\windows\system32\config\System file missing or corruptHi everyone,
I have a Toshiba 1135-S125 with OEM Windows XP Home Edition, and it only came with 3 recovery cd's. It did not come with the original Windows XP cd.
I also had a problem with missing or corrup \windows\system32\config\system file, and, after trying many different ways, I followed part 1 of KB307545 with a Windows XP Professional edition, the only XP version I could find at the time.
After I copied system, security, software, sam, and default files from repair folder to config folder, the computer restarted to windows; however, it had a totaly different look. First, my login icon was not there; apparently, by doing this process, Windows erased my configuration because there was a new icon named owner. After I clicked there, I got to my desktop, which was also altered because it did not have all my desktop icons. Finally, since I had access to the C drive and was able to see my files, I tried to save my important files to my USB memory stick or to a CD, but I did not have access to any peripherals.
After some thought, I decided to backtrack my steps because I reread the KB and it said that I should do it with the same Windows XP cd version. After I reloaded the "old" sam, system, software, security, default files, I restarted the computer, and indeed I got the same message Windows could not start because a \windows\system32\config\system file is missing or corrupt. To this I said OK! I am back to square one, and that was what I wanted.
Then I followed another thread suggestion, which said to only replace the system file and exit. To this point, I still only had the XP Professional version with me; therefore, I did just that with the XP Pro, which is replace just the system file and restarted the computer. To my surprise I got another error message which reads:
Isass.exe error message
Something along the lines of: the system could not verify the password at time of authentication.
After a few seconds, the message goes away and the computer restarts to the same message, so it goes into a never ending loop again.
After that, I said I will go back to the recovery console and recopied from the repair folder to the config folder the other files security, software, sam, and default because at least I felt much better to be able to read the info in my files. To this, when I inserted the XP Pro again and got to the recovery console, I found a question, which I was able to bypass the last time by leaving blank and pressing enter. The question I get is: "enter the administrator password:"
I never set up a password, much less at this point of crisis. Yesterday, 4/17/07, I got a whole of a Windows XP Home edition and tried to get to recovery console from there. I thought that by trying with a different version of XP, I will get a chance to go to the command prompt without a password, I was wrong!!! I found myself stuck in the same spot asking for the admin password.
This is my first time in this forum, please be patient with the lenght of my posting; I tried to detail as best as I could so that someone that knows about these issues could know in advance what I've tried; therefore, he or she could have all the tools to help.
I tried Toshiba and Microsoft Customer Service and they both declined help. I also tried CompUSA, and BestBuy, and they both said that a total windows reload is necessary. I have too much important data that I did not back up, and I can not lose.
Thanks a million in advance for your help, anything will help.
