I upgraded to XP somewhere around a month ago. My uncle loved it so he wanted to upgrade from Win 98. My uncle, who isn't the smartest when it comes to computers, asked me to do it for him. At first, the installation was going fine, until a message that popped up saying something like "Windows couldn't start because system32/gal.dll was missing" or something like that and I had to cancel it. How can I fix this problem? PLEASE HELP!
