Err Msg: Warning: Windows Multi-Boot May Not Function...

 Last reviewed: March 26, 1996

The information in this article applies to:
  • Microsoft Windows 95

SYMPTOMS

When you start Windows 95, you may receive the following error message: 

   Warning: Windows Multi-boot may not function correctly. Check for
   system files in your root directory with conflicting extensions.
After you receive this error message, Windows 95 starts normally.

CAUSE

This behavior can occur if one or more of the following files exists in the root folder of the boot disk:

  • Autoexec.dos
  • Autoexec.w40
  • Command.dos
  • Command.w40
  • Config.dos
  • Config.w40
  • Msdos.dos
  • Msdos.w40

RESOLUTION

Rename the files with .w40 extensions to names with an extension other than .w40. Rename the files with .dos extensions to names with an extension other than .dos.

MORE INFORMATION

When you boot Windows 95 to the previous operating system, it renames the existing Autoexec.bat, Config.sys, Command.com, and Msdos.sys files to files with an extension of .w40. It then renames the previous versions of these files from the .dos extension to the normal extension.

When you boot back into Windows 95, the Autoexec.bat, Config.sys, Command.com, and Msdos.sys files from the previous operating system are renamed back to an extension of .dos, and the .w40 files are renamed back to their normal extensions.

These files will not prevent Windows 95 from dual booting.
