Hi I am a newbie an need some help.
I have just revcovered my laptop after a hard drive change and used the product recovery disks to get back to windows xp professional.
I had to skip the windows setup page as I had video driver problems.
I just dont know how to get back to the windows setup page as my country language is wrong.

e.g I want the @ sign and I get ". I know it is a U.s thing, but how do I get back to change it to U.k? thanks

 

Go to Control Panel, Regional and Language Settings, Regional Options Tab and change the language to English UK.
