The drive is fine, actually I got it cloned to another drive and it is working on it, there is no problem with current drive.
I forgot to mention that before I restored software and system hive from regback folder, I had uninstalled latest quality updates , so that it would fix the boot problem but it did not.
Now, the current problem is probably I used software and system files from regback folder, with could be a bit out of sync with current installed windows files. There might have been windows updates happened later than the taken automatic registry backups. I can send you the problematic sofware and system files. You might want to see which updates they had compared to current one...
