SunPCi User's Guide

Creating Windows NT Repair Disks

The boot floppies that come with the Windows NT Workstation package do not contain the SunPCi drivers. If you try to use these repair disks to recover from a Windows NT, the SunPCi drivers will not be installed and the software will not work correctly.

If you want to create a repair disk for your SunPCi installation of Windows NT, perform the following procedure:

  1. From the Start Menu, choose Shut Down, and then choose Restart the Computer.

  2. Click OK.

    Windows NT shuts down and restarts.

  3. At the OS Loader screen, use the down arrow key to select Previous Operating System on C:. Press Return.

    SunPCi then boots into DOS. When it has finished booting, the DOS prompt (C:\>) is displayed.

  4. Back up the following files to another area on your workstation's hard disk or to a floppy. These files are needed in order to initialize the MS-DOS environment.

    C:\winnt\system32\Autoexec.nt C:\winnt\system32\Config.nt

  5. Copy the following files to a floppy disk. If Windows NT Workstation 4.0 does not start up, you will need this floppy in order to boot Windows NT.

    C:\Ntldr C:\Boot.ini C:\Ntdetect.com C:\bootsect.dos C:\Hal.dll

    You might want to make more than one copy of this floppy, in case one copy is damaged or lost.

  6. Copy these registry files to a directory on your workstation's hard disk (such as $HOME/temp). You will need these files to restore the Windows NT Registry.

    C:\System32\config\Sam C:\System32\config\Sam.log C:\System32\config\Sam.sav C:\System32\config\Security C:\System32\config\Security.log C:\System32\config\Security.sav C:\System32\config\Software C:\System32\config\Software.log C:\System32\config\Software.sav C:\System32\config\System C:\System32\config\System.alt C:\System32\config\System.sav C:\System32\config\System.log C:\System32\config\Default C:\System32\config\Default.log C:\System32\config\Default.sav C:\System32\config\Userdiff C:\System32\config\Userdiff.log

    Note –

    You may not have .sav files in your directory. This is normal. However, if you do have .sav files, it is a good idea to back them up.

  7. Copy these files to floppy to restore the default user profile:

    C:\winnt\profiles\Default User\Ntuser.dat C:\winnt\profiles\Default User\NTuserdat.log

    Note –

    In DOS, the directory will appear as C:\winnt\profiles\Defaul~1\.
