I've recently upgraded to a faster system but when I try to install my WINXP the keyboard locks up and wont let me go any further with the install. Also when I try to swap the hard drive from the old system to the new one I says it doesnt recognize the file system of the drive. I know they cant expect you to buy a copy of WINXP every time you upgrade to a new system by locking it in to one computer only even though it says for use on one computer only. Any experience *version is Home*. Also tried to put my WIN98 in but couldn't find the ref code. Any way to find this out?
