Hi, I have a dual boot laptop with WinXP and win2000. I recently changed my HD from a 20GB to a 40GB. Now the win2000 does not start anymore. XP works fine, but Win2000 stops when booting with this message: "file is corrupt or missing: WINNT/appPatch/drvmain.sdb" When i check my backups - the drvmain.sdb file is not part of the win2000 system either. Anyone have an idea how to fix this ? The boot.ini is exactly the same. Thanks, Joel
