Preparing for InstallationWindows NT comes with three disks that contain a simplified version of Windows NT, enough to boot a PC. If the hard drive does not contain an OS, the installation begins by booting from these three disks.After Windows NT is loaded from these three disks, it can access the CD-ROM drive, and installation continues from the CD.The program on the CD executed at that point is Winnt.exe, a 16-bit program.A faster version of Winnt.exe on the CD named Winnt32.exe, a 32-bit program, can be used instead of Winnt.exe in cartain situations.Winnt32.exe can be run only after Windows Nt has already been installed for the first time; it is used to upgrade from an older NT version to a newer version or to reinstall a corrupted version. It must be executed from within Windows NT.The three startup disks can later be used to boot the PC if files on the hard drive become corrupted. You can also create a new set of bootable disks.The Windows NT installation files are stored in the \i386 directory on the CD-ROM drive. If hard drive space is plentiful, you can copy the contents of the \i386 directory and its subdirectories to the hard drive and install from there, which is faster because access to the hard drive is faster than access to the CD-ROM drive.If the computer is connected to a network, the contents of the \i386 directory can be copied to a network server, and the Winnt.exe program can be executed from the server to install Windows NT on the PC, if certain conditions exist. To perform an upgrade to Windows NT, boot the OS and axecute the Winnt.exe program on the Windows NT CD.
