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.

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: 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:

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.
