I have two related problems that I really need help with:

Problem 1

Somehow my registry in Windows XP Pro SP2 got corrupted - it's giving me the following message:

"Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM"

So I've gone and done the steps as in:

http://support.microsoft.com/default...b;en-us;307545

Except after getting out of the recovery console in Part 1 and rebooting the computer into safe mode, the computer halts with the same message.

I've determined based on chkdsk that the system file was corrupted but by repairing it with chkdsk, it deletes the file and replacing it with the "repair" version of it doesn't fix it. I've even replaced the registry with the files found in the "System Volume Information" directory and it doesn't work either.

I've even tried a repair install by trying rebooting the computer and reinstalling from the CDROM - I'm not given a choice to reinstall Windows. And boot.ini is fine.

Plus since I had Norton Goback 4 installed, it was the first thing I tried though I guess I should have allocated it a lot more space. Anyhow the oldest snapshot it had did not work which was just prior to the problem.

Fixing this problem would be most ideal rather than having to deal with Problem 2.

Problem 2

So I decided to bypass it by getting another Serial ATA hard drive (Seagate Barracuda 7200.7 160G) and connecting it to my NF7-S2.0 motherboard so at least I can backup my data. So I disconnect the old hard drive (Seagate Barracuda 7200.7 80G), installed Windows XP on the new hard drive, reconnected the old hard drive but Windows XP can't seem to fully add the new hard drive.

Windows XP Pro SP2 can find it in that it's added to the Device Manager and the hard drive is located under Disk Management - both drives are viewed as healthy. The old hard drive is shown as active. I even updated the BIOS and Serial ATA BIOS driver (Silicon Image 3112) to the latest versions.

But I still have no way of accessing data off the old hard drive and seeing if I can fix the registry. I'm thinking maybe because Norton Goback 4 is on the old hard drive, it might be messing things up but I'm not tempted to remove it since it's my only way of undoing any changes I make for Problem 1.

I do not wish to lose the data on this drive and I know it's still intact given I can access it via the recovery console.

Can anyone help for either problem?
