I just recently upgraded my xp home to xp pro. Everytime I bootup the comp, it give me this option to boot with xphome edition or xp pro setup. Some how it did not give me the option for xp pro. However, when I choose the xp home edition it boot up to the xp pro. When I choose the xp pro setup, I get this error message " file missing or corrupt : <windows roots>\system32\hal.dll ". I just want to by pass this step to choose the boot up os and automatically load up xp pro. Any help will be appreciated.
