Hi, switched on a PC this morning to a SYSTEMced error.. I've found the MS Windows 2000 Registry Repair Utility and downloaded it. I actually already had some Win 2k bootdisks, 4 disks actually rather than the 6 mentioned in the Repair Utility. I ran the setup file on the Repair Utility but it wouldn't run as I was trying to install on the 4th disk and it needed the 6th.. So I went back to the MS site and downloaded the recommended "Windows XP Professional Utility: Setup Disks for Floppy Boot Install" to create the 6 setup disks. My concern here is that my installation is Win 2K Pro not Win XP and I'm concerned I might do some damage here by trying to 1) boot with XP boot disks 2) the repair utility might think it is repairing a WinXP installation rather than Win 2K Pro. Can anyone offer any guidance as to whether I should be concerned about this? Thanks as always for the help.. Andrew

I tried using the XP Boot disks to see what happened.. I got to boot disk 6 and then got the error: STOP C0000221 UNKNOWN HARD ERROR \systemroot\system32\ntdll.dll which isn't thrilling. I wonder if this is because these are XP boot disks and I have 2k Pro? Any advice very much appreciated. Thanks Andrew

Hi, I seem to have resolved this. I used the procedure described in http://jayroos.com/tech/tips.php?ID=8 to get into windows 2K with the repair menu/console. Renamed the bad system hives and then restored the registry with a piece of software I have called Configsafe. It then booted fine..
