    Hello all,

    Win XP pro does not start. After the "loading XP window with the progress bar", I get a blue screen with the following error:

    _________________________________________________________________
    c0000218 (Registry File Failure)
    The registry cannot load the hive (file):
    \Systemroot/system32/config/software
    or its log or alternate.
    It is corrupt, absent or not writable.
    _________________________________________________________________
    It shows the same error screen even for safe mode and last known good configuration.


    Lately, the BSOD had started appearing quite frequently and everytime a different error code used to appear.
    The last time I was shutting down my computer the BSOD had appeared and so I switched it off from the main power switch. This probably corrupted some registry settings.(http://support.microsoft.com/?kbid=822705)

    Any help shall be greatly appreciated.

    I had made a set of 6 XP setup disks a few months ago. Are these setup disks specific to my system or common for all XP systems? Can these be used to correct the registry?

    a repair is done by booting from the xp cd and choosing install
    then continuing with install until windows finds the previous installation and offers the repair

    The lsass.exe system error -An invalid parameter was passed to a service or function.
    pops up during "installling windows" step. On pressing Ok the pc reboots.
    What do I do? Format and fresh install?

    It is a small l.

    When XP was fine, I regularly scanned my computer with online scans, avg free with latest def was installed, XP firewall was enabled.

    Any idea how can I access C drive using recovery console?It asks for administrator password (which is actually blank).

    leave blank and press enter
    in the recovery console type help and it will give a list of available commands
    i am not sure if it is a virus but it is virtually all that come up on searches and you need to be into windows to do anything with the search results
    i was looking for it appearing in an install or a repair,i did find a link to ms but it has been removed and the only thing close said to install the latest sp,which is not much use in the circumstances and i think it is because it is patched to stop the virus after sp1
    that's why i suggested the format might be the quickest option

    >>Leave blank and press enter
    This used to work when "Registry error" used to be displayed.
    But after I Performed part 1 , 2 and 3 mentioned at http://support.microsoft.com/?kbid=307545, the lsass.exe error started comming.
    Now even after pressing enter in Recovery console, it says invalid password.

    Anyway I will format C partition.
