Hard drive not installed after update

I updated my Acer Desktop with windows update and computer will not load W7. The Bios shows hard disk not installed. I ran an Acer e recovery disk in the optical drive and the repair option whist showing will not load showing a fault of '0' drive. The only option showing is the dos command prompt. When I request Bootrec.exe/RebuildBcd nothing happens. When I request DISKPART/LISTDRIVES or DISKPART/LISTDISKS nothing happens. This is presumably because it cannot find the hard drive. I am thinking the windows files have been corrupted.

Any ideas on how to proceed please? On how to make the Bios see the installed c drive?

the fault of drive'0' is a list of signature errors.

The computer 'on' light is one of the across top and down side blue strips permanently illuminated. There is a small blue dot of brighter intensity which flickers when switching on. Presumably this is the hard disk running so why is the Bios not seeing the disk drive?

So the BIOS is seeing the HDD.

Do you have a win 7 DVD? you need to do a startup repair.

How you access the repair options will depend upon whether you have a Windows installation disk or whether your operating system came pre-installed by your PC manufacturer.

Pre-Installed

If no repair options are available your PC manufacturer may have replaced the tools or customised them. Check your Computer Manual before proceeding as another key may be needed to access the Repair/recovery options.

  1. Start your PC

  2. If your PC has one operating system Press and Hold the F8 key as your PC starts. If the Windows Logo appear you will need to start again

  3. If you have a dual boot system a Boot option menu will appear. Highlight the Windows operating system and Press the F8 key

  4. An Advanced Tools menu options screen will now appear

  5. Highlight the repair Your Computer option and Press Enter

  7. Next select your user Name and Enter your Password, then Click OK

  3. A Black screen will appear with the words 'Press any key to boot from CD or DVD', Press Any key to start the booting process

Think I have been misunderstood. I have an Acer recovery disk and can get access to it using a recovery disc in the optical drive. None of the repair options work because it cant find the hard drive, the only one that starts to work is the command prompt but whatever I write nothing seems to work as stated at the beginning. I said the hard drive indicator lights on start up but it is only a single blink so this would probably indicate the hard drive is not powered up. I am toying with the idea of removing the optical drive and swapping over the power lead from the optical drive to the hard disk drive and powering up to see if the hard drive works i.e. thinking its possibly a faulty power supply output lead to the hard drive.

if its a sata drive swap both

Swapped both no change that didn't work.

two options to try

fit another drive and see if the BIOS recognises it.

or

try the old drive connected to another PC.

That will tell you whether its drive or PC that's failed.

It was not a bad connection to the drive. So the problem continues. I have been reading that after an update for reasons unknown the HARD DRIVE CAPACITY can be reduced to zero and hence the reason why the Bios cannot see the hard drive. Has anyone knowledge on how to Restore factory Hard Drive Capacity? This is a problem in the firmware of the HDD.

  Snrub 10:19 11 Mar 2014

Yes I have been reading this site and considering using the recovery tool. I would have to connect the faulty HDD to my good computer by disconnecting power and sata data leads to the optical drive and connecting them to the faulty HDD. Then run the recovery tool selecting the bad hard drive if it shows up on the computer system. I don't want to risk screwing up my good computer so has anyone have experience of this recovery tool Atola Technology HDD Restore Capacity Tool?

  Snrub 13:32 11 Mar 2014

One problem is no version for Windows 7 64 bit which I am running.

Then run the recovery tool selecting the bad hard drive if it shows up on the computer system.

This is obviously not your problem as the drive does not show in BIOS

Have you done what I suggested at 10.14 yesterday? you need to find out if its the drive or motherboard!!!
