I am not good with laptops, I dont even have one but I don't really see why not! Personally though, I like Windows XP better then Windows2000 and WinXP Pro only has a few more security features! So personally...You either have:
A) Take my answer and just go for the installation.
B) Just keep Windows XP Home on your Laptop
C) Wait till someone who knows about laptops replys
If you take my answer and want to install 2000 or XP Pro, I'd personally go with XP Pro!
Of course, It depends on what your using the laptop for! If your gonna use it for Internet, Mail and IM's ... I'd say just keep XP Home!
