Linux first, NT after
1. Install a minimal Linux (hold off on installing the rest until
you win the Linux/NT battle). Do all your disk partitioning in
Linux, including your NT partition (make it FAT). I was not
successful at making more than one NT partition. I also made it the
first partition, but I don't know if that is essential or not.
2. Edit /etc/lilo.conf and use boot=/dev/sda (I was not successful
at installing LILO on the Linux partition--/dev/sda3 in my case) and
run "lilo". You'll have to use the editor ae. You'll live.
3. Save the MBR with this: dd if=/dev/sda of=/dev/fd0 bs=512 count=1
Use a floppy. Trust me. Also do this each time you change the disk
partition table.
4. Install NT, part 1. When it goes to reboot halfway through the
process you'll boot into Linux.
5. Add NT stanza to /etc/lilo.conf, e.g.:
other=/dev/sda1
label=NT
table=/dev/sda
and run lilo. If lilo complains about this (I forget the message),
add the "linear" flag to /etc/lilo.conf near the "compact" keyword.
Furthermore, if your partition table is screwed up by NT you'll
either need to use "ignore-table" or follow the directions in Step 7.
See also "fix-table". The LILO HOWTO is your friend.
6. Reboot, select NT from LILO, and finish NT install. You'll need
the "Boot Disk XU, HP Vectra AIC 7880 Driver A.01.02" floppy to
install the ethernet drivers and the "XU/VT Drivers and
Documentation" CD (directory video/disk4 if I recall correctly) to
install the video drivers for the Matrox MGA Millennium.
7. Back to Linux, run fdisk and ensure you don't get "partition
doesn't end on cylinder boundary" on your Linux partitions. You'll
still have this error on the NT partition though, but this seems to
be OK.
/dev/sda1 1 1 322 329301 6 DOS 16-bit >=32M
Partition 1 does not end on cylinder boundary:
phys=(321, 39, 9) should be (321, 63, 32)
Cfdisk reports strangeness, but it seems OK:
Unusable 0.04*
/dev/sda1 Primary DOS 16-bit >=32Mb 321.59*
Unusable 0.39*
If you do get the cylinder boundary warning on your Linux
partitions, it is sufficient to use cfdisk to do something innocuous
like changing the boot sector.
If, however, NT has really screwed you over and cfdisk can't even
run, complaining that it cannot open /dev/sda, then you'll need to
take more extreme action. You'll need that MBR you saved
previously. Clear and restore the MBR (but not the signature) with:
dd if=/dev/zero of=/dev/sda bs=512 count=1
dd if=/dev/fd0 of=/dev/sda bs=510 count=1
8. Install the rest of Linux. Easy, huh?
If you prefer to have NT write the MBR instead of LILO, you may have
to resort to the following to clear the MBR first:
- dd if=/dev/zero of=/dev/sda bs=446 count=1 (in Linux) or perform
a low-level format with the SCSI utilities. I've heard that a
low-level format of an IDE disk is fatal, so don't do it.
- fdisk /mbr (you've obviously already created a DOS boot disk that
contains fdisk).
- delete NT partition and create it again in NT install.
- continue with NT install.
Epilogue: After first posting this message, I heard from several
folks that they had no problems with NT's Disk Administrator, and
were able to install either NT or Linux first without any problems.
Hopefully, you'll be in this camp, but if not, perhaps this campfire
story will be of some use.
Since the first edition of this mini-HOWTO, others have written
similar documents as well. Please be sure to consult them. If your
experience differs from any presented, then you should submit your
own mini-HOWTO or submit a revised version of this document to the
HOWTO maintainer (reference this sentence) and send a carbon copy to
me as I don't have the time to maintain this document. Someone
should eventually combine all of these documents into a single
coherent HOWTO.
Finally, I'm afraid this document details all I know about this
subject. I should point you to an appropriate Linux newsgroup for
further information. I use NT about one day a year. Under duress.
NT first, Linux after
If you have one IDE hard disk
- First of all, I would suggest you to install a fresh copy of
Windows NT 4.0 on your hard disk. I suppose that you already
made a backup of your important data, so the NT installation
shouldn't be a problem. During the NT installation, setup is
not going to ask you where to place NT's boot loader, so it
would be placed into the MBR (Master Boot Record) of your hard
disk. But, there is a possibility for a previous content of
the MBR to remain within the MBR (especially any previous
Lilo), so I would suggest you (before installation of NT) to
boot the computer with a DOS floppy diskette having DOS version
of FDISK. At the prompt a:\ just enter the command: fdisk /mbr
and restart the computer again (without that floppy).
- After you have successfully installed your NT, you will see that
it uses the whole hard disk or a specific partition of the hard
disk (depending on what you decided during the setup process).
So, it is advisible to 'shrink' the partition where NT resides
in order to make some free space on the disk. Onto that free space
you will install your Linux. After you have your NT configured
and running, you have to boot your computer using a floppy
diskette with Partition Magic utility by Power Quest. It is a
graphical tool able to see all partitions on all hard disks you
have. The best thing is that you can make some changes with your
partitions but not to destroy your existing data. One of the
available changes is to make your existing partition(s) smaller,
so to get some free space on the disk(s) for other purposes.
Although you are advised to make a backup before you make any
changes to the partitions, I usually practise to 'shrink' NT's
partition before I installed anything but NT itself (so, if
needed, a repetitive re-installation wouldn't be a problem).
Well, Partition Magic (or any other similar utility you are
familiar with) will shrink your NT's partition (either NTFS or
FAT) to a smaller measure and place it to either the beginning
or to the end of the previous measure. It means that you may
choose to have your 'shrinked' NT partition at the beginning
or at the end of your disk (I usually choose NT to be at the
beginning, so the ending part of the disk will become a 'free
space'). After the 'shrinkin' is finished, you may re-boot your
NT in order to check the new situation: you may use Windows
Explorer or Disk Administrator for that.
- So far so good. Next step is to install your Linux. Case you
are familiar with RedHat distribution (I hope with other distros
is the same or similar), you start by putting your installation
CD in the drive and re-boot the computer). Well, when you are about
to choose what type of installation it will be (Gnome or KDE
Workstation, Custom, etc.) you may choose whatever you planned
before, but I would suggest to install a Workstation at first.
This is good because Linux setup will find automatically the
free space on the (first) hard disk, make all partitions needed
for Linux, format them properly, make majority of options by
default so you won't have much pain during the setup (later, if
you want, you may either add missing components or re-install
Linux as Custom over the existing linux partitions). Lilo should
go to the MBR.
- After it looks that Linux installation is finished, you are going
to re-start the computer and there you will only see Lilo
with one Linux entry to boot (or maybe more than one Linux
entry, in case your hardware is multi-processor one). But, don't
panic! Your Windows NT is still there where you had installed it
before Linux. You should become some familiar with Linux as soon
as possible, in order to be able to find and edit your new
/etc/lilo.conf file. When you open this file for the first time,
you'll see that there is only one (or more) Linux entry. Well,
you should know the exact position (read: a partition) where
Windows NT has been installed, so you could add an appropriate
entry into /etc/lilo.conf file. After you do that, restart Lilo
and, after the next re-boot, you will have both 'linux' and 'nt'
entries under Lilo menu. My added NT entry is:
other=/dev/hda1
label=nt
If you have more than one (SCSI) hard disk
Notice: Folks, you see, at my place, one of computers has several
SCSI disks. That's why I put the word 'SCSI' in parentheses. There I
have several SCSI controllers, SCSI CD ROM drive and SCSI Tape drive.
So, it doesn't mean that *you* will be using SCSI parts at all.
You'd rather handle more than one IDE disks, but I hope that install
process shouldn't change too much, if any.
- First of all, I would suggest you to install a fresh copy of
Windows NT 4.0 on your other
disks, during the
Windows NT Setup After you have successfully installed your NT, you will see that
it uses the whole hard disk or a specific partition of the hard
disk (depending on what you decided during the setup process).
So, it is advisible to 'shrink' the partition where NT resides
in order to make some free space on the disk. Onto that free space
you will install your Linux. Well, you may also think of using
some other disk(s) you have for Linux (so did I). That case, you
would start your linux installation and try to use, for example,
/dev/sdb (or sdc, or sdd, or else in case of SCSI system) or
/dev/hdb (or hdc, or hdd, or else in case of IDE system). Looks
like Linux installation accepts whatever you choose, but somehow
after all was finished when I did that, LILO was no able to
do anything. Actually, it always stopped after 'LI' so it was
possible to start Linux at all. Finally, after pulling my hair
out, I decided to make it all on the So far so good. Next step is to install your Linux. Case you
are familiar with RedHat distribution (I hope with other distros
is the same or similar), you start by putting your installation
CD in the drive and re-boot the computer). Well, when you are about
to choose what type of installation it will be (Gnome or KDE

This is the second release featuring more samples and an improved structure.
Beside that, this version of Linux+WinNT mini-HOWTO is going to offer you
another procedure to install both Linux and NT on your computer. And doing
that on both IDE and SCSI disks.
This mini-HOWTO would be improved from time to time. If you think
that the HOWTO on your Linux installation CD is some out-of-date, you
may check for newest release on the Internet. It could be found within
the main
homepage.

If you are about to ask any questions about the kernel you should
read this first, it will save you and many others a lot of time

In the end you might find yourself unable to solve your problems and need
help from someone else. The most efficient way is either to ask someone
local or in your nearest Linux user group, search the web for the nearest
one.
Another possibility is to ask on Usenet News in one of the many, many
newsgroups available. The problem is that these have such a high
volume and noise (called low signal-to-noise ratio) that your question
can easily fall through unanswered.
No matter where you ask it is important to ask well or you will not be
taken seriously. Saying just

- DMA
- IRQ
- Chip set (LX, BX etc)
- Bus (ISA, VESA, PCI etc)
- Expansion cards used (Disk controllers, video, IO etc)
- BIOS (On motherboard and possibly SCSI host adapters)
- LILO, if used
- Linux kernel version as well as possible modifications and patches
