another machine)! Does anyone know if I'll be able to install the OS, or will I be stuck with a Windows-less tablet pc?
