How to Get Back the Lost Administrative Operating System Password

The first step is to boot the machine using a bootable floppy or CD which has the NTFS drivers. This enables one to proceed to the next step, which is to recover or reset the Administrator password.

Boot the system with NTFS drivers

One may also be able to use bootable floppies or CD’s as long as it supports NTFS file system and one can run the utility which one intends to use in order to recover the administrator password. This step is used only when the system uses the NTFS file system. If your system uses a different file system, then one has to use the drivers for that file system.
