    Hmm, it's kinda muddled but are you saying you made the old hard drive with
    Win2K on it the primary and booted from it with the WinXP hard drive as a
    secondary hard drive? If this is the case, the partitions on your XP drive
    have been renamed in the MBR of the XP drive to follow those of the primary
    drive; when you make it a primary drive again and try to boot from it now
    the renamed drive letter sticks, e.g. at D: or some other letter depending
    on the partition structure of the old hard drive, and it doesn't know where
    the OS is.

    One M$ recommended procedure to reset the drive letters of your XP drive --
    basically wipes the mangled drive letter assignments in the MBR -- and the
    simplest one, is to make a Win98 bootable floppy with FDISK on it. Boot
    from that floppy and enter FDISK /MBR.

    A repair install will fix the OS without losing your data, assuming you
    have a proper installation CD, and not just a recovery CD. Google for
    'Windows XP repair install' for details of how to.

    When you added the second disk, you changed the disk and/or partition
    order. Now your boot.ini file is pointing to the wrong disk and/or
    partition and doesn't find the operating system. Use a bootable floppy
    with an editor and correct the boot.ini entry so that it points to the
    partition containing the OS. If you don't know what your disk and
    partition entries are, or the boot.ini syntax, then you need to
    research this and figure it out. You may still have issues if the
    partition letter assignments have changed, but at least the OS will
    boot.

    Alternatively, you can simply do another installation of Win XP on
    some partition without re-formatting the hard disk. Your data files
    should remain intact after doing this, as long as you don't format
    anything.

    Try 'testdisk' utility and use it's file system analyzation
    capabilities to rebuild your partition table.

    Like someone else suggested, try booting from the WinXP CD and run the
    repair procedure - sorry I don't recall details.
