    Repairing system with damaged registry

    I have an unbootable Win8 system. I know that the System and Software hives are corrupt. I started the system with the Win8 install disc and tried to do a repair. I get to the point where the screen indicates, "Repairing disk errors. This may take over an hour to complete." However, the system continually reboots after the above message appears and repeats the process indefinitely. Thanks for any suggestions.

    First boot into the BIOS, make sure the drive is listed and being recognized.

    If the drive is listed, boot from the install disc again.

    Click on “Repair your computer”
    Click on “Troubleshoot”
    Click on “Command Prompt”
    Click on “Advanced Options”

    From the command prompt type: chkdsk C: /R

    Thanks, ectech. I'm afraid that running chkdsk with the repair switch will not repair damaged registry hives. The utility basically attempts to repair broken file system links. It certainly doesn't hurt to run it, though it can't fix the problem that I posted. The SYSTEM and SOFTWARE hive are corrupt. I extracted them from a disk image, and they will not load in registry viewers or in regedit. I'm looking for some repair tool that can recovery the registry so as to load Win 8.

    Correct, chkdsk will find and attempt to repair damaged sectors which might contain data (including the registry hives). If the hard drive sectors have become partially readable then using chkdsk /r is a good starting point.

    The utility basically attempts to repair broken file system links.

    Yes, the utility will attempt to repair the file system using chkdsk /f not /r.

    Did you run chkdsk /r?
