Think I'm now half way to an answer./ solution but it doesn't look like this one has an easy fix.
The original SATA HDD was 250GB & working/ booting fine. My ultimate goal was to replace this with 2 spare 750GB SATA HDD's I have.
As I managed to get one of the 750GB formatted & working in an external enclosure, I decided to try clone the working 250GB drive on to the external 750GB HDD using Seagate's Disk Utility.
I then made sure that my Sata operation in BIOS was set to Combination Sata/Pata, before swapping the 250GB for the new cloned 750GB drive.
Bad news is, I still cant seem to get the PC to recognise the other 750GB HDD when its mounted in bay two, but again I have still been able to mount it & format it in the external enclosure.
It looks like this problem might have opened a can of worms though.....How to make a HDD bootable on a Dell Desktop Computerhttp://techrepublic....h...740&start=0 Dell Dimension SATA Drive Windows Installation http://aspadvice.com...#commentmessageInside the Dell Utility Partitionhttp://www.goodells....ility/index.htm
I'm not sure if the info in the links above would apply in this case, but if so one fix may be to try clone the partition containing the Dell Utility files on to the second drive & seeing if it boots.
I'm just not sure if
A. it will work?
B. sure how to go about it?
