TSGL: Hard disk access

[Anthony Shearman]

PC with 896Mb RAM
Windows Xp Professional with SP2 and updates

My HDD is not available. The PC identifies it properly in the BIOS but when 
I turn it on it comes back and says there is no Operating System.

I have tried formatting using the Windows CD and it goes through the 
formalities and installs Windows but when I re-start, I get the same OS 
unavailable message.

I tried to format from DOS but when I go through FDISK, it comes back and 
says No hard disk present.

The HDD is readable in another PC so that is not the problem.

Does this mean that my Motherboard needs replacing or is it a problem with 
the cables.

Any solutions will be very welcome.
