I am getting the following from windows xp: Windows could not start because the following file is missing or corrupt windows\system32\config\system When I place the original windows xp pro disk in my iMac it does not run the disk so that I can make any repairs to the windows xp system. Is there a setting I need to make in parallels 4.0 so that it will run the disk in the xp side?? Any help would be appreciated! John
