Dual boot win 95/98 & Min NT

I am planning on doing the same Dual boot setup as jjenkins. I currently run Windows 95B (FAT32) on a P-200 Pro with 64MB RAM and only one 3.5G Hard Drive. The drive is currently partitioned into two (C: & D:) 2G & 1.5G partitions. I am planning to do a format of the drive.

Should I partition the Drive?
If I choose to again partition drive (FAT16 this time) is this done from Win 95/98?

Should I look into purchasing another larger harddrive?

And if I plan to upgrade the Win 95 OS to Win 98 soon, should I upgrade before setting up the Dual Boot? Or can I Upgrade Win 95 within Dual boot system at a later date?

1 Solution
I did something similar to you recently. I had 95 and NT running side by side on a single drive except mine was on a 3.2GB drive.

Since you're alright with formatting the drives, go ahead and do that. Install win95 on the 2.0GB partition with FAT16 (yes, this is done within win95). Fat32 is an option that you can select or unselect.

Put NT on the other partition (this will give you more flexibility if and when you have to reinstall either OS for whatever reason). Make sure its FAT formatted as well if you intend to be able to use files on either partition.

If you can afford to, buy another drive and add it to the mix. Then  leave win95/98 on the 2.oGB partition, keep NT on the 1.5GB partition (convert to NTFS for better performance[optional]) and use the new drive (FAT16, formatted using disk administrator in NT) as a shared space for files and folders.

-you're going to have to install applications twice, once for NT and once for win95/98 because they use different registries. That means you're going to need a lot of disk space.
-Remember you have to use FAT16 if you want to use files between NT and 95/98.
-NTFS gives you better performance for partitions over 500MB in size.
-you should be able to upgrade from 95 -> 98 without a problem because the boot loader will still point to the same place.

Good luck

For installing applications twice, once for NT and once for win95/98, is it not true that the programs can be installed to the same folder (location) thereby not doubling reguired space?
Can programs all be loaded to the 2.0G (Primary partition)?
Does loading each OS to different partition allow for ease in later removing Win 95/98 and going soly with Win NT SR2? Also should sole OS be on primary partition?
You are correct regarding the installing applications to the same folder. Just verify that the programs you are installing are compatible with both NT and 95. Then again some applications, act up when you do this. For whatever reason, Photoshop does not like this on my home workstation, but doesn't mind it at work. Go figure. To this I say "your mileage may vary."

You can load the programs to the primary partition, but in the event that you wipe that partition out because you need to repair the OS, or something else bad happens, then you're going to have problems with the other OS that might have registry keys that reference that location on the primary partition.

Henceforth I go back to my original recommendation about putting shared files all on one partition. This will save you headaches in the future. Also, if you have the space and want to ensure that your critical applications work with their intended OS, then install 2 copies versus the single one. Its just precaution.

I would install 95 first, then NT second to different partitions. This makes using the boot loader a lot easier. In the event that you want to get rid of 95/98 in the future, I would refer to MS article Q92393 in the online support section on the microsoft website. It fully explains how to remove an OS from the primary and reclaim that space for something while fixing the boot loader to boot to NT correctly.

Regarding putting the OS's on seperate partitions, I would highly recommend it. Especially if you have any inkling that you might remove one OS or the other. And lets be honest, even as an MCSE, I have had to format an MS installation just because it was getting too slow, corrupted or otherwise and I couldn't/didn't want to go through the hassle of fixing it.

-remember to make ERD's (Emergency repair disks) often for both NT and 95/98, because they may be the only way to revive a corrupted OS, without having to reinstall all your application over again on your machine-->if you install all your apps to a shared location.

I just saw some of your posts in jjenkins question. leew, is a good guy. I think he gets a kick out of just answering people's questions. He's right, some people are so hell bent on points its sick. Some people have no etiquette.

If you decide to reject my answer to give leew the points, I won't be upset. Just don't give them to Mujeeb, he's rude->IMHO.

From what I've seen Blackman and Wayneb are also good guys and have really solid NT skills as well.

Thanks dsrikump, you have been more than helpful. Thanks for the references. One further comment:
You stated, "putting shared files all on one partition". Does this mean that if I don't breakdown and get a larger "up-to-date" HDD, that I should actually Partition my 3.5G (actually 3.8G) into three sepatate partitions. One Primary (For Win 95/98 and Two Secondary (For Win NT & Software/Data). Probbably best to just purchase another HDD.
I increased the points for additional input.
Should I update Win NT 4.0 SR2 to SR4? ( I am running Win NT 4.0 on a laptop which I use to travel.)
Can install Win 95/98 to the Laptop as the second OS to the Existing NT OS which it now has?

I typed in 70 Points and it seemed to show only 7 Points?

I would go with 3 partitions personally, but two will do. If you can afford the extra harddrive, then hold out and put all your shared files and applications there. Of course this is a laptop so I guess hardware additions can be harder to come by.

I would also defininetly upgrade to service pack3 or service release3 as you call it. It fixes many problems, and increases stability and compatibility with many programs. I haven't applied service pack 4 yet to any of my machines as I wait in anticipation of bug announcements and incompatiblity problems. Although so far, these are few are far in between as far as I'm concerned.

Regarding the points, don't sweat it. I'm not one of the point mongers.

The original question "The Dual boot" Machine is a P-200 Pro Desktop. The laptop is a NT System which i had not planned to make a Dual boot System. I was only thinking now of making it a dual boot Win 98 & Win NT System to make "life" easier on the Road with the laptop. The Laptop is a P-233 w/ 64MB Ram & 2.0G HDD (non-partitioned).
If I choose to also make the laptop a "Dual boot" System, should I uninstall Windows NT & reinstall it after first installing Windows 95/98?
I would go that route, unless you have partition magic and then you can can forgo, the uninstalling and installing routine. Then refer to Microsoft online support article # Q92393. Which talks about how to operate the boot loader correctly in the case that you leave NT on--and install 98 second. The article talks about DOS 6.22 but this information still applies. I will copy the whole article in the next comment.
Installing MS-DOS 6.x Upgrade with Dual-Boot Schemes
Installing MS-DOS 6.x Upgrade with Dual-Boot Schemes
                  Last reviewed: November 23, 1994
                  Article ID: Q92393
The information in this article applies to:

Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22


This article describes how to install MS-DOS 6.x Upgrade Upgrade on systems running Windows NT, OS/2, or UNIX/XENIX.


To install MS-DOS on a machine that is already running Windows NT, the C partition must be formatted as an MS-DOS FAT drive and set as the primary, active partition.

If the file system on drive C is not an MS-DOS FAT partition, refer to section 1.9 of the README.TXT file on the MS-DOS Setup Disk 1.

If Windows NT is installed on a FAT partition, the procedure you use for installing MS-DOS depends on whether or not you already have a version of MS-DOS installed.

If You Are Running Windows NT but Do Not Have MS-DOS Installed

Run Setup by placing the MS-DOS Setup Disk 1 in drive A and restarting your computer. You may receive a message stating that MS-DOS files were found on the system, even though there is no version of MS-DOS on the machine. If you receive this message, continue Setup.

NOTE: If your MS-DOS disks are not compatible with your drive A, follow the instructions in the "Manually Installing MS-DOS" section below.

Follow the prompts on the screen.

Setup may overwrite the Windows NT boot sector. As a result, Windows NT may not load after Setup reboots your computer. To restore the Windows NT boot sector, follow the instructions in the "Restoring the Windows NT Flex Boot Loader" section below.

You Are Running Windows NT and MS-DOS Is Installed (Boot Loader)

When you start the computer, choose MS-DOS as the operating system.

Run MS-DOS Setup by inserting Setup Disk 1 in drive A or B, typing
"a:setup" or "b:setup" (without quotation marks) at the MS-DOS command prompt, and then pressing ENTER. Follow the instructions on the screen.

Setup may overwrite the Windows NT boot sector. As a result, Windows NT may not load after Setup reboots your computer. To restore the Windows NT boot sector, follow the instructions in the "Restoring the Windows NT Flex Boot Loader" section below.

Manually Installing MS-DOS on a Windows NT Machine

Use this procedure if the MS-DOS Upgrade disks are not compatible with your A drive.

Create a bootable floppy disk for drive A by going to another computer that is running MS-DOS, inserting the MS-DOS Setup Disk 1, typing "a:setup /f" or "b:setup /f" (without the quotation marks), and pressing ENTER. Follow the instructions on the screen to create the Startup disk.

Place the newly created Startup disk in drive A of the Windows NT
computer on which you want to install MS-DOS.

Restart your computer by pressing CTRL+ALT+DEL.

Transfer the system files from drive A to C. To do this, type "sys a: c:" (without the quotation marks) at the MS-DOS command prompt and press ENTER.

Put the MS-DOS Setup Disk 1 in the floppy disk drive and run Setup with the /U and /Q parameters to manually copy all MS-DOS files to the hard disk drive. For example, put Setup Disk 1 in drive B, type "b:setup /u /q" (without the quotation marks) at the MS-DOS command prompt, and then press ENTER.

Setup may overwrite the Windows NT boot sector. As a result, Windows NT may not load after Setup reboots your computer. To restore the Windows NT boot sector, follow the instructions in the "Restoring the Windows NT Flex Boot Loader" section.

Restoring the Windows NT Flex Boot Loader

To re-enable the Windows NT boot sector, start your system using
Windows NT Disk 1
- Setup Disk for Floppy Disk Installation (or Disk 1
- Setup Disk for CD-ROM Installation if Windows NT was set up using a CD-ROM).

At the first blue screen, press R for Repair.

When prompted to do so, insert the Emergency Repair Disk that was
created for this computer when you first installed Windows NT. Follow the instructions on the screen.

Several options appear on the screen, and all of them are selected by default. Clear all these options except "Verify Boot Files on Your C: Drive."

To clear an option, use the ARROW keys to select the option, and then press SPACEBAR to clear it.

Select Continue, and press the ENTER key. The Emergency Repair Disk runs CHKDSK, verifies the startup files are valid, and then rebuilds them if necessary.

When the procedure has completed, you are prompted to restart your
computer. When the system restarts, the Windows NT Boot Loader screen appears, allowing you to choose MS-DOS or Windows NT.


If OS/2 is installed on your system without a dual-boot scheme in place (such as Dual Boot or Boot Manager), refer to the MS-DOS 6 "User's Guide," Chapter 1, page 5.

The setup programs for MS-DOS 6 Upgrade and MS-DOS 6.2 preserve OS/2 command-line-driven dual-boot programs but disable OS/2 boot-sector-driven (that is, menu-displayed) dual-boot schemes. The newer boot-sector-driven programs, such as Boot Manager, can easily be restored after Setup
completes the installation of MS-DOS.

Boot-Sector-Driven Schemes (OS/2 Versions 1.1 and 1.2)

Microsoft OS/2 version 1.1 and Compaq OS/2 version 1.2 use the boot-sector-driven dual-boot feature. With these schemes, the boot sector loads a menu from which you choose the operating system you want to start. MS-DOS Setup overwrites this information, thus disabling OS/2; you must reinstall OS/2 to enable this feature.

Command-Line-Driven Dual-Boot Schemes (OS/2 Versions 1.3, 2.0, and 2.1)

The command-line-driven dual-boot feature (referred to as Dual Boot) uses a scheme in which the boot sector of the bootable partition (usually C) is rewritten to point to either DOS or OS/2 boot files in the same partition. The BOOT command (BOOT /DOS or BOOT /OS2) is used to set the desired boot record. After running the BOOT command, the machine must be rebooted to load the operating system.

Before running the MS-DOS Setup program, the system must be booted to the MS-DOS operating system. To do this, run the BOOT /DOS command and reboot the computer. MS-DOS Setup does not affect the Dual Boot configuration.

Boot Manager (OS/2 Versions 2.0 and 2.1)

Boot Manager uses a 1-megabyte non-DOS partition on the boot disk. A menu is displayed at startup, allowing you to select which operating system to load. The menu can be set to a zero time-out; in which case, the default operating system is automatically loaded and no menu is displayed. Once a selection is made from the menu, Boot Manager turns over control to the logical boot sector on the partition that was selected and boots that operating system.

To run the setup program for either MS-DOS 6 Upgrade or MS-DOS 6.2 Upgrade, boot to the MS-DOS operating system, and then run MS-DOS 6.0 or 6.2 Setup. After Setup has installed MS-DOS, Boot Manager is disabled because the MS-DOS FAT partition is the active partition. To re-enable Boot Manager, run the Fdisk program to set the 1-megabyte non-DOS partition to Active.

NOTE: The Boot Manager utility that ships with OS/2 versions 2.0 and 2.1 can also be used on systems running OS/2 version 1.3.


If your system is set up for dual-boot functionality and you have not installed the MS-DOS 6 Upgrade or the MS-DOS 6.2 Upgrade, you should manually install MS-DOS. If your system was set up for dual-boot functionality with UNIX or XENIX and you installed MS-DOS using the /U switch, use the following procedure to restore the dual-boot functionality:


Choose 2 and press ENTER to set the active partition.

Choose the UNIX partition.

Exit Fdisk.

Restart your computer.

Consult your UNIX or XENIX documentation to restore the dual-boot

For more information on installing the MS-DOS 6 Upgrade on a system with UNIX or XENIX partitions, refer to the following section in Chapter 8 of the Microsoft MS-DOS 6 "User's Guide":
