Found this "laying around" in an old folder.
With some minor alterations made, it is still current.
(do not forget to make backups of precious files first).

****************************************************************************
Here are the steps you can take to duplicate dual boot installation:
****************************************************************************

1.  Copy (duplicate) the whole Windows directory and all it's sub directories
     to another directory, like \WIN31.  Copy the \DOS directory to another
     one as well, like \DOS6 .

2.  Edit all the INI files in the WIN31 directory and change all references
     from \WINDOWS to \WIN31.  The "find and replace" command in most
     word processors makes this easier, but be sure you save them as text files.

3.  Boot up your PC and install Win95 SETUP through windows program 
     manager "FILE-RUN".
     As you install WIN95 it will rename your CONFIG.SYS AND AUTOEXEC.BAT
     files to CONFIG.DOS and AUTOEXEC.DOS.  (When you dual boot it renames
     them back to CONFIG.SYS AND AUTOEXEC.BAT....and then
     backups the WIN95 versions as .W40).

4.  After Win95 finishes installing and you are on the desktop, use notepad with
     "select all files *.*"  to edit the CONFIG.DOS and AUTOEXEC.DOS files and
     change all \WINDOWS references in them to \WIN31, and
     all \DOS references to \DOS6 .

5.  In order for the dual boot menu to work, the following lines must appear in
     the [Options] section of your MSDOS.SYS file:   (If you use Doublespace or
     Drivespace disk compression you must change both MSDOS.SYS files - one on
     the boot drive and one in the compressed drive)

  [Options]
  BootGUI=1
  Network=0
  BootMulti=1
  BootMenu=1
  BootMenuDefault=7  (original DOS as default.  Use 1 for Win95 default)
  BootMenuDelay=5    (number of seconds to select something else)
  ;

(Note the semicolon). 
To add these lines, first, open "My Computer" and use the menu bar to 
VIEW - OPTIONS - VIEW - Show All Files, and also unclick "hide MS-DOS 
file extensions".  Then double-click on the MSDOS.SYS icon and look.   
If it doesn't have all the above lines, you'll need to edit this file
and put them in.   

Since the MSDOS.SYS file is "read-only-hidden" you'll need to first 
change the file attributes and then use the notebook editor to insert 
the new line(s).  Then you'll have to change the attributes back to 
their original states when done to protect the file.

To change the attributes, click on the MSDOS.SYS icon using your RIGHT
mouse button.  Select Properties and uncheck the attribute blocks.
Exit and make your text changes, then save the file.  Then put the 
attribute check marks back where they were.

 7.  Now, exit Win95 and re-boot.  You should now see the boot menu and
be able to select which mode you want to boot into.

Remember, any programs you install after this will only appear in the
system you were running at install time.   For example, if you install 
MS Word under Win95 you will have to install it again under old 
DOS/Windows if you want to run it both ways.  You can install the 
program to the same directory both times and you'll simply overwrite
the files and avoid having two sets of the new program on your hard drive.
