Upgrading Windows 95 to Windows 98

There are two methods for upgrading from Windows 95 to Windows 98. The method you choose depends on whether you want to retain the existing configuration settings on your computer.

Keeping Current Configuration Settings

With this method, Windows 98 is installed in the same directory as Windows 95. Windows 98 Setup will use the existing configuration information to set installation defaults and to set other configuration options. Windows 98 Setup migrates all Windows 95 folders and programs to Windows 98, so they appear on the Windows 98 Start menu. Windows 98 automatically migrates all the shortcuts you had under Windows 95.

Start Windows 95.
Close all programs, including any anti-virus programs.
Insert the Windows 98 compact disc into your CD-ROM drive.
On the Start menu, click Run.
In the Open box, enter the location of the Windows 98 disc.
Type d:\setup. Click OK.
The Windows 98 Setup Wizard starts. Follow the on-screen instructions
Changing Current Configuration Settings
Before you begin, you should be prepared to provide the following information:

Name of the installation directory (for example, c:\Win98).
Network information, such as your computer name, workgroup, and computer description (if your computer is on a network).
When starting Setup from MS-DOS using either a network server or local CD-ROM drive, the real-mode network or CD-ROM drivers must be loaded. If the real-mode network drivers are running when you start Windows 98 Setup, the appropriate network client is installed automatically. Setup detects existing network components, installs the appropriate supporting software automatically, and adds the necessary network settings in the registry.
Start your computer up and press F8 when the message, Starting Windows 95 appears. Then select Command Prompt Only. Or From Windows 95, click on Start, and click Shut Down. Then select Restart in MS-DOS mode.
Insert the Windows 98 compact disc into the CD-ROM drive, and make it the active drive.
Type setup
After starting Setup from MS-DOS, Setup initializes and checks your system: It runs real-mode ScanDisk to check the hard disk for errors. Unlike the protected-mode version of ScanDisk, the real-mode counterpart cannot fix errors in long file names. ScanDisk does not perform a surface scan; therefore, the disk is not checked for physical errors.
The setup wizard will run complete the following five steps of Windows 98 Set up
Preparing to run Windows 98 Setup.
Collecting information about your computer.
Copying files to your computer.
Restarting your computer.
Setting up hardware and finalizing settings.
Upgrading Windows NT Workstation 4.0 to Windows 2000

To upgrade Windows 95, Windows 98, or Windows NT 4.0

You must uncompress any DriveSpace or DoubleSpace volumes before upgrading to Windows 2000

Start your current operating system, and then insert the Win 2000 CD.
If Windows automatically detects the CD and asks if you would like to upgrade your computer to Win 2000, click Yes. Otherwise, click Run. At the prompt, type d:\i386\winnt32.exe
Follow the instructions that appear

Replacing Windows 9x with Windows 2000

For a Clean Install of Win 2000

With your computer turned off, insert the Windows 2000 Setup startup Disk 1 into your floppy disk drive.
Start your computer, Setup starts automatically
Follow the instructions that appear
Dual boot Windows 9x/Windows NT 4.0/2000

Windows 2000 supports multiple booting with MS-DOS, OS/2, Windows 3.x, Windows 95, Windows 98, Windows NT 3.51, and Windows NT 4.0.

If you intend to create a dual-boot system with Windows NT 4.0 and Windows 2000 as the only installed operating systems, you must ensure that you have installed Service Pack 4 for Windows NT 4.0. Windows 2000 will automatically upgrade any NTFS partitions it finds on your system to NTFS 5. Windows NT 4.0 requires Service Pack 4 to be able to read and write files on an NTFS 5 volume.

Each operating system should be installed on a separate drive or disk partition.
You should use a FAT file system for dual-boot configurations. Although using NTFS in a dual boot is supported, such a configuration introduces additional complexity into the choice of file systems.
You cannot install both Windows 95 and Windows 98 in a multiple-boot configuration. Windows 98 is intended as an upgrade to Windows 95 and will try to use the same boot file.
To set up a dual-boot configuration between MS-DOS or Windows 95 and Windows 2000, you should install Windows 2000 last. Otherwise, important files needed to start Windows 2000 could be overwritten.
For a dual boot between Windows 98 and Windows 2000, it isn't necessary to install the operating systems in a particular order.
For a dual boot of Windows 2000 with Windows 95 or MS-DOS, the primary partition must be formatted as FAT; for a dual boot with Windows 95 OSR2 or Windows 98, the primary partition must be formatted as FAT or FAT32, not NTFS.
If you're upgrading a dual-boot computer, you can't gain access to NTFS partitions from any operating system other than Windows NT 4.0 with SP4.
If you install Windows 2000 on a computer that dual boots OS/2 and MS-DOS, Windows 2000 Setup configures your system so you can dual boot between Windows 2000 and the operating system (MS-DOS or OS/2) you most recently used before running Windows 2000 Setup.
Don't install Windows 2000 on a compressed drive unless the drive was compressed with the NTFS file system compression utility.
Windows 95 or Windows 98 might reconfigure hardware settings the first time you use them, which can cause problems if you're dual booting with Windows 2000. So run these OS's first before installing 2000.
If you want your programs to run on both operating systems on a dual-boot computer, you need to install them from within each operating system. You can't share programs across operating systems.
Steps for Dual Booting MS-DOS, Win 95/98, 2000

Create partitions for the different Operating Systems, for MS-DOS, 95 the primary partition must be formatted as FAT, and for 95 OSR2 or Win 98, the primary partition must be formatted as FAT or FAT32, not NTFS
Install these operating systems in the following order: MS-DOS, Windows 95 or Windows 98
Install Win 2000
After Set up is complete Win 2000 will present a boot menu with a choice of which installed OS you would like to boot.

Steps for Dual Booting NT 4, Win 2000

Reformat and repartition your hard drive if you have only one partition.
If you are installing Win 2000 with NT 4 on a partition using NTFS, you must have Service Pack 4 for NT 4 which contains updates that enable NT 4 to be able to read and write files on an NTFS 5 volume.
Install Windows NT 4
Install Windows 2000.
