A REAL Boot Disk For Windows 95

[Q] "Dear Digital Goddess, When I originally installed Windows 95 on my
machine I was asked to create a boot disk, but I ignored this step. Can I
still create this disk?" Bob in Seattle, WA


[A] You may not believe this, Bob, but I run into this question more often
than even I care to admit. It seems that in our haste to try out something
new, we quite often overlook the mundane yet necessary computer filing
tasks like making backups or creating boot disks that don't effect you
until you really need them and they aren't there.

First, let's answer your question, and then go about showing you how to
create this potential rescue disk. Get ready to breathe a big sigh of
relief, Bob - as long as your machine still has access to Windows, you can
create this disk. And being the benevolent and kind "Digital Goddess" that
I am, I'm going to show you how to create a REAL Windows 95 Boot Floppy,
not just the simple rescue disk that Microsoft has you create upon initial
installation of Windows 95. This floppy disk will allow you to boot your
computer without having to access the hard drive, and contains all the
necessary operating system files your computer needs to get started. Boot
disks can be a lifesaver when hard drives crash or become infected with
viruses, and really, no computer user should be without one.

So let's get started. The step-by-step instructions are going to be
somewhat detailed, so I recommend printing this tip out in full so you can
refer to the sheet while creating this disk. Let's begin by explaining what
I meant above by a REAL Windows 95 Boot Floppy...

The disk that Microsoft originally asked you to create when you installed
Windows 95 for the first time includes all the critical files necessary to
start your computer and access your hard disk. This disk also includes
important disk utilities such as Scandisk.exe, Fdisk.exe and Format.exe,
but that same disk will not be able to recognize your CD-ROM drive -
meaning you won’t be able re-install Windows 95 from a CD. And if your
original copy of Windows 95 came on a CD-ROM (which most since 1996 have),
you'll be up the proverbial creek without a paddle, whether you have this
boot disk or not.

What I am going to show you goes a step beyond the simple MS Rescue Disk
version and includes the drivers and utilities needed for CD-ROM
recognition from the boot disk, allowing you re-install Windows 95 from its
original CD with no hassles. For Windows 98 users this isn't a problem -
Microsoft included a copy of the most generic CD-ROM driver, IDE/ATAPI,
right in the Windows 98 Rescue Disk, so there are no drive recognition
problems for these users.

Okay, let's make a REAL Windows 95 Boot Disk - 

1. First, open Add/Remove Programs in Control Panel and click on the
Startup Disk tab. Then click on Create Disk. You’ll be asked to insert the
original Windows 95 CD into your CD-ROM drive and to put a floppy disk into
the A:\ drive. After the disk copies, you’ll have a floppy that includes
all the critical files necessary to start your computer and access your
hard disk, but you won't have those all-important CD-ROM files.

2. Now locate the real-mode driver for your CD-ROM. Please be aware that is
different from the 32-bit Windows 95 driver that your CD-ROM normally uses
in day-to-day operations. These 32-bit drivers have the file extension .vxd
and are called virtual device drivers. Real-mode CD-ROM drivers end with a
.sys at the end of their file name and can usually be found on a separate
floppy that came with the computer. If you can't locate this file or lost
the original floppy, don't despair, you can download it from the web at any
of several sites. Two that I highly recommend are The Driver Zone
(http://www.driverzone.com) and WinDrivers.Com http://windrivers.com. 

3. After locating or downloading your CD-ROM Driver's .sys file, copy it to
the Boot Disk and then locate the system level CD-ROM driver in Windows
called MSCDEX.EXE. It's usually located in your Windows/Commmand folder on
your C:\ drive. If you don't find it there check your original Windows 95
CD-ROM. Copy this file over to the boot disk as well. 

4. Now you need to add a line to the config.sys file on the floppy. To do
this, open an MS-DOS window and switch to the A:\ drive by typing in A: at
the prompt and hitting Enter. Once you get the A:\> prompt, type in "edit"
(no quotes, please) and hit Enter. This opens up the DOS EDIT tool on the
floppy. Find the config.sys file, which should have only one line that
refers to HIMEM.SYS. (NOTE: If this file has more than this one line, check
to make sure that you haven't opened the C:\ drive's config.sys - if you
edit this file you'll be in BIG TROUBLE later!!). If you're in
A:\config.sys, toggle your cursor past the HIMEM command and type:

Device=A:\(name of your CD-ROM .sys file) /D:MSCD001 

NOTE: After several readers wrote in to notify us, we now know that the "D"
DOES NOT represent the letter of your CD-ROM drive (in some cases E:, F: or
G:). It actually should be typed as is it is above, whether your CD-ROM
drive letter is "D" or not! The machine will recognize the appropriate
letter for the CD-ROM drive on boot. (Thanks, loyal Komandos!!) 

Save the new config.sys file and close it.

5. Next, create a simple autoexec.bat file for the boot disk by opening a
new file from the File Menu command in the DOS editor. At the cursor type
the following:

MSCDEX.EXE /D:MSCD001

Then go to File Menu, Save As, and name this file autoexec.bat (again, make
sure it is on the A:\drive). Exit the DOS Editor and close the MS-DOS
prompt window.

Okay, that's it. Let's test this puppy, just for safety's sake. Insert the
boot floppy and restart your machine. You'll see some messages about MSCDEX
and a few other things right after your normal BIOS messages, and then you
should be at the A:\> prompt. To check for your CD drive, type in D:\ (or
the letter that your CD-ROM drive is attached to) and hit Enter (make sure
you have a CD in the drive drawer - it doesn't matter which one). To check
the CD-ROM drive's reading capabilities, type in "dir" (no quotes) after
the D:\> prompt and you should get a list of all the files and directories
on the CD you placed in the drawer.

Got it all? COOL!! Now you have a real, "true blue" Boot Disk that will
recognize your CD-ROM drive and will allow you to re-install Windows 95 no
matter what troubles come your way!
