OS present but not present.

    Havent googled yet.....

    Come across a couple of systems running XP (Home and Pro with SP2) which
    start to boot, get to the XP logo, then restart - trying via Safe Mode, VGA
    etc does the same thing.
    So far, you'd expect the OS to be "ok" as such because the OS menu is
    present, and it is showing the XP logo . Driver issue maybe...... ? No... ?
    Try a Windows Repair from the OS cd anyway, to find that the CD dosent
    actually acknowledge an OS being present and wants to do a complete new
    install. Viewing the drive contents via a self booting disk, the drive is
    readable with all files present etc.

    Any ideas what causes this ??

    /start Mode "Google"

    TIA :)

    Found references to this sort of problem and a missing/corrupt hal.dll - so
    I checked for the file on the system in question... found the issue -
    Nothing in the Windows dir except Uninstall information :-/
    Weird.... ghost and install time :)

    When a system auto-restarts at startup often its blue-screening with the
    auto-restart option checked in system options. Bit of a pain in the
    arse because you usually cant make out what the blue screen is, it
    happens so quickly.

    Get into Recovery console from your windows XP boot CD and do a Chkdsk
    c: (or whatever drive it is), that will sort out the problem 30-40% of
    the time perhaps.

    Failing that a Repair install, but you must have the exact version disk
    your trying to repair (ie Home/Pro), failing that (and it does fail
    sometimes) full reinstall.

    The windows logo doesn't mean much in terms of how far the OS has
    loaded, your system can be almost completely hosed and you would still
    get the windows logo.

  4. I'd say your filesystem/ partitioning is just completely shot.
    Check the HD doesn't have bad sectors..

    Note above: "a couple of systems". I don't think they share the same HDD.
