Windows 7: Hard drive problem with partition. Even after a new replacement drive.

Hard drive problem with partition. Even after a new replacement drive.

After sending in my new 750 GB Western Digital Black Edition hard drive due to my partitions getting completely screwed multiple times. I received a brand new replacement 1 TB Western Digital Black Edition hard drive yesterday. Everything was working fine until I turned on my desktop on today and received the message "operating system not found". This is the same problem I got with my older hard drive. I tried everything, including creating a new partition using the command prompt on my old hard drive and I still had the same problem. I haven't tried anything yet with my new hard drive and I'm wondering what is causing my hard drives to do this? Any ideas of what could be causing this and fixes would be immensely appreciated. Thank you for your time.

Note:
-Not posting this from my desktop.
-Both drives are OEM and I do not have any discs with to run a diagnostics or repairs.
-I can not start up Windows in anyway.
-I still have my Windows 7 64 bit disc.
-My computer does not recognize my hard drive due to the partition being corrupted.

Seeing how I can not even access my operating system, running a disk check through that method is impossible through me. It seems like I can only use a command prompt to make any changes.

You do not say whether you were ever able to install an OS on the old or replacement drive. I will have to assume no.

On the hardware side of the equation, you normally get the "operating system not found" message on black screen during the boot process if
  1. there is no operating system installed on the hard drive
  2. no partition is marked as Primary/System
  3. no hard drive is connected to the computer
You can test #3 by simply unplugging the drive and booting. Is that the same message you are getting?

In your BIOS you should check to see if your drive is recognized and configured correctly.
If an OS is installed, then under the "Configure SATA as" settings you need to be sure that if you installed W7 under ACHI (or RAID) that SATA is configured that way.

If you are getting the message because of #3 above then the BIOS cannot "see" the drive. That can happen if
  • There is no power to the drive/drive does not turn on
  • SATA cable not connected properly at the drive or on the board
  • Bad SATA cable
  • Defective SATA socket (try another socket)
  • Defective motherboard - SATA controller
  • Power Supply issues
You want to eliminate hardware issues before you start working on the OS side. But if you can't get as far as starting the OS boot process then it is hard to see how this can be strictly an OS issue.

To clear up some confusion. Yes, I did have Windows 7 installed and fully operational on my new hard drive. Everything was working as normal. I turned my computer off the same night I installed the OS and when I booted back up the next day, I received the "operating system not found" message. I have a good feeling it is a partition problem because I ran a system start up repair with my OS disc and in the details it stated that there was a corrupt partition(s). This same exact problem happened with my previous drive which leads me to believe that it is not a drive issue. Something is courrupting/deleting my partitions.

Note: When trying to run a full OS install, my computer does not recognize my drive. There is no drive listed. But my BIOS does recognize my drive.

Thank you for taking the time to read and assess my issue.

So how did you get W7 installed if when you tried to install it the installation did not recognize your drive?

Did you clone the OS from the old drive to the new one?

When my partitions got corrupted on my old drive, I used command prompt to create new ones. Then I was able to re-install Windows 7. Even though I created new partitions and re-installed my OS, they became corrupted again.

My new drive came in working perfectly. Its when I already had installed my OS on my new drive, I turned off my computer and turned it back on, my partitions were corrupted and I could no longer access my OS or drive itself.

OK, I'm guessing now.
If you are sure you are not dealing with a hardware issue, then you may have a corrupted Master Boot Record (MBR). I don't know how that would happen on a brand new drive without doing a clone copy.

See the following articles to see how to fix the MBR:

How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

Run fixmbr from within Win 7

See if that helps.

I have an old 320GB hard drive that's dying and slowing my computer down. The OS is on a 20GB partition. I want to copy that partition onto an empty, 110GB hard drive. Will the data copied be corrupted? am I better off re-installing windows? How can I do this?
