Allow Booting to the Previous Operating System

If you installed an upgrade version of Windows 9x, you can normally press F4 to boot your previous version of Windows. This option can be disabled.

1. Change the attributes for MSDOS.SYS so it is not 'Read Only', MSDOS.SYS is found in the root directory of your C:\ drive. Open the file using Notepad or another text editor (not Microsoft Word or any word processor).


2. Change the value of 'BootMulti=' to 'BootMulti=1' for F4 enabled or 'BootMulti=0' for disabled.


3. Changes will take place on the next reboot.
