SUMMARY

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.

Notes

  • The WARNING designation is placed before procedures in which a mistake in following instructions can cause serious data loss. At these points, verify that you have properly followed the directions.
  • The information in this article applies only when Windows 95/98 is the primary operating system running on a standard MS-DOS partition. Windows 95/98 Backup cannot read files from non-MS-DOS partitions. A new installation of Windows 95/98 overwrites the Windows NT boot sector on computers configured to dual boot Windows NT, disabling the ability to start Windows NT.

Choosing a Backup Method

The 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: Windows 95/98 Backup with a compatible tape backup hardware device attached to your computer. See the instructions in the "Method 1" section below.
  • Method 2: Windows 95/98 Backup using both the original and new hard disks attached to the computer at the same time. See the instructions in the "Method 2" section below.

Method 1: Using Backup with a Tape Drive

This 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:

124730 Tape Backup Units Supported in Windows 95


242864 Tape Backup Units Supported by the Windows 98 Backup Program


WARNING: 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: 

   Microsoft Backup is now making a copy of the settings in your system
   registry. This will take a few minutes.

Before starting Backup, perform the following steps:

  1. Double-click My Computer.
  2. On the View menu, click Folder Options.
  3. On the View tab, click Show all files and then click OK.

  4. Rename the following files:

       File           New name
   ---------------------------
   System.1st     System.1sx
   Suhdlog.dat    Suhdlog.dax
   Setuplog.txt   Setuplog.txx
   Detlog.txt     Detlog.txx
   Bootlog.txt    Bootlog.txx

    NOTE: These files must be renamed, not copied.

After you follow steps 1-3 above, use the following steps to back up your hard disk:

Windows 95

  1. Click Start, point to Programs, point to Accessories, point to System Tools, and then click Backup.
  2. Click OK to close preliminary informational dialog boxes.
  3. On the Backup tab, click Open File Set on the File menu.
  4. Click Full System Backup, click Open, click Next Step, select the destination for the tape drive, and then click Start Backup.NOTE: If Backup does not automatically detect your tape drive, see the following article in the Microsoft Knowledge Base:

    130946 Troubleshooting Windows 95 Backup

  5. : If Backup does not automatically detect your tape drive, see the following article in the Microsoft Knowledge Base: Type a name for the backup set, and then click OK. Record the name for later use.

Windows 98

  1. Click Start, point to Programs, point to Accessories, point to System Tools, and then click Backup.
  2. Click Create a new backup job, and then click OK.
  3. On the Job menu, click New.
  4. Expand My Computer, and then click to select the check box next to each drive.
  5. Click Options, and then click Advanced in the Backup Job Options dialog box.
  6. Click to select the Back up Windows Registry check box, click OK, and then click Start.

When Backup is finished backing up your files, click OK to close the program, and then perform the following steps:

  1. Shut down Windows 95/98 and turn off your computer.
  2. Detach the original hard disk from your computer, and then attach the new hard disk in its place.


NOTE: For hardware setup and configuration information, see the documentation included with your hardware or contact your hardware manufacturer.

  1. When the new hard disk is set up correctly, go to the "Preparing Your New Hard Disk" section below.

Method 2: Using Backup with Your New Hard Disk

WARNING: 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: 

   (total space in use on current hard disk) + ((total space in use on
   current hard disk) * 0.66)

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: 

   400 MB + (400 MB * 0.66) = 664 MB

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.

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:

  1. Follow the instructions in the "Preparing Your New Hard Disk Using FDISK and FORMAT" section below.
  2. When formatting is finished, follow the Backup instructions in the "Method 1" section above. Modify the instructions in step 6 to back up your files to the new hard disk (usually drive D).
  3. When Backup is finished, shut down Windows 95/98, turn off your computer, and remove the original hard disk from the computer, leaving the new disk in place.
  4. Boot with the Windows 95/98 startup disk.
  5. Run Fdisk to set the primary partition on the new disk as the active partition. For information about using Fdisk, see the following section.
  6. Restart your computer to a command prompt.
  7. Proceed to the "Installing Windows 95/98 on Your New Hard Disk" section below.

Preparing Your New Hard Disk Using Fdisk and Format

WARNING: 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.
