Hi shannoboy, The operating system seems to be corrupted. Please contact a local technician who may help you in reinstalling the operating system.

Hi,

You will need to boot with the disk, and repair windows.

bootmgr 6 Fix: Missing Operating System Not Found error in Windows

From above, click Command prompt,

Now enter the following commands one after the other and hit Enter after each:

bootrec.exe /fixmbr

bootrec.exe /fixboot

bootrec.exe /rebuildbcd

Reboot your Windows system.

This should hopefully and have made your problem go away !

But how can I use repair method in OS if my hard dik wasnt detected?

You can run those commands by booting to Windows installation media - USB flash drive or USB external DVD is fine - instead of Install Now, select Repair Your Computer.

But can I do that even if the HDD is not detected in the BIOS? I ran diagnostic test but HDD doesnt appeared. M y hdd ddnt spin / vibrate when boot up

Hi, Hard disk failed totally. You will need replace the hard disk to new one. If its under warranty, call Dell technical support otherwise Contact Dell local retailer

I will not buy new HDD sir, Its totally working I tried to insert it to other laptop and it works... and also I tried other HDD to insert to my dell netbook but its also failed to detect.

Running the commands will fail if no Windows installation is found (no disks found).

If your disk is not detected in the BIOS, then one of two things is the problem: the disk or the computer.

If the disk is bad, it may respond only to certain commands or connections, working on one computer but not the other.

If the disk is good (seems to be from your "test") and it is still not detected, your cable (if there is a cable) may be bad (or disconnected at either end), the drive port may be disabled in the BIOS, or the onboard controller (motherboard) is malfunctioning. Make sure the drive port is enabled and that the disk is securely connected, and try clearing the CMOS using jumpers or battery to clear the settings.

there was no cable on HDD

shannoboy · Answer

Kindly check thie image, this is the settings on my BIOS and it's by default.

theflash1932 · Answer

There isn't always a cable, but it looks like there may be some type of an interposer/adapter. If you have reseated both the connector and the drive, then you have done all you can do for checking the cable (connection).

If known-working drives don't work in here, then it could be that interposer/adapter, but it is more likely the controller on the motherboard has gone bad.

Try removing the battery or clearing the CMOS using jumpers (if this system has jumpers for so doing).
