Windows XP SP3.
system registry cannot load hive file: \systemroot\system32\config\...
Microsoft says to start Windows with CD and choose R for repair console, then give chkdsk /R command.. But there was not such option...strangely.
I tried to enter into the installation, the installation started and I've not stopped it because I believed it will replace corrupted files....
But it created a new installation.... the new one starts with no problems but no software installed... the other when starting asked me to check the unit C: for errors.... the process completed but again blue nag screen and automatic restart.
What I've to do for avoiding to reinstall all programs?
