A text file describing a step-by-step procedure I developed to install a
dual-boot menu function for my DOS 6/Win 3.11 and Win95 systems. This
way, I can choose which system I want to use at boot-up. DoubleSpace and
DriveSpace drives can also be handled with this configuration. Use this
method to continue running your critical programs under your old DOS/Win
system while you're testing Win95.
*********************************************************************
I wanted to install a dual boot with Win95 & WFWG 3.11 so I could try
out Win95 without sacrificing my old system setup. Here are the steps
you can take to duplicate my 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)
;
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.
