One cannot upgrade from one language version of Windows
to another language version of Windows. You'll have to
purchase a "Full English Version" of Windows XP,
reformat your drive and install it "clean". An "Upgrade Version"
of Windows XP in English will not work unless you have an
actual English version of a Microsoft Windows 95/98/ME/2000
installation CD to use as a qualifier during the setup phase.
