Windows 95/98

Windows Support Menu


Floppy Boot Disk

The Windows Startup disk, now called the Windows 98 Emergency Startup Disk, has changed significantly for Windows 98. The following functionality has been added:

  • Multi-start menu for booting your computer with or without access to the CD-ROM.
  • Real-mode IDE CD-ROM support
  • Real-mode SCSI CD-ROM support
  • file
  • RAMdrive
  • New extract command (Ext.exe)

The File

The file contains several utilities. It is a compressed file whose contents are expanded during the startup process. The following table lists the contents of this file.

Attrib.exe Add or remove file attributes.
Chkdsk.exe Simpler and smaller disk status tool.
Debug.exe Debug utility. Real-mode emergency text editor.

Note: The files contained in the Startup Disk are copied to the \Windows\Command directory only if the user chooses to create a Windows 98 startup disk during Setup. This happens during the first phase of the Startup Disk creation process. If you create a startup disk from Control Panel (From the Startup Disk property page in Add/Remove Programs) and the startup disk files are not in the \Windows\Command directory, you will prompted for the Windows 98 compact disk. A startup disk will be created but its contents will not be copied locally when you use this method.

Using the Startup Disk

If you have problems with Setup or have trouble starting Windows 98, you can use a Startup Disk to start your computer and run Setup or to gain access to your system files. If you have problems with your hard disk, for example, you can use a Startup Disk to start your computer and troubleshoot your hard disk.

You’re prompted to create a Startup Disk during Setup. If you want to create another Startup Disk after you install Windows 98, you easily can. You can even save a specific startup configuration on a disk. For example, you can save the specific drivers for your computer on a Startup Disk.

The Startup Disk contains generic CD-ROM drivers, which you can use if your computer has difficulty communicating with your CD-ROM drive. To use these drivers, select the CD-ROM drive option.

Important: Startup disks created with previous versions of Windows aren’t compatible with Windows 98.

To create a Startup Disk from within Windows 98

  1. Click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs.
    The Add/Remove Programs Properties dialog box appears.
  2. Click the Startup Disk tab, and then click Create Disk.
  3. Label a floppy disk “Windows 98 Startup Disk,” insert it into your floppy disk drive, and then click OK.

To start your computer using a Startup Disk

  1. Insert the Startup Disk in the floppy disk drive.
  2. Restart your computer.
    The Microsoft Windows 98 Startup menu appears.
  3. Type the number of the appropriate CD-ROM option, and then press ENTER.
  4. Follow the instructions on your screen.
After a series of scans, the MS-DOS prompt appears. From this prompt, you can gain access to the system files on the Startup Disk.

Note: If you normally use a CD-ROM drive and you start your computer with a Startup Disk, the drive letter designated to the CD-ROM may change for that session. For example, if your CD-ROM is normally drive D, it might be temporarily changed to drive E.
