    I'm working on this HP Pavilion computer which has a 40 gig hd. Well, I
    set it to Primary Master and have the correct jumpers installed. If I
    go into the Bios it doesn't show the hard drive at all. I put the bios
    into auto to detect the drive and it won't do it. I could hit F10, save
    and exit and then it will boot properly. If I shut down and go back in
    to windows, I get operating system not found and the drive doesn't show
    up in bios. I thought it was the battery, changed it and no
    difference. Thought it was the IDE cable. Nope, still does the same
    thing. It seems to loose the settings. Could the hard drive be bad? I
    can't think what else it could be. Other than going into bios and
    hitting F10 and save and exit, the operating system won't come up in
    any other way. When the drive does come up, in windows it reads 40 gig
    correctly. Any ideas??

    What brand is the hard drive? If it is a Western Digital and the only
    drive remove the jumper all together and try it. It would be nice to
    know what you are working with as far components and exactly what you
    have done to it, ie: changed MB, new HD, complete rebuild, etc....

    Hi leon,

    The drive is a Fujitsu 40 gig drive. I tried removing the jumper all
    together on this and the same results. The hard drive is factory
    original in this HP Pavilion. Nothing's been changed at all. Same MB
    too. It' just started loosing settings only in the bios for this hard
    drive. Time,date and all are all fine. Would the drive be suspect?

    You might try changing the HD ribbon cable if you haven't already.
    Double check to make sure the cables are all the way in the sockets.
    Also check to make sure the CMOS reset/clear jumper is in the right
    position and all the way down on the pins. It's always possible the
    drive is bad. How old is the system?

    Hi Leon,
    I'm suspecting the drive is bad. Not sure how old the system is, but
    it's a pentium 3 and looks to be and older style. I changed the ribbon
    cable so I'm guessing the drive is bad and not reading all the time.
    Jumpers are correct as I verified this with the front of the drive for
    primary master. It's weird that it lets me get into the system and all
    works fine when I go into bios and hit f10 to save. However, on reboot
    it gives me "No operating system found".

    I had a similar problem once. My drive would take 15-20 seconds to
    power and spin up. This took too long for the boot process so it would
    report "no HD detected." My solution was to set the "IDE Delay" in the
    BIOS to ~20 seconds. That gave the drive time to power up and made sure
    that it was ready to go when the BIOS was ready to detect it.

    The bad news is the drive failed shortly after that. I would seriously
    look into a replacent drive or at least backing up all critical data.

    I would try to eliminate the power supply before buying a new hard
    drive. If the power supply is "not coming up right" then things that
    shouldn't happen - can.

    Also, the motherboard reads the hard drive's settings on boot up (aka
    boot record). If the motherboard can't read the hard drive then it
    just looks like you've lost the hard drives settings. In actuality,
    the motherboard can't read the drive.

    Drive and also the PSU is effecting system.

    Psu is Oscillating that can cause system wide problem
