I have a stack of recovery CDs from different vendors for the various machines I've had here, but I don't think I have any plain WinXP install disks.
The original 60G drive that's in the machine now doesn't have anything on it anyway. I can reinstall the 500G HD that was in place (and working just fine) when I did the failed upgrade if you think that will help. I took it out to restore the HW to match its as-shipped condition as closely as possible before starting in with the recovery CDs that shipped with the system.
Is the MBR that Data Lifeguard stores on the HD different from whatever would be loaded from the WinXP recovery console? I tried storing the MBR from the Data Lifeguard CD both before and after running the recovery CDs -- on both (60G and 500G) HDs, and neither seemed to make any difference.
My thought was to get something running on the 60G HD with the current RAM, just so that I know specifically what the problem is. When I get the compatible memory upgrade, I'll install it, make sure it works, and then re-install both disks and rebuild the system.
I hope to end up with a working WinXp system with 2G RAM and 2 HDs (500G and 60G).
