auto update damaged system file - won't start up
XP Pro Srv Pk2 loaded. Original mach was XP Home. Updated awhile ago and
it has been fine. Dell machine
Last night I downloaded windows update and when it rebooted black screen
saying "Windows can not start because the Windows\System32\config\system
file is corrupt or missing. You can attempt to repair this file by starting
Windows Setup using the original Setup CD. Type "r" at the first menu.
I may be in over my head. I have 3 CDs. Original setting for Home XP
setup, the CD upgrade to Professional XP and the Serv Pack 2.
At the moment I can't get to a screen to type or do anything.
I can get into setup to change the order of booting to the CD Drive but I am
afraid to mix up the system file from the original disk with the upgraded XP
Please help. I don't want to lose data on machine.
