Hard disk not detected during Windows 7 installation.

I`m saying if the install disc doesn`t see the drive, it may be damaged.

How old is it ?

Approx. 6 Year old. Is there no any method to load driver externally mean slipstreaming driver with Windows installation disc. If HDD goes dead then why it shows in bios .

Try selecting "load driver" in the lower left corner. See attached. Do not choose whats in the red box. You want "Load Driver" located in the lower left.

Have you tried this? When installing an OS and you get to this and your HDD is not in the list, this is what your next step should be. Give it a shot, it won't hurt anything.

Indeed enter and exit twice to close diskpart.

I would also use format to format the drive in the installer,

Might seem like a waste of time but what you would be doing is cleaning the drive with multiple passes which will not hurt anything at all
It's the for sure way I've found to Not have a 100mb system reserved partition created which I never want installed.

I would guess it's the bios setup that is stopping or as said possibly the drive it's self is weird
Post some boot and security bios screen shots
Installing a driver shouldn't be needed as you state cdm see's it and you can format it

Secure boot disabled
CSM enabled
Fast startup disables
os type other or windows uefi mode

Just make sure nothing says uefi only.

Don' t able to understand your suggestion. How I enabled csm and os type other or windows uefi mode

No drive listed during installation time. So no any option to load driver.

I'm sorry. I should be more clear. If the driver is not loaded you will get the above screen with no hard drive showing up. You must then load the driver by clicking "Load Driver". You can get the driver from the manufacture if you don't have it and put it on a usb and navigate to it. I personally have not had to do this but this is what I learned when studying computers. That is why the "load driver" option is there.

So from where I can download the driver.
Mainboard manufacture and model : Mercury PIG31U
and HDD manufacture is : Segate ST3250310AS
For which one I need to download the driver.

For now follow ThrashZone's directions. He has been around a lot longer than me. Then if you are still stuck, we can proceed with the driver issue. Normally you would not need to do the driver step. Like I said, I have never had to do it. In the mean time, if you could post your PC manufacture and complete model number, I will go ahead and find the driver just in case.
