Giving “Missing operating system Error on Boot”

Missing operating system Error on Boot

Checked for HDD in BIOS setting it does not show HDD….

For this type of failure- suspected chances of the cause are as follows:

40% cause is due to software corrupt.

30% Hard Disk itself BAD.

20% cause is SATA / Power Cables

& rest is with Motherboard.

For the further diagnosis I have opened the computer……

I have removed HDD for testing whether it works or not (Here I have kept suspected area .i.e. Software related to the last option because customer having some important DATA)…

Removed HDD from casing and connected to another computer via USB Casing. it gets detected and showing the data directory tree intact…….so First doubt I have cleared about Bad HDD. HDD is detecting and working Ok.

Now second suspected area is Cable ….

There are two SATA Connectors one is for HDD and other is For DVD. So I have removed sata cables from the motherboard for inspection.

Here I found HDD SATA cable is ok but Connector was broken on the Motherboard….

I don’t want to take risk for repairing motherboard because in this covid lockdown period in our country and availability and arranging of this part is also a question.

So I have convinced the situation to the customer by giving one option that we have to eliminate DVD Drive and use that port for the HDD till the situation is normal again and further we arrange the part accordingly.

And customer agrees………..As per discussion I have made changes (Connected HDD SATA cable on DVD Drive Port) on the motherboard and powered on the system and now HDD is detected and operating system is ready to use.

      I have a similar problem, but mine involves an external hard drive. All my laptops even with the latest software do not detect my external hard drive. I can feel the disk spinning as soon as I plug it in USB port and it will show a light that it is connected, but it never get detected and I cannot open or retrieve a file or folder. My worry is that I have an E-book for smart phones saved in it.
      Can you suggest something please.

        It is possible that there is no actual drive letter assigned to your external drive or it has one that already is used by an internal device. When this happens the hdd drive will be invisible to the Explorer window. You can check and change this in Windows Configuration and its tools. But I can't give you the exact English toolnames because I'm Dutch and my Windows is too. Or just use any free Partition Manager (careful not the delete anything!) to see if it detects your hdd device. Good luck!

        There are variety of types of the external HDD available in the market so the solutions may not applicable to all the types.
        Try to use USB "Y" cable because some External drives need more power to reach the peak latency.or if you are technical guy just open the external drive unit remove the HDD and connect it in the PC Motherboard Using appropriate DATA and power connector and retrieve the data.....But if you are not technical guy do not try to open the HDD external casing or you will the destroy the HDD beyond chances of DATA can try it buying a new external HDD Casing also.

    Good decision! And the customer probably also can still use other boot options like using an USB memory stick with a prepared Windows image on it. Or use an external hdd with an boot image on it. Although those options if they work of course are much slower.

      Thanks! Albert
      This process is OK if you are technical guy and aware of the technology. But personally i feel that if you want to use any External HDD/USB just use it as a backup device and do not keep it attached to the device while not in use.Once you transferred your data just disconnect it from the device.
      Because you are attaching it on external USB Port which doesn't having any lock system which can hold the connector cable tightly /firmly .If device get the jerk cable get loose from the USB Port and you will loss all your work.

    I would suggest you connect your HDD to a sata or Pata port (depending on the HDD interface) to a computer to see if the drive is visible by the bios and the windows. AS I have found that external drive case's can fail.

      Thanks! for the Comment

      Process for Data recover commented by you is right. I have already mentioned my personal view to Albert about Using External drive for the purpose.
