This article describes how to swap your current primary boot hard disk (usually drive C) with a different hard disk and retain your current files and system configuration in the process. This primarily involves installing Windows 95/98 on a new hard disk and ensuring proper identification of the new hardware. This process uses Microsoft Backup to back up and restore files and configuration and registry settings.
Note that the method described in this article cannot be used to copy Windows 95/98 installations to multiple computers. Microsoft only supports the use of the standard Setup procedure as described in the Windows 95/98 product documentation for each computer on which Windows 95/98 is installed.
WARNING: Before proceeding, fully review this article. Because of the many steps involved, use this article only if you feel you have sufficient experience to correctly perform all required steps. If not, the safest approach is to back up your data files, run Windows 95/98 Setup on your new hard disk, reinstall all of your programs from original program CD-ROMs or disks, and then restore your data from backup.
If after reviewing this article you choose to proceed, carefully execute each set of steps as written.
IMPORTANT: This article applies only to the replacement of the hard disk. Do not use this article if you are making other hardware changes. Improper use of this article can result in the loss of all data on your hard disk. Microsoft is responsible only for the information pertaining to Microsoft software installation detailed in this article. For correct procedures and safeguards when handling hardware, refer to the documentation included with your hardware or contact your hardware vendor. Improper handling of hardware can be dangerous and can cause permanent damage to your computer. If you are unsure how to handle hardware, we recommend that you have a factory-qualified hardware technician perform the upgrade.
Disks and Information Required
Choosing a Backup MethodThe procedures outlined in this article require Microsoft Backup, which is supplied with Windows 95/98. If Backup is not currently installed, see the instructions in the "Installing Windows 95/98 on Your New Hard Disk" section of this article.
Each of the following methods uses different hardware. Use the appropriate method:
Method 1: Using Backup with a Tape DriveThis method requires compatible tape drive hardware. For additional information about tape drives that are compatible with Microsoft Backup, click the article numbers below to view the articles in the Microsoft Knowledge Base:

242864WARNING: When you are using Backup as described below, manually selecting drive C instead of using the Full System Backup set does not back up vital parts of your system (such as registry files). If you do not see the following message after Step 5 in the following procedure, you have not performed these steps correctly and you will need to restart the process:

Before starting Backup, perform the following steps:
Microsoft Backup is now making a copy of the settings in your system registry. This will take a few minutes.
Method 2: Using Backup with Your New Hard DiskWARNING: Do not use method 2 if your computer requires disk overlay software to access your hard disks.
Before starting Backup, calculate the estimated minimum disk space required on your new hard disk as follows:
For example, if your current hard disk has 400 MB total used space, the estimated minimum disk space required on the new disk would be:
(total space in use on current hard disk) + ((total space in use on current hard disk) * 0.66)
The result equals the approximate size of a full system backup. The ratio (in this case, 3:2) is only an estimate and varies from drive to drive depending on the file types being backed up.
400 MB + (400 MB * 0.66) = 664 MB
The new hard disk must have at least the estimated minimum disk space available.
If your current hard disk is compressed, substitute 1.0 for 0.66 in your calculation. In this situation, the required space in the example above is 800 MB.
If you have inadequate storage space on your new hard disk and you cannot remove any files or data, use method 1 instead. Note that the Temporary Internet Files folder may contain files that can be safely removed.
Install the New Hard Disk as a Secondary Drive:
Before running Backup, you need to install and configure your new hard disk. For information about how to install and configure your hardware, refer to the documentation that came with your hard disk or contact your hardware manufacturer.
After your new hard disk is configured, follow these steps:
Preparing Your New Hard Disk Using Fdisk and FormatWARNING: If your computer requires disk overlay software to access your hard disks, apply Fdisk and Format as described below only if advised to do so in the documentation provided by your overlay software manufacturer. The installation of the overlay software may provide functionality equal to that described in this section.
Most new hard disks have not been partitioned or formatted. If your new hard disk requires this basic configuration, use the following tools to prepare it for file installation.
Partition Your New Hard Disk Using Fdisk:
WARNING: Before proceeding, verify that the disk you are about to partition is the new hard disk and contains no important data. If you are unsure, stop immediately.
For information about using Fdisk to partition your hard disk, see the "Repartitioning Your Hard Disk" section in following article in the Microsoft Knowledge Base:

Using Format to Prepare the File System:
After the new drive is partitioned, run the Format tool as follows:
Installing Windows 95/98 on Your New Hard DiskFor Windows Setup information, refer to the "Setting Up Windows 95/98" section of the booklet included with your Windows 95/98 CD-ROM or disks. If Windows 95/98 came preinstalled on your computer, refer to your manufacturer-supplied documentation.
When you set up Windows 95/98, verify that the folder in which you are installing Windows 95/98 has the same name as the original folder (typically, C:\Windows).
NOTE: The Setup procedure requires access to your original Windows 95/98 disks or CD-ROM or to the server-based-Setup shared installation of Windows 95/98. To install from a CD-ROM, the real-mode CD-ROM drivers must be loaded in the Autoexec.bat and Config.sys files. Refer to the documentation included with your CD-ROM drive for driver installation instructions.
When you are prompted during Setup, choose a typical installation.
After Windows 95/98 Setup is finished, install the Microsoft Backup program as follows:
Restoring Files and Folders from BackupBefore you restore your files and folders, verify that the following options are enabled on the Restore tab in Backup:
Backup restores the registry entries when the program is finished. The following text may be displayed in a dialog box near the end of the process:
Microsoft Backup is now restoring the settings in your system registry. This may take a few minutes. Do not shut down your computer until the registry is fully restored, or your computer will not work properly.
Restarting Windows 95/98 on Your New Hard DiskWhen Backup finishes restoring your files, you need to close all programs and restart your computer. After you restart your computer, you may receive the following message:
If you receive this error message, use the following steps:
Invalid System Disk. Replace the disk, and then press any key
Deleting the Backup File on the Hard Disk (Method 2 Only)When you verify that all files and programs are properly restored to their previous functionality, you can delete the file created by Backup in the root folder. The file name is the name given in step 7 of the backup instructions in method 1 and is displayed with a .qic extension if Windows Explorer is set to show file extensions.
Additional InformationUsing the procedures in this article to back up and restore files to your new hard disk protects your current configuration and long file names. If you choose to back up your previous operating system during your initial upgrade to Windows 95/98, you retain the ability to uninstall Windows 95/98.
The procedures listed in this article for swapping a hard disk containing Windows 95/98 on drive C with a new hard disk are the only procedures supported by Microsoft. Other methods may cause system instability or data loss.
