A couple of days ago upon re-boot I could not get to the desktop because the following message came up. “Windows could not start because the following file is missing or corrupt. Windows\System32\Config\System You can attempt to repair by starting Windows setup using the original Setup CD-Rom, select ‘r’ at first screen to start repair” Doing as told did not work so it seemed a good place to put the Bootable Rescue Disk to work. In retrospect I think there was no reason to even bother with the Setup CD-Rom but instead have gone straight to the Bootable Rescue Disk to begin with. In using the Bootable Rescue Disk for the first time I think I was on the right path but used it incorrectly. I went to Recovery and made the mistake of recovering everything back to my last full backup and inclusive incremental backups and it took about 8 hours. As a result I lost all work done for approximately 3 days in which time I had not done an incremental backup. I have an external harddrive dedicated to nothing but backups and the operating system is XP Pro. Question #1 From the Bootable Rescue Disk TIv9 would it have been correct to go to the restore files area only area and JUST restore everything in the WINDOWS folder to fix the problem of the missing or corrupt Windows\System32\Config\System? If so it would probably have restored the operating system very quickly. Question #2 From within the Bootable Rescue Disk could I have saved files, to a new folder, I had been working on that had not been saved in previous incremental backups. Question #3 In the Bootable Rescue Disk is the MBR the path to be followed in Recovery in order to recover just the operating system? Question #4 Is there a way in TIv9 to do a restore points as there is in Windows? I know that if you have TI the windows Recovery part can be disabled. I had tried the Recovery point in Windows from Safe Mode but it did not solve my problem. Question #5 I see in TIv10 that it offers some special Outlook features. Is TIv9 not saving some Outlook things? Question #6 BartPE, is this something everyone should have and be using. What does it have to offer over and above what TIv9 already does? Question #7 Can you continue working while doing a full or incremental backup? Sometime I think I understand and then I confuse myself Thanks!
