  1. I just disconnected and reconnected the HD from one of my computers and now
    when I start it up it says no operating system found. It was windows 98 and
    I don't have the 98 disk anymore.

    "No Operating System Found" is an error from your BIOS. This tells us your hard drive is no longer bootable for whatever reason. Just so you know - this isn't a Windows problem - this is a drive, file system or boot record problem.

    Make sure you remove any floppy disks that may be inserted into your floppy drive. Ensure you've connected the drive properly and master & slave settings are properly set. Double check and triple check both the power and data cables connected to your drive at both ends. Lastly, enter the CMOS/BIOS setup and ensure the boot device order is correct.
