    That isn't looking too good...

    You could have a corrupted boot.ini or ntldr, in that case the computer wont 'see' that you have an OS installed.
    Because you can't even boot into safemode, it'll be very hard to fix if anything is corrupt.

    A way to fix it would be to boot XP CD and try repair, although I'm not sure if it'll work.

    If that isn't sucessful, I'm afraid you'll have to reinstall Windows :(

    BTW: Is there any CD/DVD in the optical drive or floppy in the fdd during boot-up? If there is, remove them.
    In the BIOS make sure you try to set HDD as the first boot device and see if that helps.

    I have noted when the machine comes up with this it does not see the drive running anymore
    try taken it out and load in good machine
    on boot do not let the 2nd machine do a chkdsk
    see if the 2nd machine recognizes the drive
    can you do this or is it to much
    but does sound like your drive is foobar
    when running you should be able to fell it spinning
    PS don't forget the simple stuff like bad power/ide cable connects on the drive or to the board

    Happened to me once and 'fdisk /mbr' did the trick. (fidsk from Windows 98 )
