When you start your computer, you encounter the following error message:
Load needed DLLs for HAL
This error can be caused if you uninstall Diskeeper for Windows NT 3.5xafter you upgrade Windows NT 3.5x to Windows NT 4.0.
If you install Windows NT on a FAT partition, start in MS-DOS mode and thenreplace the affected files (Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, andNtfs.sys) with the files from the Windows NT CD, or from the service pack,as applicable.

If you installed Windows NT on an NTFS partition, replace the files in oneof the following two ways:
  1. Use the Windows NT 4.0 Emergency Repair Disk (ERD) for this system to repair the system files.

    WARNING: Ensure that you have a good backup of your system before using the ERD. Any services, applications, service packs, and so on, that you added after you created the ERD may be affected by using the ERD.

    - or -
  2. Install Windows NT 4.0 into a separate directory. Start your computer with the temporary version of Windows NT 4.0. Replace the affected files (Ntdll.dll, Ntoskrnl.exe, Fastfat.sys, and Ntfs.sys) in the original installation with the correct version from the Windows NT 4.0 CD or the service pack, if you applied one. After you replace the files and start the computer without incident with the original version of Windows NT 4.0, it is safe to remove the temporary version of Windows NT 4.0.
