  1. Due to a virus intrution I can only access one of the two hard drives on my system. I have tried repairing and other things but no luck. Does anyone have a solution for this?

    If you have Windows XP Setup CD you can boot from it and use the repair option to repair your windows installation.

    I have tried that option and have no luck. What ever has infected my comp is preventing the setup disk from completing the repairs. Do you have any other options?

    It its not repairing (and i assuming you can't boot into safe mode as well); there are not very many options left. Probably the partition is damaged as well.

    However, if you do not have any personal data on that partition you can simply reinstall windows and get on with it.

    I have tried safemode aswell. This, what ever it is, is one bad bug. Thank you for your reply. I do have another drive on this computer and I can access the other drive and go in through the back door. I am not sure what I can do once I am in. Any suggestions as to what I might be able to try using that avenue?

    Where is the snapshot data? Sorry I feel like I'm missing something...I went forward and did the steps after #7 and I got stuck on #10....I've been at this thing for about 2+ hours, so it's totally possible that my brain is fried lol.
    But yeah, I get along fine, but once I try to to the copy
    _registry_machine_system....
    I am told that the command is not recognized and I need to type HELP for a list of supported commands :(
