89.SOLUTION : Windows 95 uses the MS-DOS compatibility mode when it is not using 16 or 32 bit disk access drivers. To fix the prbolems, you could try the following:

• Go to Start>Run. Type regedit and click Ok. In Registry Editor, click on Edit > Find Type noide and click on Find Next. Delete all the entries that you find. Reboot the machine.
  
• If this does not work, go to Start>Settings>Control Panel>System . In the Device Manager tab, check if the Primary and Secondary IDE, check if the Primary and Secondary IDE channels have any conflicts(exclamation marks next to them). Select Standard IDE/ESDI Hard Disk Controller and Click Remove.
  
• Reboot the system. Windows should detect the Primary IDE channel. Don't allow Windows to reboot, and let it allow to detect the Secondary IDE channel. Now continue to boot into Windows 95 and then reboot from the Shutdown menu.
  
• If this does not work, you should format the Hard Disk and repartiton using fdisk.
