Crash & Burn (PC sees no OS)

Hi folks,
Thanks for any help you all can give me.
Let me try and explain whats has happened. I was working with the folks on the Mal-ware board to remove some nastys from my system. I was running Combofix per there instructions and my system crashed and went into memory dump. I allowed the dump to complete and the system to reboot. Upon rebooting I got an error saying "Operating system could not be loaded". I tried a few more times to boot but got the same error message. Out of desperation i put in my XP disk to see what was going on. As I have no ARS disk that option was out. I went in to the set up portion thinking if need be I could just reload XP.
This is what I found. Im running 2 SATA drives. 1 as master and 1 as slave. The set up disk could identify all 3 drive letters (the slave is partitioned in to 2 drive letters) it could even see the 8MB unnamed partition on the master drive. It sees that there is space taken up on the F & G drives but the C drive is blank, as if nothing is on it.

Now my dilemma is this.
I know that there is no way that 70GB of data could have been erased in the time that Combofix was running. So I know the most if not all is still there. I can not just reformat the C drive as there is to much info on there that I cant loss.

So my question is this. Is there a way that i can recover the data, reload windows saving the reg from the old XP install, as I don't want to loss the use of the software that was installed, and set up a raid1 config on the C drive so this wont happen again.

I know I'm asking alot. Adding more hard drives and buying data recovery software is not a problem. Below is a list of hardware I have installed.

Thanks again for any help you can give.

I think he meant ASR (Automated System Recovery) disk?

 

Yes ichase that is what I meant.

Recovering the data on the disk was the easy part of my problem. By just adding a new HD to my system and installing windows on it, then coping or running a data recovery software I know I could recover it. The problem that I face is saving the XP install on the bad disk so that all the software on both of the drive still works.

Is there any way to reintegrate what I pull off the old disk or fixing the XP installation so that the Reg retains the needed info to run the installed software? or is this all just wishful thinking and I should just be happy if I get my files back?

Thanks for any help
