My desktop did an update and when it rebooted, it went to repair. Repair and restore both failed. When I looked at the Diagnosis and Repair Details, I see the following for each repaire attempt. System Disk = \Device\Harddisk1 Windows directory = E:\Windows AutoChk Run = 0 Number of Root Causes = 1 Cannot determine Root Cause My windows directory is not on my E: drive (that is an optical drive) it is on my primary drive C: Does anyone know how to reset the windows directory from E: to C: ???

Hi, Thanks for the post! What’s the update you did? Do you mean your system restore failed? Can you enter into Safe Mode? I recommend you check the disk in WinRE: 1. Please insert the Windows 7 DVD and reboot the computer. 2. When we are prompted to press a key to boot from the DVD, please press Enter or the space bar. 3. Click "Next" and click "Repair your computer". 4. Please highlight "Windows 7" and click "Next". 5. In the dialog box titled "System Recovery Options", click "Command Prompt" and type in the following commands. Please press the Enter key after entering the following command. CHKDSK C: /R 6. Click Y and then check if the system is able to check the hard disk.

Thanks for responding. I believe there were 2 updates. A flash up date as well as an AVG antivirus update on one reboot. When the system repair could not find the cause, I was offered the chance to use restore. After many minites of wffoert, I got a message that system restore also failed. No, I cannot get into safe mode. The same repair screen comes up. I read that there is a problem with a recent AVG update. On the AVG site I downloaded an ISO file that runs a repair program in a flavor of Linuix. To no avail. It ran a disk scan but found no problems. I believe the problem is that somehow windows now thinks the "windows" files are all on my DVD drive E. Would such an error reside in the registry? Is there a work around that will allow me to access, search, and edit the registry? Thanks, Brian
