- 1. Introduction
-
- There are a number of documents available that describe in detail how
- to multiboot just about any number of OS's using NT's OS loader. When
- I finally bought Windows NT, I already had Windows 95 and Linux
- installed on my system and I was using LILO to multiboot between them.
- I decided to add Windows NT to LILO instead of using NT's OS loader.
-
- Originally I had Windows 95 on my first IDE disk drive and Linux on my
- second IDE disk drive. The Linux drive became my third IDE drive and
- I installed a new IDE disk for Windows NT as my second drive. Even
- though I haven't tried this in different configurations, I believe the
- order with which each OS is installed or which drive it is installed
- on is unimportant.
-
- Just remember to create those emergemcy bootup floppies when each OS
- prompts you to!
-
- Because I used Gilles Vollant's BootPart utility and BootPart only
- supports drives up to 4GB in size, this may not work if you have
- drives of larger capacity. If you need to work with drives greater
- than 4GB, contact Gilles directly (see BootPart documentation for
- Gilles' e-mail address).
-
-
-
- 2. Installing the Operating Systems
-
- When you install the OSes, make sure that all are installed on
- bootable partitions. I installed both Windows 95 and Windows NT on
- Fat 16 partitions, so this procedure works on Fat 16 drives. If you
- decide to use Fat32 for Windows 95 and NTFS for Windows NT, check to
- see if your version of Linux supports them and, if so, to what extent.
-
-
- 2.1. Installing Windows 95
-
- Install Windows 95 on your first drive. This will be your C: drive.
- Remember to create the Windows 95 boot floppies when prompted to do
- so.
-
- I have found that it is better if the Linux drive is removed from the
- system when installing Windows 95, so that it is never detected and it
- doesn't exist as far as Windows 95 is concerned.
-
- At this point, if you did everything correctly, you should be able to
- boot Windows 95.
-
-
-
- 2.1.1. Installing Windows NT 4.0
-
- Install Windows NT 4.0 on your second drive. When you create the
- partition on this drive, make the partition bootable. Not all
- versions of Linux support NTFS, so I created a FAT16 partition, just
- to be on the safe side and because I wanted to exchange data between
- the Windows drives.
-
- When Windows NT installs, it will detect the presence of Windows 95
- and will create an entry for it in the NT OS loader and you should see
- three entries in the OS loader menu as follows:
-
-
- Windows NT Workstation Version 4.00
- Windows NT Workstation Version 4.00 [VGA mode]
- Microsoft Windows
-
-
-
-
- At this point, if you did everything correctly, you should be able to
- multiboot to Windows NT and Windows 95.
-
-
-
- 2.1.1.1. Installing Linux
-
- Install Linux on your third drive. When I installed Linux, I only had
- Windows 95 installed so I only added the Windows 95 partition to Lilo.
- You can go ahead and install all OSes while installing LILO, or edit
- the Lilo configuration file later. However you decide to do it, I
- will show you how the /etc/lilo.conf file is supposed to look in the
- next section. Once Linux is installed, you should be able to boot to
- Linux.
-
-
-
- 3. The Linux part
-
- This will involve editing the /etc/lilo.conf file and reinstalling
- LILO. The following should already be present in /etc/lilo.conf:
-
-
- boot=/dev/hda
-
-
-
-
- The Linux stanza should also be already present:
-
-
- # Linux stanza
- image=/vmlinuz
- root=/dev/hdc1
- label=Linux
- # End Linux stanza
-
-
-
-
- Now add the Windows 95 stanza:
-
-
- # Windows 95 stanza
- other=/dev/hda1
- table=/dev/hda
- label=Windows95
- # End Windows 95 stanza
-
-
-
-
- Now add the Windows NT stanza:
-
-
- # Windows 95 stanza
- other=/dev/hdb1
- table=/dev/hda
- loader=/boot/any_d.b
- label=WindowsNT
- # End Windows 95 stanza
-
-
-
-
- Now run LILO again. At this point, if all is well, you should have
- Windows 95, Windows NT, and Linux as selections from LILO. You should
- be able to boot to Linux and Windows 95 (which should give you the
- Windows NT OS loader). To make the Windows NT entry operational, you
- still need to do some work on the Windows NT side.
-
-
-
- 4. The Windows NT part
-
- Before you can continue, you need two do two things.
-
- The first is to download and unzip Gilles Vollant's BootPart utility
- which can be found at <http://www.winimage.com/bootpart.htm> with
- some information on how to use it.
-
- The second thing to do is copy (do not delete them yet!) the following
- files to the root of the Windows NT drive:
-
-
- Boot.ini
- Bootsect.dos
- Ntdetect.com
- Ntldr
-
-
-
-
- These files are the Windows NT loader. They are located in the root
- of the Windows 95 drive and were placed there by Windows NT when you
- installed it.
-
- Once this is done, boot to the Windows 95 DOS prompt (press Shift+F5
- when Windows 95 loads) and issue the following command:
-
-
- BOOTPART WINNT BOOT:D:
-
-
-
-
- Now you must edit Boot.ini in your Windows NT root directory. You
- must edit three lines, one in the [boot loader] section and two in the
- [operating systems] section.
-
- This is the original Boot.ini:
-
-
- [boot loader]
- timeout=30
- default=multi(0)disk(0)rdisk(1)partition(1)\WINNT
- [operating systems]
- multi(0)disk(0)rdisk(1)partition(1)\WINNT="Windows NT Workstation Version 4.00"
- multi(0)disk(0)rdisk(1)partition(1)\WINNT="Windows NT Workstation Version 4.00 [VGA mode]" /basevideo /sos
- C:\ = "Microsoft Windows"
-
-
-
-
- This is the new Boot.ini:
-
-
- [boot loader]
- timeout=30
- default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
- [operating systems]
- multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation Version 4.00"
- multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows NT Workstation Version 4.00 [VGA mode]" /basevideo /sos
-
-
-
-
- Notice that all instances of rdisk(1) have been changed to rdisk(0)
- and the line referencing Windows 95 has been removed.
-
- After saving Boot.ini, if you did everything correctly, you should now
- be able to boot to Windows NT from LILO.
-
-
-
- 5. The Windows 95 part
-
- Create a bootable DOS floppy from the Windows 95 DOS prompt (press
- Shift+F5 when Windows 95 loads). It is important that this floppy be
- created at the DOS prompt, not from a DOS window inside Windows95! Do
- not boot to Windows95 until this step is complete! Copy the file
- C:\WINDOWS95\COMMAND\SYS.COM to the floppy (substitute your Windows95
- path if different). Now boot from the floppy and enter the command:
-
-
- SYS C:
-
-
-
-
- This should have removed the Windows NT OS loader and you should be
- able to boot directly into Windows 95 from LILO.
-
- You can now remove the NT loader files:
-
-
- Boot.ini
- Bootsect.dos
- Ntdetect.com
- Ntldr
-
-
-

- 6. References
-
- Thanks to the following people (in no particular order):
-
- James C. Bevier & D. Michael McFarland. In a message exchange on the
- reddhat-list they provided some information on how to boot NT from
- Linux.
-
- Gilles Vollant. BootPart is a very useful utility and Gilles makes it
- available for free with some nice documentation. Thanks Gilles.
-
- Mike Harlan. By reading his 'Linux-DOS-Win95-OS2' mini-HOWTO, it
- helped me make some assumptions about LILO's behavior.
