ID: q112019

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1

SUMMARY

This article describes how to change the primary physical disk and controller while maintaining user accounts and desktop settings after you have installed Windows NT.

MORE INFORMATION

This situation may occur when you need larger disk capacity or a more versatile disk controller. For example, if Windows NT is installed on an IDE drive and you want to upgrade to a large SCSI drive without losing user accounts or desktop settings.

NOTE: This procedure is not recommended by Microsoft and therefore is not supported. Microsoft makes no warranty, implied or otherwise, regarding the performance or reliability of this procedure.

To change the primary physical disk and controller while maintaining user account and desktop settings:

1. Create a startup MS-DOS disk and copy FDISK.EXE, FORMAT.COM, and

   SYS.COM to it.

2. Configure both drives.

3. Place a primary FAT partition on the new drive and format it.

4. Use XCOPY to copy Windows NT files and directories from the old drive

   to the new drive.

5. Create a directory called CONFIG off the root directory of the new

   drive and copy %WINNT_ROOT%\SYSTEM32\CONFIG\*.* to it.

6. Remove the %WINNT_ROOT%\SYSTEM32 subdirectory and all of its

   subdirectories on the new drive.

7. Shut down the computer and physically remove or disconnect the old

   drive.

8. Restart the computer, run CMOS, and remove the old drive reference.

9. Insert the startup disk and "SYS" the new drive (A:\sys c:).

10. Remove the startup disk and verify the new drive starts.

11. Reinstall Windows NT over the old installation.

12. After you reinstall Windows NT, start MS-DOS, and change to the CONFIG

   directory you created in step 5.

13. Delete *.EVT and SYSTEM.* files.

14. Copy the remaining files to the %WINNT_ROOT%\SYSTEM32\CONFIG

    directory.

When you restart Windows NT, user accounts and desktop settings should be maintained.
