If you do not update your Windows 95 Startup disk (also known as theEmergency Boot Disk) either when you install Microsoft Plus! for Windows95, or when you run DriveSpace 3, you may not be able to start yourcomputer with the Startup disk.
The Startup disk has not been updated for DriveSpace 3. Therefore,DriveSpace 3 compressed volume files (CVFs) cannot be mounted or repaired.
If Windows 95 starts normally, you can create a new Startup disk withupdated files by following these steps:
In Control Panel, double-click the Add/Remove Programs icon.
On the Startup Disk tab, click the Create Disk button.
