I was deleting some antivirus' as directed by the CA tech help people as I was trying to install the new CA internet security suite 2010, and something bad happened and now all I get when I turn it on is this; windows could not start because the following file is missing or corrupt.\windows\system32\config\system I dont have the original setup CD-ROM. It is windows xp. I have tried the F8 button to start in safe mode, no good. CA gave up and said I should take it to a technician, any ideas?
